First of all, let us thank the Almighty God for blessing us in the finalization of the Komodo National Park 25-Year Management Plan after a long preparation process that began in 1995. This Management Plan specifically tries to provide alternatives for various marine problems throughout the Komodo National Park and its surroundings. These areas are not only potential resources for the surrounding community; they also potentially handle strains for the conservation of nature. It is difficult therefore to disregard the marine component, although the land component containing the habitat of Varanus komodoensis is still the main symbol of this National Park and the management priority.
In order to anticipate challenges and uncertainties in several aspects (e.g., political, economical, social, culture and the environment), this management plan, with its priority on the conservation of biodiversity, focuses on management and the use of indicators in choosing alternative solutions.
In addition, this plan has been set up to accommodate site specifics, geographical conditions and the surrounding community demographics. In order to make this document an adaptive management guide, it will continuously be updated with recent information and analysis regarding management aspects, reviewing aspects of both biodiversity and the surrounding community. It is our hope that this Management Plan will provide an initiative that complements the current Basis of Preparation of National Park Management Plan.
Lastly we would like to extend our gratitude for the cooperation and support from various parties in finalizing this Management Plan. Hopefully this cooperation will continue in the implementation of this Plan.

1. INTRODUCTION TO THE MANAGEMENT PLAN
1.1 BACKGROUND
Komodo National Park (Fig. 1) was established in 1980 and declared a World Heritage Site and a Man and Biosphere Reserve by UNESCO in 1986. KNP was initially established to conserve the unique Komodo dragon (Varanus komodoensis), and its habitat. Other terrestrial species of note (Fig. 2) include the orange-footed scrubfowl (Megapodius reinwardt), an endemic rat (Rattus rintjanus), and Timor deer (Cervus timorensis). Approximately 70% of the terrestrial area is open grass-woodland savanna (Fig. 3). Tropical deciduous (monsoon) forest and quasi cloud-forest above 500 m on ridges and pinnacles are the other terrestrial habitat types.
Komodo National Park (KNP) includes one of the world’s richest marine environments (Fig. 4). The Park encompasses 1,214 square kilometers of highly diverse marine habitats, including coral reefs, mangroves, seagrass beds, seamounts, and semi-enclosed bays. These habitats harbor more than 1,000 species of fish, some 260 species of reef-building coral, and 70 species of sponges. Dugong (Dugong dugon), dolphins (10 species), whales (6 species), and hawksbill (Eretmochelys imbricata) and green (Chelonia mydas) turtles are all occurring within the Park. KNP lies in the Wallacea Region of Indonesia, identified by WWF and Conservation International as a global conservation priority area. KNP is located between the islands of Sumbawa and Flores, at the border of the NTT and NTB provinces (Fig. 5). KNP includes three major islands, Komodo, Rinca and Padar, and numerous smaller islands together totaling 603 km2 of land.
The total size of KNP is presently 1,817 km2. Proposed extensions of 25 km2 land (Banta island) and 479 km2 marine waters will bring the total surface area up to 2,321 km2. There were approximately 3,267 inhabitants living within the Park in 1999, spread out over four settlements (Komodo, Papagaran, Rinca and Kerora). An estimated 16,816 people were living in fishing villages directly surrounding the Park in 1998. Park inhabitants mainly derive their income from a pelagic lift net ('bagan') fishery that targets squid and small schooling pelagic fish.
Destructive fishing practices such as dynamite-, cyanide-, and compressor fishing severely threaten the Park's demersal (bottom dwelling) and sedentary marine resources by destroying both the habitat (coral reefs) and the resource itself (fish and invertebrate stocks). The present situation in KNP is characterized by reduced but continuing destructive fishing practices, primarily by non-Park inhabitants, and high pressure on demersal stocks like lobsters, shellfish, groupers and napoleon wrasse. Terrestrial threats include the increasing pressure on forest cover for fuelwood and water resources as the local human population has increased 800% over the past 60 years. In addition, the Timor deer population, the preferred prey source for the endangered Komodo dragon, is still being poached. Pollution inputs, ranging from raw sewage to chemicals, are increasing and may pose a major threat in the future.
1.2 PURPOSES AND OBJECTIVES OF THE KOMODO NATIONAL PARK
The goals for KNP are to protect its biodiversity (particularly the Komodo dragon) and the breeding stocks of commercial fishes for replenishment of surrounding fishing grounds. The main challenge is to reduce both threats to the resources and conflicts between incompatible activities.

1.2.2 Detailed Management Objectives
• Establishment of a strong co-management structure which is more self reliant for the Park. • Stop all destructive fishing practices, including compressor fishing, reef gleaning, etc.. • Protect fish stocks by closing all known fish spawning aggregation sites to fisheries. • Protect fish stocks by prohibiting demersal fishing in most areas of the Park. • Promote a shift of fishing effort from demersal to pelagic fishing. • Implement traditional use zones with exclusive fishing rights for Park inhabitants. • Implement reforestation and other rehabilitation efforts where appropriate. • Develop feasible methods to increase the rate of coral reef rehabilitation. • Introduce licensing system for all activities inside Komodo National Park. • Support members of local communities to enter in compatible enterprises. • Implement sustainable system for tourism management and Park financing. • Limit human population growth through restricting immigration and land use. • Stabilize the human population size within the Park. • Limit extraction of firewood and water resources, and provide alternatives. • Establish waste disposal systems and eliminate pollution inputs. • Eliminate dogs and cats and prohibit the introduction of other alien species. • Monitor populations of important species such as the Komodo dragon, the megapode, and the sea turtles and make management interventions as appropriate. • Maintain sufficient grazing habitat for deer.
1.3 TARGETS
KNP must protect the fauna, flora, and ecosystems found in the area, and support sustainable development within the region. Co-ordination is required with government agencies in the region, as well as with local communities, research institutions and NGOs. Specific targets include:
1.3.1 Protection
• Legal confirmation of the External Boundary System of the terrestrial and marine areas. • An operational zonation system in place, protecting all areas with high biological value. • An effective surveillance system implemented by motivated Park staff, to enforce regulations. • Park regulations are clear, enforceable, and ensure the protection of the natural resources. • Spawning locations for fish and other marine biota are preserved and maintain their functions. • The Park’s fauna and flora are protected and conserved in their natural habitats. • Limited harvesting activities do not threaten the populations of any species in the Park.
11
1.3.2 Conservation
• The Park’s flora and fauna are preserved in their natural ecosystems. • Effective management interventions are taken when species or eco-systems are threatened. • Animal migration routes in the KNP area are maintained in good quality. • Monitoring and evaluation systems are developed and effectively implemented. • Environmentally degraded areas are rehabilitated or restored as necessary.

2 SOCIO-ECONOMIC AND CULTURAL CONDITIONS
2.1 GENERAL POPULATION STATISTICS
2.1.1 Demographics
There are four villages located within the Park (Fig. 6). These are Komodo, Rinca, Kerora, and Papagaran. All villages existed prior to 1980 before the area was declared a national Park (Pagarang was included in the Park with the new borders of 1998, before that it was situated in the Buffer Zone of the Park). In 1928 there were only 30 people living in Komodo Village, and approximately 250 people on Rinca Island in 1930. The population increased rapidly, and by 1999, there were 281 families containing 1,169 people on Komodo, meaning that the local population had increased exponentially. Papagaran village is similar in size, with 258 families containing 1,078 people. As of 1999, Rinca’s population was 835, and Kerora contained 185 people. The total population currently living in the Park is approximately 3, 267 people. Approximately 16,816 people are living in the area immediately surrounding the Park.
KNP is located in Kecamatan Komodo, Kabupaten Manggarai NTT. An extension is planned into Kecamatan Sape, Kabupaten Bima, NTB. There are three desa inside the Park, desa Komodo, desa Pasir Panjang, and desa Papagaran. Before 1997, desa Papagaran was administratively under Desa Komodo and located in the buffer zone outside the Park. A revision of the Park boundaries in 1998 now includes Papagaran as a new desa within the boudaries. Komodo Village has had the highest population increase of the villages within KNP, mostly due to in-migration by people from Sape, Manggarai, Madura, and South Sulawesi. The number of buildings in Kampung Komodo has increased rapidly from 30 houses in 1958, to 194 houses in 1994, and 270 houses in 2000. In- migration in Rinca village has been primarily from Bima, Sape, Manggarai, Selayar and Ende. Kampung Kerora has the smallest population of the communities located within the Park.
There are several villages on the Park's east side in Kecamatan Komodo, on Flores Island, and on smaller islands. The villagers are mostly fishermen and are dependent on marine resources for their living. Desa Pasir Putih consists of two villages, Mesa Island and Seraya Besar Island. Labuan Bajo, Gorontalo, Warloka and Golomori are all located on Flores Island. Labuan Bajo and Gorontalo are part of the Labuan Bajo capital city of Kecamatan Komodo. In the last decade the population of Labuan Bajo has increased rapidly due to increased economic opportunities. Population growth was primarily caused by in-migration from South Sulawesi, Bima and Java. There are also a number of villages located on the west side of the Park in Kecamatan Sape, Kabupaten Bima, West Nusa Tenggara (Fig. 5). Bajau Pulau village is located on a small island and the other villages are located on the coast of Sumbawa. Communities in Bajau Pulau and Bugis are primarily composed of fisherman who use the Park's marine resources.
In 1993 the population size in Kecamatan Komodo was 29,077. This increased by 13.5% to 33,001 by the year 1997. The population size of Kecamatan Sape in 1993 was 71,355. As of 2000, the population had increased by 9.1% to 77,857. Many of the villages in and near the Park have shown greater increases in population size than the average increase observed within their Kecamatans. Kecamatan Komodo has shown a greater increase in population size than Kecamatan Sape. Labuan Bajo has the fastest growing population of the villages near the Park; and Komodo Village has the fastest growing population inside the Park area.

Figure 6. Villages in the Komodo area. Population numbers are based on a survey of population statistics by Komodo Field Office staff. The numbers pertain to 1999, or, if not available, to 1998 (Mesa, Labuan Bajo, Golomori, Warloka). For Gorontalo and Seraya Kecil, no separate statistics are collected (inhabitats are included in the statistic for Labuan Bajo). 14
2.1.2 Education
The average level of education in the villages of KNP is grade four of elementary school. There is an elementary school located in each of these villages, but new students are not recruited each year. On average, each village has four classes and four teachers. In Kecamatan Komodo there are three types of elementary school: Public Elementary (SD Negeri), Inpres Elementary, and Private Elementary (SD Swasta). Most of the children from the small islands in the Kecamatan Komodo (Komodo, Rinca, Kerora, Papagaran, Mesa) do not finish elementary school. Less than 10% of those which do graduate from elementary school will continue to high school. Children must be sent to Labuan Bajo to attend high school, but this is rarely done in fishermen’s families.
2.1.3 Health
Most of the villages located in and around the Park have few fresh water facilities available, if any, particularly during the dry season. Water quality declines during this time period and many people become ill. Malaria and diarrhea are rampant in the area. On Mesa island, with a population of around 1,500 people, there is no fresh water available. Fresh water is brought by boat in jerrycans from Labuan Bajo. Each family needs an average of Rp 100,000.- per month to buy fresh water (2000). Almost every village has a local medical facility with staff, and at least a paramedic. The quality of medical care facilities is low.
2.2 LOCAL ECONOMY
The majority of the people living within the Park and in the nearby adjacent areas rely on fishing as their main source of income (97%). The remainder are traders and civil servants. Some garden crops are planted near the villages, and woodland products such as tamarind are collected for sale. Agriculture is not an option for those living in the Park, as they have extemely limited access to land, the soils are poor and fresh water sources and rainfall are limited. In Sape, Sumbawa island, agriculture is used to supplement income from fishing. As educational levels are generally low, alternative economic opportunities are limited. Based on survey data gathered in the area by Sudibyo (Forestry Human Resources Development Agency) in 1995 and 2000, local fishing communities presently exhibit the following characteristics:
• Daily and seasonal incomes are highly variable. • The catch is perishable and has to be marketed quickly. • Large working capital is needed and high risks are involved. • Small share of profits for the fishers. • Traditional processing of marine products is of low quality.
2.2.1 Economically Important Species and Fishing Methods
The most valuable marine products harvested in the area are squid, live groupers, lobster, shrimp (terasi), sea cucumber, and nener (juvenile milky fish). The small pelagic lift net (‘bagan’) is the predominant gear type and the majority of the local fishing community derives its income from it. The bagan fishery primarily targets small schooling pelagic marine species, mainly squid. As catches of squid have been declining, scads and clupeid fishes, such as anchovies and sardines, have recently become more important in the bagan fishery.
15
At present more than 800 bagan fishing boats work in the area (Mesa: 100, Labuan Bajo: >150, Paparan: 150, Seraya: 10, Rinca: 5, Komodo: 200, Bajau Pulau: 100, plus others from Ende, and South Sulawesi). More diverse geartypes are used in the demersal fisheries (e.g., hookah compressor, hook and line, traps, gillnets). There are fewer of these geartypes present, but they are important economically. These geartypes are used in harvesting high value species such as lobsters and live reef fish (with hookah compressor, cyanide, hook and line and traps), and also allow large quantities of fish to be harvested in a short time span (with dynamite and gillnets).
2.2.2 Marine Productivity
Exploitation of the natural ecosystem in the Komodo National Park waters has increased and become more intensive over the past few decades. A cash economy has developed and the standard of living in the area has increased since 1980. This observation is based on the increasing number of people who have made the pilgrim’s journey to Mecca, and the growing number of boat owners, buildings, and televisions in the area. The use of destructive fishing practices, such as bombs and poisons, has increased with the increasing need for cash, and has had a negative impact on the Park’s quality as a source of replenishment.
Overfishing and fishing at spawning aggregation sites are severely straining the marine biota’s replacement capacity. Catch size has seriously declined for several species. Fishing activities need to be limited in order to sustain the ecosystem’s productivity. The Regency of Manggarai, in the Province of East Nusa Tenggara, and the Regency of Bima, in the Province of West Nusa Tenggara, have drawn up Space Utilization Plans for their respective areas of jurisdiction. These plans should be further develop with special attention for the marine areas.
2.3 SOCIO-CULTURAL AND ANTHROPOLOGIC CONDITIONS
2.3.1 Traditional Customs
Traditional communities in Komodo, Flores and Sumbawa have been subjected to outside influences and the influence of traditional customs is dwindling. Television, radio, and increased mobility have all played a part in accelerating the rate of change. There has been a steady influx of migrants into the area. At the moment nearly all villages consist of more than one ethnic group.
2.3.2 Institutions
Formal institutions of village administration include the Lembaga Musyawarah Desa (LMD) and the Lembaga Ketahanan Masyarakat Desa (LKMD). These institutions have not had a major influence on the dynamics of the village communities. In fishing villages the teachers usually come from outside, and many of the school-aged children do not attend school beyond the first few years. Government institutions provide technical support in the areas of agriculture, fisheries, health and family planning, but their programs have little impact on the dynamics of the fishing communities. Fishing cooperatives are rare. Economic institutions, such as banks and village unit cooperatives, are only present in a few locations and are not generally effective. Existing banks have primarily traders as their clients, and rarely advance credit to local fishermen. Investors and traders form influential informal institution in the dynamics of community development.
16
2.3.3 Religion
The majority of fishermen living in the villages in the vicinity of KNP are Muslims, and a strong, informal institution in this community is Koran recitation. Hajis have a strong influence in the dynamics of community development. Fishermen hailing from South Sulawesi (Bajau, Bugis) and Bima are mostly Moslems. The community from Manggarai are mostly Christians.
2.3.4 Anthropology and Language
There are several cultural sites within the Park, particularly on Komodo Island. These sites are not well documented, however, and there are many questions concerning the history of human inhabitance on the island, and the origins of stone megaliths. Outside the Park, in Warloka village on Flores, there is a Chinese trading post remnant of some interest. Archeological finds from this site have been looted in the recent past. Most communities in and around KNP can speak Bahasa Indonesia. Bajo language is the language used for daily communication in most communities.
2.4 IMPLICATIONS OF SOCIO-ECONOMIC AND SOCIO-CULTURAL ASPECTS
The human population within the Park is already over the carrying capacity of the area. The limited fresh water availability and the lack of appropriate soils for agriculture place limitations on population growth. Water is currently brought in from Flores and the local population has little access to fresh fruits and vegetables. Incentives (financial, social) need to be developed to attract people living in the Park to move to the adjacent larger islands (Flores, Sumbawa).
Education levels are still low, and there is little importance placed on higher education by members of the local communities. There are currently few incentives for education past elementary school, as the major economic opportunity (fishing) does not require extensive education. Given thee low educational levels, the perishability of the local fisheries produce, the relatively high levels of individual debt, and the control of the traders over setting purchase prices, it is difficult for fishermen and their families to improve their quality of life or increase the opportunities available to their children. Steps need to be taken to break the current cycle. An important first step would be to prevent traders from being both credit lenders and purchasers of marine products. The formation of fishing cooperatives, credit unions, and allowing fishermen to sell directly to the market would increase the profits obtained by the fishermen.
Cultural aspects are fluid and can change rapidly. New destructive fishing techniques have been adopted readily in the past, and have created major problems. Material expectations will rise exponentially in the next 25 years, as villagers are exposed to increased external inputs through tourists and television. The combination of increased material “wants” and the expansion of tie-ins into external markets will place a serious burden on Indonesia’s marine resources in the future. Extraction of marine resources will probably continue to be the main economic opportunity in the area over the next several decades. Careful management of these resources is necessary to maintain sufficient stock. Eco-tourism may provide some opportunities, but will probably not match the marine resource sector. Few of the revenues generated by tourism actually trickle down to the local villages. If education levels rise, there may be increased opportunities for economic diversification.

3. MAJOR THREATS TO THE NATURAL RESOURCES OF KNP
The Park is faced by numerous problems, both at land and on sea (Table 3.1), including:
• Human population pressure and increased demand on natural resources are leading to degradation of both the terrestrial and marine resources. • Destructive fishing practices in the area are the single largest threat to the marine resources. • Overharvesting of marine resources, particularly demersal species, is a major problem. • The introduction of non-native species, including dogs, cats, and goats, pose a risk to threatened endemic species through the introduction of disease, predation, or competition. • Pollution inputs are increasing due to lack of appropriate waste disposal methods for sewage and trash, oil/fuel spills in marine environment, and runoff from fertilizers and pesticides. • The current terrestrial habitat is heavily influenced by past anthropogenic activities. Fire, both deliberately lit by poachers, and accidental, is a major threat to forest habitat. • The poaching of deer, turtle eggs, fruit bats, nests of cave swiftlets, etc. is still rampant. • Global warming could pose a significant threat to the area in the future.
3.1 HUMAN POPULATION PRESSURE
The human population within the Park borders has increased approximately 1,000% since 1930. High birth rates and immigration rates have both contributed to the problem. The constantly rising population places increasing demands on the resources, including fresh water, fuelwood, and building materials. The pressure is leading to degradation of the terrestrial resource base. The collection of firewood from the mangroves and surrounding forests degrades them, and leads to the loss of breeding grounds and shelter for marine life and terrestrial species, the loss of windbreaks, increased erosion / siltation, and the loss of food sources for some species. Increased extraction / diversion of water leads to reduced water available for dependent fauna, changes in the water table, and will affect plant distribution patterns.
3.2 DESTRUCTIVE FISHERIES
3.2.1 Fishing with Explosives
Fish bombs are mostly made with artificial (chemical) fertilizers such as ammonium- and potassium nitrate (NH4NO3; KNO3), which is mixed with kerosene in a bottle. Blast fishers hunt specifically for schooling reef fish, so that only a few bombs will assure a relatively large catch. After the charge explodes, diving fishers enter the water to collect the fish, which have been killed or stunned by the shock-wave from the explosion. The size of the coral area destroyed by a single blast is dependent upon the size of the bomb and the position of the explosion relative to the coral reef. A beer bottle bomb will shatter an area of stony corals approximately 5 m in diameter. Many blast fishing operations use "hookah" compressors to collect their catch from the reef. Blast fishing is considered one of the most destructive anthropogenic threats to coral reef ecosystems. It destroys the reef structure, eliminating its ability to provide food and shelter to marine organisms, and protect coastlines. It directly and indiscriminately kills the fish and invertebrates that inhabit the reef. In addition, reef-related tourism, which holds great promise for alternative income generation, can not be developed in areas that are being blasted.

3.2.2 Fishing with Cyanide
Cyanide solutions are used extensively to catch live reef fish for consumption and ornamental purposes. The concentrations of dissolved poison are not meant to kill but only to tranquilize the target fish, which facilitates their capture. The live food-fish trade concentrates on the catch of groupers and Napoleon wrasse. The aquarium fish trade concentrates on a much wider variety of species of colorful reef fishes. Live spiny lobsters, are also caught with cyanide. Cyanide fishing is done by divers, using "hookah" compressors and hoses to supply air. A diver on a "hookah" compressor-hose descends 10-40 meters until he spots a target fish. He chases the fish into a crevice in the reef and then squirts cyanide from a plastic bottle into the hole. As the fish begins to weaken, the diver breaks away the coral around the hole, reaches in, grabs the fish, and slowly escorts it to the surface. The cyanide fishery for aquarium fish destroys large areas of corals, which are broken down after an area has been sprayed with cyanide and the target fishes have fled in between the corals. The use of hookah compressors is a key factor in cyanide fishing practices.
3.2.3 Reef Gleaning for Invertebrates by Breaking down Corals (‘Meting’)
The fishery for abalone (mata tuju) has destroyed large areas of coral reefs in recent years. While dynamite and cyanide fishing are becoming less of a threat to these reefs, many fishermen are digging through the reefs, using compressors and steel bar tools (the method is called 'meting'), in search of abalone and other marine invertebrates. The fishermen break down and turn over the corals (which are also trampled by them in the process) and leave behind them fields of near 100% dead coral rubble. Collecting invertebrates from reef flats is a traditional activity, which used to be focused on sea cucumber and carried out during very low tides. The high price for abalone and the availability of dive gear and 'hooka' compressors changed this into a more serious activity in the early nineties and initiated an increase in the total applied effort.
3.2.4 Fishing with Natural Poisons, Herbicides and Pesticides
A traditional fish poison which is used on the coral reefs of KNP is called 'tuba', which is a powder made from the seeds of trees. The powder of the grounded seeds is mixed with water, which is then spread out mainly over sea grass beds to catch rabbitfish (Siganidae). The fish are reportedly only stunned by the poison and do not die of it. Stunned fish are collected for local consumption and dried for sale on local markets. Reefs around northern Rinca and Papagaran are major target areas. This method is reportedly widespread and about 60% of all fishermen in the area use 'tuba' every now and then. Since natural poison is not always easy to obtain and less effective than artificial chemicals, fishermen from the area between Komodo and Labuan Bajo have started using herbicides and pesticides which they still call 'tuba'. Herbicides and pesticides are cheap and readily available, and therefore popular in catching a variety of small reef fish.
3.2.5 Fishing with Traps (Bubu), Hook and Line and Gillnets
The use of bamboo mesh traps (bubu) is widespread in Indonesian reef fisheries. The process of setting and retrieving the trap is responsible for extensive destruction on the reef. To hide the traps in the reef, divers break off live coral to cover them. Traps set by simply lowering the trap from boatside via a buoyed rope are responsible for even more serious reef damage. These traps are often heavily weighted, and can destroy entire stands of corals during their installation.
20
The main non-bagan yield category from KNP is fish (almost 95%). These fish are mostly caught by gillnets, and by trolling and bottom hook and lines. Demersal trolling lines or 'kedo kedo' are wiping out the coral trout stocks. Bottom hook and lines take all predators and bottom longlines are decimating the sharks and large groupers. Gillnets kill indiscriminately, including turtles, dugong, cetaceans, and all species of reef fish. The fish stocks of the Park are seriously threatened by the use of gillnets and bottom longlines.
3.3 OVER-HARVESTING
The target fish species in the live reef fish trade commonly aggregate at specific sites to spawn. Groupers and Napoleon wrasse migrate many miles each season to these spawning sites. Spawning aggregation sites are extremely vulnerable since experienced fishers are skilled in locating them. Wiping out the fish on one aggregation site equals the elimination of top predators from several square miles of reef. Grouper and Napoleon wrasse spawning aggregation sites therefore need to be protected wherever possible.
Mangroves, seagrass, lontar palms, and other species have been overharvested in the past. Seagrass is collected for use as a food source and as an ingredient for cosmetics. There is a large external market for these products. Mangrove tress are used for fire wood. The palm trees are used to make furniture and buildings locally. The decrease in the seagrass population may lead to increased coral mortality and decreases in species dependent upon them for shelter and food.
3.4 EXOTICS
A number of exotic species have been introduced in KNP. The introduction of non-native species, including dogs, cats, and goats, pose a risk to threatened endemic species through the introduction of disease, predation, or outcompeting local species for resources. Feral dogs (along with poaching) reportedly helped cause a local extinction of Timor deer in the mid-70’s on Padar Island. The introduction of alien exotics may lead to local extinctions of deer, dragons, Rattus rintjanus, megapodes, endemic plants and the collapse of food webs.
3.5 POLLUTION
Pollution inputs are increasing due to lack of appropriate waste disposal methods for sewage and trash by local communities, oil and fuel spills in the marine environment, and runoff from fertilizers and pesticides. Nutrient inputs from sewage and fertilizers can lead to algae blooms offshore causing large scale dieoffs of marine biota. Oil and fuel spills can kill off coral. Chemical spills and pesticides can rapidly decimate marine communities. Turtles and cetaceans are particularly vulnerable to plastic wastes, often ingesting them or getting entangled in them.
3.6 TOURISM
Tourism increased significantly until 1997. As of 1996, the Park was receiving 30,000 visitors per year, and this figure was growing at 11% per year. Although numbers fell during the economic crisis in 1997-1999, visitation is expected to rise again. This places additional demands on the natural resources, and increases sewage and trash inputs. Marine recreation can damage coral reefs (inappropriate contact or anchor damage) and disturb spawning and nesting sites.
21
3.7 POACHING
The poaching of deer, turtle eggs, fruit bats, nests of cave swiftlets, etc. has been an on-going problem for the area. Poaching may lead to local species extinctions, e.g., a decrease in the deer or other prey species population could lead to loss of the entire population of Komodo dragons. A decrease in the swiftlet or bat population could cause an increase in the insect population, and higher probability of disease transmission by mosquito vectors (e.g., malaria and dengue fever).
3.8 EL NINO – LA NINA WEATHER PATTERNS
El Nino- La Nina events appear to be occurring on a three to five year cycle at present. The severity of the event varies. Warming of oceanic waters causes coral bleaching and mortality, although due to the upwelling of cool water, the corals in the Park have not been strongly affected in the past. Long droughts lead to increased risk of fire and vegetation mortality.
3.9 GLOBAL WARMING
Global warming could pose a significant threat to the area in the future. Ocean levels are currently rising as the ice at the earth’s poles melt. Islands could become significantly smaller due to rising sea levels. Coral reefs in the Park are particularly vulnerable to rises in mean water temperature, and could suffer increased mortality through coral bleaching. Only the cold water upwelling along the Southern shores of the Park protected the corals against bleaching in 1998.
3.10 OTHER THREATS:
The islands are volcanic in origin and there are active volcanoes in the region. In addition, there is a lot of seismic activity throughout Indonesia. Volcanic eruptions, earthquakes, or tsunamis could cause damage to coral reefs and terrestrial habitats. This could lead to local population extinctions in the immediate area affected.
3.11 IMPLICATIONS FOR MANAGEMENT
The conservation of the Komodo dragon and its habitat is the most important management consideration for KNP. The most important considerations for the marine component are the maintenance of diversity and marine productivity. Local communities are dependent upon the fisheries supported by the Park to make a living, but destructive fishing practices threaten their livelihoods. Preliminary data show that intensive patrolling is an effective measure to decrease dynamite fishing, but cyanide fishing has been difficult to ban. Profit margins in the cyanide fisheries are large enough to allow for very large bribes. Steps to improve enforcement and improve co-management should be undertaken immediately together with local government.
The Park's fish resources will soon be depleted if the area is not truely protected. The fishing pressure on the reefs is high and increasing and this needs to be reversed in order to achieve the objectives of the Park. Demersal fishing effort in the Park needs to be greatly reduced. Access to marine resources in the KNP and buffer zone should be limited. Preliminary data clearly show that it is communities from outside the Park that are having the most damaging impact. Exclusive use rights for local communities should be established in selected Traditional Use Zones, and spawning aggregation sites in the Park should be closed for all fishing activity.
22
4. MANAGING THE PARK’S NATURAL RESOURCES
4.1 MANAGEMENT OPTIONS
Management tools to deal with threats include biological and ecological tools, such as area rehabilitation, habitat improvement, translocation, culling of exotics, disease control, etc. Anthropogenic threats can be managed through zonation, regulations, law enforcement, education, and alternative economic development, among others. The decision as to which tools are appropriate should be based on a number of factors, including the ecological consequences, feasibility, probability of success, and cost. These decisions often can not be made alone, but require input from other sources, including experts, the District Government and local communities. Management options for KNP include:
• Strengthening cross-sectoral enforcement and coordination. • Implementation of a long-term biological monitoring program. • Implementation of a long-term monitoring program on resource use. • Implementation of zonation and clear regulations. • Improvement of tourism and tourism-revenue management. • A ban on hookah compressors and other destructive gear types. • Development of user-friendly loan systems for fishers to reduce dependence on middlemen. • Focused dialogue with specific problem groups or communities. • Implementation of exclusive use rights for Park inhabitants. • Complete protection of spawning aggregation sites within established no-take zones. • Development of compatible and profitable economic activities. • Implementation of comprehensive awareness and education campaigns.
4.1.1 Co-Management with the Provincial Government and Local Communities
The relationship between protected areas, government agencies and local communities is a key factor for the long-term conservation of natural habitats and resources in and around these areas. For the local government and communities to become effective partners in co-management of the Park, it will be necessary to provide them the information and skills needed to make appropriate decisions on environmental matters. Government and community members need to be fully informed and aware of the environmental impacts of the activities in which they and others engage. In order to implement a co-management approach, it will be necessary to create new structures. At a minimum, these structures include a Collaborative Management Board, a Collaborative Tourism Council, and a Community Stakeholder Board. Input from all stakeholders will be obtained through these Boards and Councils in a formalized manner.
Specific attention needs to be given to the two district governments (Manggarai and Bima) to make sure that all activities are coordinated. Co-management sytems have to be implemented with the local governments which are responsible for the management of surrounding towns, such as Labuan Bajo, Sape and Bima. These towns function as the nearest base of visitor flows to the Park. In themselves those towns may develop as tourism centers. The local governements should pay special attention to the development of their towns, which have to fit in the overall plan of Park development, especially if they want to derive optimum benefits from the Park’s visitors.
23
The Park authorities have numerous responsibilities and obligations. To ensure the effective and efficient running of the Park it may be necessary to privatize certain functions, such as tourism management. This will help provide sufficient resources to carry out all necessary management activities and ensure a high level of professionalism.
As the Park contains terrestrial, marine and coastal components, it necessitates the involvement of numerous ministries and government agencies. In addition, the coordination of all pertinent agencies allows for better integration of terrestrial and marine ecosystem management. The activities of the Ministry of Marine Exploration, the Ministry of Finance, the Ministry of Settlements, the State Ministry of Environment, the Ministry of Regional Planning, the Ministry of Internal Affairs, the Ministry of Transportation, the Ministry of Communication, the Navy, the Ministry of Agriculture, the Governor of NTT, the Governor of NTB, the District Heads of Manggarai and Bima, all need to be coordinated with the Ministry of Forestry and Estate Crops.
4.1.2 Adaptive Management
Maintaining ecological systems and ensuring the long-term sustainable use of economic and threatened species is dependent upon making appropriate responses. The ability to make appropriate responses is limited by the available information. Monitoring activities have been undertaken within KNP to supply the data necessary to evaluate the effectiveness of management measures and to make decisions on adjustments in regulations or in the management strategy. KNP should adopt an adaptive management strategy, modifying management regulations and interventions based on new information from the field. Effective management of the Park’s resources requires information on the distribution, size, composition and growth trends of terrestrial and marine species. In the following section, suggested data collection methods are described. Environmental variables have not previously been measured on a regular schedule and should be included in a regular data collection program. Although some terrestrial data have been collected, there is no standardized terrestrial data collection protocol yet.
4.2 BIOLOGICAL MONITORING AND EVALUATION
4.2.1 Terrestrial Animal Censuses
Line census transects should be established, with each transect measured using a meter tape, making slope adjustment corrections if necessary. Transects should be approximately 2 km in length. Separate censuses should be made for arboreal animals (small Komodo dragons) and terrestrial animals (Komodo dragon, deer, water buffalo, horses, pigs, turtles and scrubfowl). Trail order and census type should be randomized. Early morning censuses should begin after dawn and late afternoon censuses should begin at approximately 15:30 P.M.
Animal densities should be calculated based on total area censused. The total area censused is equal to the number of surveys per trail multiplied by the length of the trail and the detection strip width. The detection strip width varies across species, and should be calculated based on the average distance to detection (perpendicular distance from the trail to the animal) if the animal is heard or seen. Use indices have to be calculated for trace measures. Comparisons of data sets between years should be made in order to identify trends in population growth and composition. These data should be used in modifying Park management procedures.
24
4.2.2 Vegetation Monitoring
Permanent vegetation plots should be placed in different habitats (mangrove forest, savanna, monsoon forest, quasi-cloud forest). All trees over 10 cm DBH should be identified if possible and given unique identification numbers with permanent tags. Aluminum tags should be affixed using small aluminum nails. Plot size, shape, number, and location should be determined by a professional ecologist, based on the degree of diversity in an area and logistical and financial constraints. For statistical purposes, at least five plots should be made in each habitat type. These plots should be monitored once per year to obtain mortality, recruitment, and growth rates.
Overall distribution and size of the major vegetation types need to be monitored on a yearly basis. This can be done through the use of Landsat or aerial photographs, aerial transects, or on the ground walking along habitat edges with a GPS. All data collected should be entered into a GIS system to make comparisons across years. Succession of savanna to forest, in particular, needs to be monitored, as the Komodo dragon’s prey species are dependent upon the presence of savanna.
4.2.3 Environmental Monitoring
Environmental factors directly affect vegetation growth and animal activity levels, and play a major role in distribution and diversity patterns. Climate should be monitored daily. The minimum and maximum temperature and humidity levels should be recorded from weather stations placed in different habitats (mangrove forest, savanna, monsoon forest, quasi-cloud forest) on Komodo and Rinca. Total rainfall should be measured from rain gauges placed in open clearings. Water quality (marine and freshwater) should be assessed on a regular basis. Simple chemettes test kits can be obtained to use for monitoring gross trends.
Overall environmental quality can be assessed through the presence / absence (one-zero sampling) of simple indicators along transects. These include humidity indicators (moss or lichen, epiphytes, hanging or bole vines) and disturbance indicators (cut trees, machete marks, trash or other anthropogenic traces), as well as canopy and ground cover, tree sizes, tree density, etc. Quality is assessed relative to other areas of the same habitat type that are known to be of high quality, and comparisons can also be made across years for the same transects. A professional ecologist should set up protocols for environmental monitoring.
4.2.4 Coral Reef Monitoring
An on-going coral reef monitoring program provides information on spatial and temporal patterns in reef status and reef rehabilitation inside and outside the Park, with particular focus given to changes in the percentage of damaged coral. An intensive survey of the coral reefs (185 locations, see also Fig. 7) made every two years, enables mapping of damage by destructive fishing methods and other causes. This information provides feedback on the effects of management measures and on the rehabilitation of the reefs. All sampling sites have coral reefs and range in depth from 4 to 12 meters. All sites are surveyed by snorkeling (at 4 m deep) and by SCUBA diving (at 8 m and at 12 m deep). Five observations are made at each depth and each observation lasts four minutes. After each four minute swim, the observer records the estimated percentages (minimum step size 5%) of four habitat categories (totaling 100%):
25 Coral Monitoring Sites
shallow (< 20 m depth) reef flats
Figure 7. The 185 sites of the coral monitoring program. At each site, bottom coverage of 4 categories (live hard coral, dead hard coral, soft coral and others) is visually estimated at three depths (4, 8 and 12 m).
26
• hard coral live, • hard coral dead, • soft coral, • other (rock, sand, sponges, tunicates, algae, weeds, anemones, clams, etc.)
For each dive or snorkel-swim, the following information is recorded on the standard (UW) data sheets: date, site number, location (GPS), depth and name of observer. The current data collection schedule is 12 sites per week, two (or more) coral reef monitoring weeks each month, and at least 24 sites covered each month. The total survey takes approximately 8 to 9 months. For the 185 sites, approximately 2775 observations on reef status are made over each 2 year period. A hard coral mortality coefficient is calculated for each site.
The mean percentages of all habitat categories and the mean mortality coefficients are calculated larger areas, which are assumed to have different environmental conditions and different levels of impact from the fisheries. Means over areas are calculated using as input the means over complete swims that include 5 observations each. For statistical analysis these means are arcsine transformed (%), after which an analysis of variance is used to calculate the levels of statistical significance of differences over time.
Based on preliminary data, coral recovery was greater outside the Park than within the Park. Overall destruction of the coral reefs in and around KNP appears to have stopped as of 1996 and a slow recovery (2% increase in hard coral cover per year) has started. This is most likely the result of the enormous decline in dynamite fishing in the area since early 1996. Reef recovery is fastest near the center of protective activity, which is in the town of Labuan Bajo, outside Park boundaries. Recovery is generally slower inside the Park, where many remote areas are still difficult to control. Potential management responses to monitoring results include:
• Revision of KNP regulations and zonation designations as necessary to reflect the impact of use activities on the coral reef and eliminate or reduce damage (e.g., allocation of specific sites for dive-tourism, artisanal fisheries, full protection, or other purposes.), • adjustment of the enforcement program in terms of effort allocation in space and/or time (adjustment of surveillance routine) to protect areas at risk, and • identification of locations and implementation of activities at places where active management is needed for reef rehabilitation.
4.2.5 Grouper and Napoleon Wrasse Spawning Aggregation Sites
Grouper and Napoleon Wrasses spawning aggregation sites (Fig. 8) are being monitored to provide information on trends in the populations of economically important fish species, and to obtain feedback on the effects of management activities. The current fish monitoring program focuses on 12 key species out of two families: the Serranidae (groupers) and the Labridae (wrasses). These species have been heavily targeted by the commercial fisheries and can therefore serve as indicators for the impact of these fisheries. Data are collected to a) determine if and how fish populations are changing over time and in space and b) identify spawning locations and spawning seasons for key fish species. Potential management responses include adjustment of zoning and regulations for fisheries and other activities.

(bottom, moon Figure 8
The 12 species in the fish monitoring program are: 1) Epinephelus tukula, 2) E. polyphekadion, 3) E. fuscoguttatus, 4) E. malabaricus, 5) E. chlorostigma, 6) Plectropomus leopardus, 7) P. laevis, 8) P. areolatus, 9) P. oligocanthus, 10) Variola louti, 11) Cromileptes altivelis and 12) Cheilinus undulatus. For these 12 target species, numbers and sizes are recorded in cm standard length at selected sampling sites. Spawning behavior is recorded as occurrence of one or more of seven "spawning signs" (types of behavior):
1. Grouping of fish in clusters more dense than normal. 2. Frequent male-male aggression and fighting. 3. Coloration not seen at other times or locations. 4. Female bellies becoming highly visibly swollen. 5. Unusual marks or behavior typical for spawning aggregations 6. Pronounced side to side waggling/quivering/shimmying by males. 7. Actual spawning.
The fish monitoring program is a continuous program with monitoring activities taking place twice every month. Spawning sites were chosen as sampling sites based on the following criteria: representative numbers of target species were likely to be observed, and recorded numbers and sizes could effectively be followed over time and in space. Since March 1998, six sites have been monitored twice a month, once during new moon and once during full moon. Each site is searched for target fish at a specific depth profile, which has been established for that site.
Preliminary results indicate that different species spawn at different lunar phases. Only two grouper aggregation sites, one with mainly E. fuscoguttatus and one with mainly P. areolatus, have been identified within the borders of Knp, although hundreds of sites have been surveyed. Spawning seasons and timing in the lunar phases have been identified for most important species in Komodo. The main spawning season for target species is from October to January (Fig. 8), with small differences between species. Different species use the spawning sites at different moon phases and many other reef species, including important food and ornamental fishes use the same spawning sites. All spawning sites have strong currents directed away from the reef.
Fishermen supplying the live reef fish trade all target the spawning sites in Komodo National Park. If fishermen identify the aggregation sites and the sites are not protected effectively, they will probably be fished out within 1 or 2 seasons. The few sites with spawning populations of the main target species in the live reef fish trade are of great importance to KNP’s function as a source of recruits for surrounding fishing grounds. The spawning sites in the Park need to be fully protected and therefore need to be embedded well within the borders of the no-take zones.
4.2.6 Diversity and Abundance of Cetaceans
A cetacean survey program should be an integral component of the marine resources management strategy in KNP. No detailed studies have been done in these waters on cetacean (whales and dolphins) species diversity, abundance and distribution. A preliminary review of cetaceans sighted in Indonesian waters lists 29 species. Data on cetaceans are especially important when considering the complex regional oceanography. Indonesia is uniquely located as the only equatorial region worldwide where inter-oceanic exchange of marine flora and fauna occurs. Cetacean movements between the Pacific and Indian Oceans occurs through the passages between the Lesser Sunda Islands which span over 900 km between the Sunda and Sahul shelves.
29
The ecological significance of these passages remains poorly understood, yet their importance as migration corridors is highly probable. Migratory cetaceans which include these passages in their local or long-range movements (Fig. 4) are vulnerable to numerous environmental impacts such as habitat destruction, subsurface noise disturbances, net entanglement, marine pollution and over fishing of marine resources. Most, if not all, of these impacts occur in the waters of KNP. These impacts would affect residential populations as well as transient species that include the passages in their migration. Cetacean surveys were carried out in and around KNP in the late 90’s, but it is important to continue periodic visual and acoustic monitoring in the Park and adjacent waters to:
• identify which cetacean species occur in these waters, • monitor seasonal patterns in KNP cetacean distribution and abundance, • examine effects of environmental impacts on cetaceans, • determine whether the waters of KNP include sensitive marine areas for cetaceans such as preferred feeding grounds, mating and calving locations, and migration corridors, • provide site-specific information on cetaceans for educational and awareness programs, and • Initiate a cetacean sighting program for tourism purposes.
4.2.7 Oceanography
Prevailing current patterns in and around KNP should be documented. If insufficient information is available from the literature, primary data collection should be initiated. These data are needed to predict the dispersal patterns of larvae of coral reef organisms to surrounding areas, and thus assess the effects of KNP management on recruitment processes in adjacent fishing grounds.
4.2.8 Seagrass Beds
Preliminary surveys on species distribution has been carried out in seagrass ecosystems in KNP (Fig. 3). Species diversity is high and several commercially important species are present. A series of underwater transects should be established for monitoring of seagrass beds. Transects should be marked using permanent markers (rebar stakes) or natural markers, if available. Equal numbers of transects should be randomly located within a) existing seagrass beds, b) adjacent areas without seagrass, and c) remote areas without seagrass. Exact transect numbers, locations, lengths and shapes should be determined, based on the degree of diversity in the area, and logistical and financial constraints. Cover, species abundance and diversity should be measured, using point sampling or fixed area sampling. These plots should be monitored every three months to obtain data on mortality, recruitment, growth rates, and changes in population size.
4.3 GENERAL MANAGEMENT ISSUES
4.3.1 Area Rehabilitation and Conservation
Several specific terrestrial and marine habitats within the Park have been severely degraded. Approximately 150 km2 or 25% of the terrestrial ecosystem of KNP has been severely degraded by fire and the poaching of lontar palms. All mangrove habitat present has been damaged in the search for fuelwood by local residents. Large parts of the coral reefs have been damaged by destructive fisheries practices, including bombing and cyanide fishing.

Research and monitoring should be undertaken to document the natural succession patterns in the savanna, mangrove, and coral reef eco-systems, before rehabilitation activities are carried out. The location, techniques, and species of interest should be identified based on the pilot studies. Rehabilitation can be undertaken in any zone if deemed necessary by Park management. This will require training in appropriate techniques, human resources, and financial inputs.
Reforestation Restoration efforts should only be undertaken in severely degraded areas, unlikely to return their original condition without intervention. Only native species should be planted, and efforts should be made to mimic naturally occurring succession patterns and species associations. If possible, seedlings should be obtained from adjacent areas, to ensure that the seedlings are adapted to the site. Planting regimes should be based on the best available data, and pilot studies should be undertaken prior to any large-scale efforts.
Coral Reef Restoration Restoration efforts should only be undertaken in severely degraded areas, unlikely to return to their original condition without intervention. These include areas where there is a strong current and no hard substrate. Preliminary data indicate that the provision of hard substrate in damaged areas greatly increases the rate of coral recovery. Restoration regimes should be based on the best available data, and pilot studies should be undertaken prior to any large-scale efforts. If possible, local people should be hired to do the work.
Soil Conservation The majority of the soils are quite fragile and subject to erosion when exposed. Ground cover should be maintained. Trail development should take into account the probability of erosion, and trails should not be placed near river or stream beds. Runoff to rivers and streams should be minimized. Development activities in the settlement zones should take erosion into account, and all efforts should be made to conserve soils.
Forest fire There is a high risk of fire on a regular basis on all the islands. This is due to the dominance of grasses (fire-adapted species) which dry out quickly and provide fuel, a long dry season, and high temperatures. The major threat from fires is not to the savanna, which is in fact dependent on fire to maintain it, but to the adjacent forest. If these forests are degraded, they are much more vulnerable to the invasion of fire. Fire plans should be drawn up containing information on the nearest water sources, usual wind patterns, topography and location of vegetation types. Maps should indicate the best places to install fire breaks. Rangers and villagers should be trained in fire fighting techniques. Fire fighting equipment should be kept ready (chainsaws, shovels, water backpacks, face masks) and regular patrols should be made.
4.3.2 Individual Species Management
Specific threatened or rare species of interest may require active management interventions on occasion to ensure their survival and well-being. Careful assessments should always be made in advance, and advice from experts should be solicited. These interventions include relocation or translocation, rehabilitation, and habitat changes.
Species relocation

Given the small population sizes of Komodo dragons and their primary prey species, Timor deer, local extinctions and inbreeding depression may occur. It may be necessary to actively manage these species through translocation or reintroduction of specific individuals. As translocation poses many risks to the remaining target population (e.g., disease), this should be only undertaken as a measure of last resort, as natural restocking may occur from adjacent islands. Reintroductions should only be undertaken if the probability of natural restocking is very low. Prior to any reintroduction or translocation, a population assessment should be made of both the source and target population. Individuals selected for translocation or re-introduction should be in good health, and their removal should not have a negative impact on the survival of the source population. The social structure of the source and target population should be kept in mind. In addition, there are genetic considerations. Rinca Komodo dragons are more closely related to the Flores population than the population on Komodo Island. As Padar Island is close to Rinca Island, any re- introductions would need to be from Rinca, not Komodo.
Disease The risk to individual plant species from plant diseases is low, given that agricultural activities are not common in the area. Areas degraded by pollution or logging, however, are less disease resistant. The mangrove forests are most at risk as they are the most degraded. Humans pose a threat to the long-tailed macaques, as they are susceptible to human diseases, such as respiratory infections and malaria. As they can also act as the vector for transmission of malaria, monkeys should not be kept as domestic pets. Domestic animals, particularly dogs, cats, and goats, can carry diseases and transmit them to the wild mammals (e.g., rabies, distemper).
4.4 RESOURCE USE PATTERNS
The determination of resource use patterns is essential to good Park management. Fishermen working in and around KNP use a variety of fishing techniques and equipment. Some methods and types of equipment are destructive and degrade the Park’s resources. The threat of illegal destructive fishing methods is a major problem, which needs to be addressed in order to protect the marine habitats of KNP. A patrolling program was started on 28 May 1996, with TNC and KNP staff trained to record data on resource use.
4.4.1 Monitoring of Marine Resource Utilization
The objective of this monitoring program is to determine which community groups are involved in which fishing activities, where they fish, and when they fish. Over time these data will also show any changes in the behavior of fishermen due to management measures and it will indicate which groups of fishermen or areas in the Park may need extra attention. Each non-bagan (non-lift net) fishing vessel or fishing group encountered during the routine patrols is investigated, except. bagans (the local pelagic lift-net), which are excluded since they operate only at night (with lights) and they form a separate type of pelagic fishery which is not currently considered threatening to the demersal and sedentary marine resources of KNP. Bagan is the most important geartype used in the Park and accounts for the major part of fishing revenues. Bagan boats are investigated whenever they engage in non-bagan activities during the day. All non-bagan activities are investigated since they are considered potentially threatening to the demersal and sedentary marine resources in KNP. Data collected from fishing vessels encountered during patrols include:
• date and position (using GPS coordinates), • type of boat and engine according to categories, 32
• number of fishermen on the boat or in the fishing group, • method or fishing gear according to categories, • species in the catch according to categories, • quantity and quality of the catch according to categories, and • origin of the fishing vessel or group according to categories.
4.4.2 Marine Resource Use – Management Implications
The routine patrolling program has led to a significant decline in destructive fishing practices, and should be maintained. The primary threat comes from outside communities in Sape, South Flores and Sulawesi (Fig. 9). Local communities pose less of a threat, since they generally use 'bagan' lift- nets that are not destructive to the coral reef ecosystem. The bagan fishery of local communities should also be monitored in the future, to avoid overfishing and collapse of stocks of small pelagics.
Important threats to the coral reef ecosystem include the use of hookah compressors in combination with dynamite and cyanide. Demersal trolling lines or 'kedo kedo' are wiping out the coral trout stocks. Bottom hook and lines take all predators, and bottom longlines are decimating the sharks and large groupers. Gillnets catch the largest volume of fish in the Park (Fig. 10) and are a threat to many species, including turtles and marine mammals. At minimum, management responses should include:
• Appropriate zoning and implementation of regulations that achieve management objectives with a minimum of conflict with local resource users (e.g., local exlusive use rights), • Targeting enforcement efforts and alternative livelihood programs on the fishing groups and communities that pose the greatest threats to the Park, • Prohibition of fishing activities threatening the Park’s coral reefs and demersal species, • A ban on hookah compressors and other destructive gear types, and • Complete protection of spawning aggregation sites within no-take zones of the Park.
4.5 RESEARCH
The KNP authorities should support applied research programs related to management of the Park. KNP should work with partners from research institutes and study subjects should include:
• reproductive biology of the Komodo dragon, • the economy of destructive fishing practices, • monitoring of coral reef degradation and rehabilitation in KNP, • rehabilitation of coral reefs through manipulation of coral reef substrate, • grouper and Napoleon wrasse spawning behavior and aggregations, • resource use of coral reefs and consequences for protected area management, • the function of marine protected areas in coral reef fisheries management, • environmental impact of alternative economic activities near protected areas, • the relationship between economic factors, resource use and quality of life, and • the relationship between sociocultural factors and environmental quality.
