PhytoKeys 23: 1–17. doi: 10.3897/phytokeys.23.4752 Abstract A checklist of the flora of Chad has been compiled by the authors, based on literature, on-line data-bases, herbarium collections and land surveys (1998-2011). It counts 2,460 records, i.e. 2,288 species (including 128 autonyms), 83 subspecies, 81 varieties, 8 forms, while all the previous available information reported 1,600 species. They belong to 151 Families, with 48.7% of the taxa belonging to the 6 largest families, i.e. Poaceae (14.6%), Fabaceae (13.6%), Cyperaceae (7.0%), Asteraceae (6.2 %), Malvaceae (3.9%) and Rubiaceae (3.4%). A total number or 2,173 species (88.3%) are native to Chad, including 55 (2.2%) endemic species, while 274 (11.0%) are alien to Chad, and 13 (0.5%) are considered cryptogenic, i.e. of uncertain status. It represents a considerable update on previous knowledge on the alien flora of Chad that counted for 131 taxa (5.3%). -
Plant Common Name Scientific Name Description of Plant Picture of Plant
Plant common name Description of Plant Picture of Plant Scientific name Strangler Fig The Strangler Fig begins life as a small vine-like plant Ficus thonningii that climbs the nearest large tree and then thickens, produces a branching set of buttressing aerial roots, and strangles its host tree. An easy way to tell the difference between Strangle Figs and other common figs is that the bottom half of the Strangler is gnarled and twisted where it used to be attached to its host, the upper half smooth. A common tree on kopjes and along rivers in Serengeti; two massive Fig trees near Serengeti; the "Tree Where Man was Born" in southern Loliondo, and the "Ancestor Tree" near Endulin, in Ngorongoro are significant for the local Maasai peoples. Wild Date Palm Palms are monocotyledons, the veins in their leaves Phoenix reclinata are parallel and unbranched, and are thus relatives of grasses, lilies, bananas and orchids. The wild Date Palm is the most common of the native palm trees, occurring along rivers and in swamps. The fruits are edible, though horrible tasting, while the thick, sugary sap is made into Palm wine. The tree offers a pleasant, softly rustling, fragrant-smelling shade; the sort of shade you will need to rest in if you try the wine. Candelabra The Candelabra tree is a common tree in the western Euphorbia and Northern parts of Serengeti. Like all Euphorbias, Euphorbia the Candelabra breaks easily and is full of white, candelabrum extremely toxic latex. One drop of this latex can blind or burn the skin. -
Fire Along the Transition Between the Amazon Forest and Cerrado
Fire Along the Transition Between the Amazon Forest and the Cerrado Ecosystems1 Gustavo Hees de Negreiros23, David Sandberg4, Ernesto Alvarado5, Thomas Hinckley4, Daniel C. Nepstad6, and Marcos Pereira7 ABSTRACT Most of the fires in Amazonia happen along an arc of deforestation, which generally follows the transition between the Amazon evergreen forests and the savannas (cerrado). The evergreen primary forest acts as a giant fire break, while the cerrado has adapted to frequent fires. The transitional zone between these two ecosystems is a fragile boundary controlled by very dynamic ecosystem processes. It is also an area with heavy pressures from human settlements that use fire as a way to clear and manage the land. Canopy disturbance of the primary forest due to increased selective logging and deforestation, along with extended droughts, alters the hydrological equilibrium of this ecosystem and therefore, the ecotone. High temperatures and very low relative humidity in disturbed stands increase the flammability of the primary forest. The deep rooting systems have an important role in supplying water during the dry season. As precipitation decreases, the primary forest is able to tap deep soil water; however, if the water supply is interrupted during an exceptionally dry year, the vegetation can dry and suffer leaf loss. Light penetration then increases, fuel moisture decreases, and fuels become dangerously flammable. This paper presents the main ideas of a fire susceptibility model that is being developed for the region. Key words: Fire, Forest Savanna Ecotone, Water Stress, Rooting Depth, GIS, Modeling, Tropics, Brazil. I - INTRODUCTION Fire and tropical rain forest are topics that seem unrelated; however today most of world’s vegetation fires occur in the tropical and subtropical regions (Goldammer and Manan 1996). -

Borassus Flabellifer Linn.) As One of the Bioethanol Sources to Overcome Energy Crisis Problem in Indonesia
2011 2nd International Conference on Environmental Engineering and Applications IPCBEE vol.17 (2011) © (2011) IACSIT Press, Singapore The Potential of Developing Siwalan Palm Sugar (Borassus flabellifer Linn.) as One of the Bioethanol Sources to Overcome Energy Crisis Problem in Indonesia Nisa Bila Sabrina Haisya 1, Bagus Dwi Utama 2, Riki Cahyo Edy 3, and Hevi Metalika Aprilia 4 1 Student at Faculty of Veterinary, Bogor Agricultural University 2 Student at Faculty of Agricultural Technology, Bogor Agricultural University 3 Student at Faculty of Economy and Management, Bogor Agricultural University 4 Student at Faculty of Forestry, Bogor Agricultural University Abstract. The energy demand in Indonesia increases due to a significant growth in population, this fact has diminished the fossil fuel storage as our main non renewable energy source. Recently, there are a lot of researches on renewable energy; one of the most prominent is the development of bioethanol as a result of fermentation of sugar or starch containing materials. Palm sugar as one of the natural sugar sources can be obtained from most of palm trees such as coconut, aren, nipah, and siwalan. This paper explored the potential of Siwalan palm sugar development to be converted into bioethanol as renewable energy source through fermentation and purification processes. Siwalan palm sugar contains 8.658 ml ethanol out of 100 ml palm sugar liquid processed using fermentation and distillation. Bioethanol can further utilized as fuel when it is mixed with gasoline that called gasohol. In the future, it is expected that gasohol can replace gasoline consumption as an alternative energy that can be competitive in term of price in Indonesia. -
Carpena, Pietro, TREE AID Supporting the Development Of
Carpena, Pietro, TREE AID Supporting the development of locally controlled small-scale enterprises based on non-timber forest products in Burkina Faso: TREE AID’s experience Authors: Pietro Carpena - TREE AID; Désiré Ouedraogo - TREE AID; Alexis Sompougdou - TREE AID; Barthélémy Kaboret - TREE AID In the fight against poverty the use of forest products are often quoted as having significant potential to improve the livelihoods of rural people living within or close to forest areas. TREE AID works in Africa’s drylands to unlock the potential of trees to tackle poverty and improve the environment. Non-timber forest products (NTFPs) are an important part of traditional livelihoods in the drylands of West Africa. Communities generally have free access to communal forest resources, and NTFPs are already an important alternative source of income for rural households – especially women. However, marketing forest products to reduce poverty can be hindered by several factors including poor management and business skills, lack of investment, poor market access and information and dwindling natural resource base. Over the last decade, through its programmes, TREE AID has guided the self-organisation of hundreds of village interest groups in Burkina Faso, Mali and Ghana to develop and manage small businesses, also known as village tree enterprise (VTE) groups, based on NTFPs. With support from the Market Analysis and Development (MA&D) approach developed by the Food and Agriculture Organization of the United Nations (FAO), TREE AID has provided the crucial structures that are necessary to achieve this empowerment. The support to VTEs groups covers all aspects of the NTFP value chain by facilitating market linkages and introducing private sector approaches to marketing and customer retention to ensure that expanded agricultural enterprise is achieved. -
