October 2017 Monthly Report October 2017 Monthly Report “Look deep into nature, and then you will understand everything better.” –Albert Einstein. A quieter month for the Conservancy, October provided us with an opportunity to reflect on our programmes and activities. Together with the day-to-day operations, data collected on fishing in the area was analysed and a management meeting was held. The overarching goal of the conservancy is to preserve the natural heritage of the area for present and future generations. Stepping back and assessing in what ways we are succeeding, and where we still need to improve, is vitally important. It is equally important to do this in one’s own life and ensure that what we are doing today is getting us closer to where we want to be tomorrow. We hope you enjoy the read! Vegkop greets us with a beautiful view of dune, vegetation and ocean. Compliance During October, a total of 48 recreational fishing, spearfishing and bait collecting permits were checked by Kei and Anton. Of the 48 permits checked, 11 people (23%) failed to produce a valid permit and were issued a verbal warning. As we mentioned last month, the season for Galjoen, Dichistius capensis, has closed on the 15th of October and will reopen on the 1st of March 2018. 2 October 2017 The season for Shad (Elf), Pomatomus saltatrix, also closed on the 1st of October and will reopen on 1st December. Let us all leave these fish so that they can breed in peace. Roving Creel Survey Results Roving Creel is a research survey currently in its 8th year at the Conservancy. It is one of numerous studies implemented by Professor Colin Attwood across the South African coastline. This study was originally initiated in the area by Wayne Meyer, a former senior Ranger, in 2009. It primarily determines the Catch per Unit Effort (CPUE) of each recreationally targeted fish species. In simple terms, this means the amount of effort it takes to catch a fish. If many fish of a species are readily caught, it is thought that the population is healthy in that area, versus a species where one undersized fish is caught in a year. This information can be used to assess fish stock and whether fishing regulations in place for each species are effective, as well as judging the need for Marine Protected Areas. Each year, one of the students tackles (excuse the pun) the task of conducting these surveys. This entails walking along the coast at randomised times and conducting interviews with fishermen encountered. This year, Nicole has been doing the surveys and has built up a substantial information base. The results were analysed and provided some interesting outcomes which will be summarised here. From January to October, 80 surveys were done which yielded 388 interviews. Many of these interviews were with small groups of fishermen, meaning a total of 818 anglers were interviewed. Of these, 619 were locals and the rest are visitors. Three surveys recorded no fishermen. These interviews are not for the purposes of compliance, as it is thought that more accurate interviews will be achieved. Anton and Kei conducted the compliance patrols and these results will be compiled at the end of the year. As such, Roving Creel is very non-confrontational and no survey has been refused yet. 734 Anglers fished on weekends and public holidays while only 86 fished in the weekdays. Popular fishing seasons included autumn and spring, of which the months of April and September had the most anglers. This is likely due to the school holidays and numerous public holidays during these times. Occurance of fishermen over weekends and weekdays in 140 2017 120 Weekend 100 80 Weekday 60 40 Linear (Weekend) Fishermen Fishermen (number) 20 0 17 11 0 12 6 3 12 6 7 12 January February March April May June July AugustSeptemberOctober Month of Year 3 October 2017 93 Fish were caught, consisting of 19 different species. 24% of the fish caught were released again, which was largely due to the catch-and-release fishing competitions held in the area. Some non- competitive fishermen also believe in releasing their catch on a regular basis. The largest fish caught were non-edibles (sharks and rays usually targeted by game fisherman) while the smallest fish included edibles (fish you would usually eat), which could suggest that the edibles are targeted more and are thus under more pressure in this area. We thought it would be interesting to compare the 2017 data to the 2009 data, from when the surveys first began. In 2009 only 283 anglers were interviewed (compared to 818 in 2017). The same number of surveys were conducted, thus this increase in interviews shows the massive increase in coastal users and pressure put on coastal systems. In 2009, 68 fish were caught, representing 12 different species. Thus, the ratio of fish to anglers was much larger then. In 2017, it was roughly 1 fish per 8 anglers, whereas in 2009 it was roughly 1 fish per 4 anglers. Another disparity is that only 3% of catches were released in 2009, so either fewer catch-and-release competitions were held then, or competitions also kept their catches and fewer fishermen had the mentality to release their fish. More fishermen fished during winter in the 2009 survey, but the weekend to weekday fishing ratio is much the same as in 2017. Looking at these data, it is clear that the CPUE of fish species has definitely decreased from 2009 to 2017. In other words, it takes more effort to catch a fish now than it did in 2009. Thus, despite regulations and marine protected areas in place, we still have a long road ahead to ensure the security of South Africa’s fish resources. The Roving Creel data will be more accurately analysed after another two years of conducting the surveys (i.e. to total ten years of data). This is just a start to the more in-depth analysis that will take place then, and this article does not negate all possible bias and confounding factors. Fransmanshoek en Omgewing Book Alletta Hanekom wrote the Fransmanshoek en Omgewing book to commemorate the area, its timeless beauty and its classic people. Fransmanshoek is a place with a rich history and this book delves into topics that have intrigued many, with chapters like “Vanwaar die naam, Hengelsplesier, Omgewingstuin, Fransmanshoek Bewarea” and many more. The newest edition of this book as now been published, with updated stories and never-before published chapters. It will also be available in English in the near future. The book is for sale for R150 and can be purchased from the Fransmanshoek Conservancy offices or the Vleesbaai Shop. Funding obtained will be put back into the running costs of the Conservancy. Beach Clean Ups During the month of October, during the Durban storms, a massive wind hit the Conservancy. This caused havoc, with hundreds of objects washing ashore. The beaches were littered with items ranging from unused Nike shoes, homemade brooms, “Teachers whiskey” and old rusted barrels. The Rangers made quick work of this phenomenon and collected more than five bags of trash during their patrols. The barrels remain, but these will be removed as soon as possible. 4 October 2017 One of the many glass bottles washed ashore. Nurdles, which are small plastic balls used to make plastic products, have polluted our oceans recently. Marine animals mistake these balls for food and ingest them. The animals struggle to digest them and they can cause blockages in the intestines. They are also believed to release toxins into the animal’s body and cause death if in high enough concentrations. The nurdles are small, making removing them a mammoth task. Look out for the November report for an update on this! Reptile Encounters ~Snake Sightings The days are growing warmer and snake activity is consequently increasing. The Rangers were blessed to witness four distinct species this month in their natural habitats. At the Fransmanshoek Peninsula they saw a puffadder, Bitis arietans and spotted skaapsteker, Psammophylax rhombeatus. A boomslang, Dispholidus typus, was found in a bird’s nest. Lastly, a dead spotted harlequin snake, Homoroselaps lacteus, was seen at Kanon. The spoor in the photo below is indicative of a thick puffadder that crossed the road. Puffadder marks are easy to identify because they usually travel in a straight line, except when disturbed. A cobra’s spoor is more like the typical snake spoor imagined where it goes from side to side in a curved manner. It should be noted that three of these snakes were found in roads. Please be careful when driving around when it’s hot outside and keep a lookout for any tortoises or snakes crossing the road. 5 October 2017 From top left, clockwise: Spotted Harlequin snake; Puffadder; Spotted Skaapsteker and the spoor of a Puffadder. ~Snake Capture and Release On the 31st, the Conservancy received a callout to remove a snake from a Boggomsbaai resident’s garage. The Boomslang was identified and appeared to be after a sparrow’s nest. Anton rushed to the scene and with the help of Boggomsbaai’s own snake handler, Patrys Spykerman, the two worked together to remove the snake and put it in the snake box. The snake was then relocated to the veld far away from humans.

Matters discussed included the seasonal activities which would include guided walks by appointment through Snuifklip and the Geoff Cowley path, the annual environmental education “Intertidal Day” aimed at children in the area, another movie in the dunes evening, a flora and fauna walk for Springerbaai residents in their own backyard and several beach clean ups by the visitors, for the visitors.

The results of a herpetofaunal survey of Ongeluksnek Nature Reserve, Eastern Cape Province, South Africa are presented here. Combination of visual encounter survey methods and standard Y-shape trap arrays were used to conduct the survey. A total of 26 species (eight amphibians and 18 reptiles) were recorded, representing 29 quarter-degree grid cell records, of which 62% represented the first records for these units. Furthermore, we document the presence of three species of snakes (Crotaphopeltis hotamboeia, Hemachatus haemachatus and Homoroselaps lacteus) for the first time for the whole degree square of 3028 (approx. 100 km2). This study highlights the need to survey poorly known regions to enable us to understand and document the full distributional extent of species. We also discuss the impact of uncontrolled fires on the absence of grassland specialised species during our survey. Keywords.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

  • Ancestral Reconstruction of Diet and Fang Condition in the Lamprophiidae: Implications for the Evolution of Venom Systems in Snakes

KGADITSE, AND GRAHAM J. ALEXANDER 1School of Animal, Plant and Environmental Sciences, University of the Witwatersrand, Johannesburg. PO Wits, 2050, Gauteng, South Africa ABSTRACT.—The Colubroidea includes all venomous and some nonvenomous snakes, many of which have extraordinary dental morphology and functional capabilities. It has been proposed that the ancestral condition of the Colubroidea is venomous with tubular fangs. The venom system includes the production of venomous secretions by labial glands in the mouth and usually includes fangs for effective delivery of venom. Despite significant research on the evolution of the venom system in snakes, limited research exists on the driving forces for different fang and dental morphology at a broader phylogenetic scale. We assessed the patterns of fang and dental condition in the Lamprophiidae, a speciose family of advanced snakes within the Colubroidea, and we related fang and dental condition to diet. The Lamprophiidae is the only snake family that includes front-fanged, rear-fanged, and fangless species. We produced an ancestral reconstruction for the family and investigated the pattern of diet and fangs within the clade. We concluded that the ancestral lamprophiid was most likely rear-fanged and that the shift in dental morphology was associated with changes in diet. This pattern indicates that fang loss, and probably venom loss, has occurred multiple times within the Lamprophiidae.

  • Early German Herpetological Observations and Explorations in Southern Africa, with Special Reference to the Zoological Museum of Berlin
    Bonner zoologische Beiträge Band 52 (2003) Heft 3/4 Seiten 193–214 Bonn, November 2004 Early German Herpetological Observations and Explorations in Southern Africa, With Special Reference to the Zoological Museum of Berlin Aaron M. BAUER Department of Biology, Villanova University, Villanova, Pennsylvania, USA Abstract. The earliest herpetological records made by Germans in southern Africa were casual observations of common species around Cape Town made by employees of the Dutch East India Company (VOC) during the mid- to late Seven- teenth Century. Most of these records were merely brief descriptions or lists of common names, but detailed illustrations of many reptiles were executed by two German illustrators in the employ of the VOC, Heinrich CLAUDIUS and Johannes SCHUMACHER. CLAUDIUS, who accompanied Simon VAN DER STEL to Namaqualand in 1685, left an especially impor- tant body of herpetological illustrations which are here listed and identified to species. One of the last Germans to work for the Dutch in South Africa was Martin Hinrich Carl LICHTENSTEIN who served as a physician and tutor to the last Dutch governor of the Cape from 1802 to 1806. Although he did not collect any herpetological specimens himself, LICHTENSTEIN, who became the director of the Zoological Museum in Berlin in 1813, influenced many subsequent workers to undertake employment and/or expeditions in southern Africa. Among the early collectors were Karl BERGIUS and Ludwig KREBS. Both collected material that is still extant in the Berlin collection today, including a small number of reptile types. Because of LICHTENSTEIN’S emphasis on specimens as items for sale to other museums rather than as subjects for study, many species first collected by KREBS were only described much later on the basis of material ob- tained by other, mostly British, collectors.

  • A Plant Ecological Study and Management Plan for Mogale's Gate Biodiversity Centre, Gauteng
    A PLANT ECOLOGICAL STUDY AND MANAGEMENT PLAN FOR MOGALE’S GATE BIODIVERSITY CENTRE, GAUTENG By Alistair Sean Tuckett submitted in accordance with the requirements for the degree of MASTER OF SCIENCE in the subject ENVIRONMENTAL MANAGEMENT at the UNIVERSITY OF SOUTH AFRICA SUPERVISOR: PROF. L.R. BROWN DECEMBER 2013 “Like winds and sunsets, wild things were taken for granted until progress began to do away with them. Now we face the question whether a still higher 'standard of living' is worth its cost in things natural, wild and free. For us of the minority, the opportunity to see geese is more important that television.” Aldo Leopold 2 Abstract The Mogale’s Gate Biodiversity Centre is a 3 060 ha reserve located within the Gauteng province. The area comprises grassland with woodland patches in valleys and lower-lying areas. To develop a scientifically based management plan a detailed vegetation study was undertaken to identify and describe the different ecosystems present. From a TWINSPAN classification twelve plant communities, which can be grouped into nine major communities, were identified. A classification and description of the plant communities, as well as, a management plan are presented. The area comprises 80% grassland and 20% woodland with 109 different plant families. The centre has a grazing capacity of 5.7 ha/LSU with a moderate to good veld condition. From the results of this study it is clear that the area makes a significant contribution towards carbon storage with a total of 0.520 tC/ha/yr stored in all the plant communities.
