Herpetofaunal Survey of the Ongeluksnek (Malekgalonyane) Nature Reserve in the Foothills of the Drakensberg, Eastern Cape Province, South Africa
Herpetology Notes, volume 13: 717-730 (2020) (published online on 25 August 2020) Herpetofaunal survey of the Ongeluksnek (Malekgalonyane) Nature Reserve in the foothills of the Drakensberg, Eastern Cape Province, South Africa Werner Conradie1,2,* Brian Reeves3, Sandile Mdoko3, Lwandiso Pamla3, and Oyama Gxabhu3 Abstract. 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.

Tulbagh Renosterveld Project Report
BP TULBAGH RENOSTERVELD PROJECT Introduction The Cape Floristic Region (CFR) is the smallest and richest floral kingdom of the world. In an area of approximately 90 000km² there are over 9 000 plant species found (Goldblatt & Manning 2000). The CFR is recognized as one of the 33 global biodiversity hotspots (Myers, 1990) and has recently received World Heritage Status. In 2002 the Cape Action Plan for the Environment (CAPE) programme identified the lowlands of the CFR as 100% irreplaceable, meaning that to achieve conservation targets all lowland fragments would have to be conserved and no further loss of habitat should be allowed. Renosterveld , an asteraceous shrubland that predominantly occurs in the lowland areas of the CFR, is the most threatened vegetation type in South Africa . Only five percent of this highly fragmented vegetation type still remains (Von Hase et al 2003). Most of these Renosterveld fragments occur on privately owned land making it the least represented vegetation type in the South African Protected Areas network. More importantly, because of the fragmented nature of Renosterveld it has a high proportion of plants that are threatened with extinction. The Custodians of Rare and Endangered Wildflowers (CREW) project, which works with civil society groups in the CFR to update information on threatened plants, has identified the Tulbagh valley as a high priority for conservation action. This is due to the relatively large amount of Renosterveld that remains in the valley and the high amount of plant endemism. The CAPE program has also identified areas in need of fine scale plans and the Tulbagh area falls within one of these: The Upper Breede River planning domain. -

Epigaeic Invertebrate Community Structure in Two Subtropical Nature Reserves, Eastern Cape, South Africa: Implications for Conservation Management
© Arachnologische Gesellschaft e.V. Frankfurt/Main; http://arages.de/ Arachnologische Mitteilungen / Arachnology Letters 52: 7-15 Karlsruhe, September 2016 Epigaeic invertebrate community structure in two subtropical nature reserves, Eastern Cape, South Africa: Implications for conservation management Augustine S. Niba & Inam Yekwayo doi: 10.5431/aramit5203 Abstract. Epigaeic invertebrates were sampled at non-invaded (‘Indigenous Forest’ and ‘Indigenous Grassland’) and alien-invaded (‘Eu- calyptus’ and ‘Mixed alien’) sub-sites in the Nduli and Luchaba Nature Reserves using pitfall traps. A total of 2054 specimens belonging to three phyla (Arthropoda, Mollusca and Annelida) was caught and sorted into seven orders, 18 families, one tribe, 45 genera (22 identified to species level) and 20 morphospecies. Higher species richness occurred in ‘Indigenous Forest’ and ‘Mixed Alien’ sub-sites while higher specimen counts were made in invaded (‘Mixed Alien’ and ‘Eucalyptus’) sub-sites during summer months, peaking in January. Canonical Correspondence Analysis results show that some measured site variables, e.g. litter depth, grazing intensity, percentage of alien vege- tation cover, and soil chemical properties accounted for invertebrate taxa composition and distribution trends at sub-sites. Although habitat-patch level characteristics (including abiotic factors) were important for determining species distributions, increased levels of infestation by invasive alien vegetation across sub-sites did not necessarily impact on epigaeic invertebrates -

The project is an update and extension of the first Southern African Bird Atlas Project (SABAP1) which ran from 1987–1991, and included six countries of southern Africa, including Namibia. It culminated in the publication of the Atlas of Southern African Birds in 1997. The bird atlas project in Namibia is partnership between the Namibian Ministry of Environment and Tourism, the Namibia Bird Club and the Animal Demography Unit, University of Cape Town (ADU). The project plans to run indefinitely. The broad aim of the project is to determine the distribution and abundance of bird species in Namibia, and to investigate how environmental change and development have impacted bird distributions over the past quarter of a century. It also aims to promote public awareness of birds through large-scale mobilization of ‘citizen scientists’. The project entails volunteer bird- watchers recording bird species in five-minute grid cells (approx. 8 km × 9 km) called pentads. This information is then sent to the Animal Demography Unit at the University of Cape Town where the data is captured into a central database. It is important for observers to try and cover as much of the grid cells as possible in order for an accurate and comprehensive bird list to be compiled for the area. -
Fruit Nutritional Composition and Non-Nutritive Traits of Indigenous South African Tree Species ⁎ A.-L
Available online at www.sciencedirect.com South African Journal of Botany 78 (2012) 30–36 www.elsevier.com/locate/sajb Fruit nutritional composition and non-nutritive traits of indigenous South African tree species ⁎ A.-L. Wilson, C.T. Downs School of Biological and Conservation Sciences, University of KwaZulu-Natal, Private Bag X01, Pietermaritzburg 3209, South Africa Received 12 January 2011; received in revised form 11 April 2011; accepted 13 April 2011 Abstract Frugivorous animals play a major role in dispersing tropical, and to a lesser extent, temperate tree species. In order to attract potential seed dispersers, plants generally offer a reward of fleshy fruit pulp. Criteria for fruit choice by avian frugivores are influenced by a number of non- nutritive (e.g. fruit size and colour) factors; and nutritional composition of the fruit. There is a paucity of nutritional composition and other fruit trait data of indigenous South African fruit. This information is necessary in order to determine which frugivores are likely to ingest which fruits and consequently act as potential seed dispersal agents. This information would provide us with an understanding of the inter-relationships between indigenous fruit and frugivores in South Africa. Consequently nutritional composition was investigated in various indigenous fruit species that avian frugivores feed on. Fruits were collected from 38 indigenous tree species found in KwaZulu-Natal Afromontane and coastal forests. Pulp was freeze-dried to constant mass and then analysed for sugar, lipid and protein content; and for water content determination. Fruit width in this study ranged from 4 mm (Searsia rehmanniana and Trema orientalis)to40mm(Annona senegalensis, Ficus sur and Xylotheca kraussiana). -
Fire Management
FACT SHEET The Landowner’s Guide to FIRE MANAGEMENT eriodic natural fires have always occurred in fynbos and probably in renosterveld systems too. Many plants actually need fires to reproduce and ensure their long-term survival. The Pchallenge now is to use fire in a fragmented and highly modified modern landscape to ensure the survival of all plant and animal species that live in the landscape. Although fynbos is a fire-adapted system, just one or two inappropriate fires at the wrong time of year or wrong frequency, can cause the local extinction of many species. The most important use of fire for conservation management is to maintain viable populations of all existing plant and animal species. The use of fire to achieve other management objectives should always take this into account. These may include: reduction in fuel load to prevent unmanageable wildfires, the control of invasive alien plants, increase in water yield from catchments, promoting desirable plants for the flower picking industry, or improving grazing. Principles of Fire Management Frequency can contain a high proportion of grasses, which are fast- growing and highly flammable, renosterveld can be The interval between fires should largely be deter- burned more frequently than fynbos, possibly every mined by the growth rate of existing plants.

We explored all of these and more during our 25-day adventure across the country. Highlights were many and included Orange River Francolin, thousands of Cape Gannets, multiple Secretarybirds, stunning Knysna Turaco, Ground Woodpecker, Botha’s Lark, Bush Blackcap, Cape Parrot, Aardvark, Aardwolf, Caracal, Oribi and Giant Bullfrog, along with spectacular scenery, great food and excellent accommodation throughout. ___________________________________________________________________________________ Despite havoc-wreaking weather that delayed flights on the other side of the world, everyone managed to arrive (just!) in South Africa for the start of our keenly-awaited tour. We began our 25-day cross-country exploration with a drive along Zaagkuildrift Road. This unassuming stretch of dirt road is well-known in local birding circles and can offer up a wide range of species thanks to its variety of habitats – which include open grassland, acacia woodland, wetlands and a seasonal floodplain.
