Last word……………………………13 The Convention on Biological Diversity (CBD) was inspired by the world community's growing commitment to sustainable development. It represents a dramatic step forward in the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising from the use of genetic resources. The IUCN Red Listing activity is the world’s most comprehensive information source on the global conservation status of wild species and their links to livelihoods. Far more than a list of species and their status, it is a powerful tool to inform and catalyse action for biodiversity conservation, critical to protecting the natural resources we Editors and coordinators: need to survive. Ansie Dippenaar-Schoeman & Robin Lyle Preparation for Red Data assessments ARC-Plant Protection Research Institute Private Bag X134 As part of SANSA, species data was gathered throughout the years to help with the Red Data Queenswood, 0121 assessments. In preparation for determining the conservation status of each species, a rarity index South Africa (RI) was developed based on an endemicity index (EI) and abundance index (AI). The EI (i.e. dis- tribution of a species) included seven categories, ranging from: E-mail: [email protected] & [email protected] 6 = endemic-known only from type locality / one locality only Charles Haddad 5 = known from one province only, wider than type locality Department of Zoology & Entomology University of the Free State 4 = known from two adjoining provinces only P.O. Box 339 Bloemfontein, 9300 3 = South Africa >two provinces or not adjoining South Africa 2 = Southern Africa (south of Zambezi and Kunene Rivers) E-mail: [email protected] 1 = Afrotropical Region 0 = Cosmopolitan This data was compiled based on currently known distribution data available from the literature, SA SPIDER Spider World Catalogue, and information from the SANSA database and Virtual Museum. The abundance index was an estimate of population size based on the number of collecting records COUNT known for each species in the SANSA database. It was divided into three categories: 1 – abun- dant, known from >10 localities; 2 – rare, known from between 4–10 localities; and 3 – very rare, only known from 3 or < localities. JANUARY 2015 2171 spider spp. Team members of SANSA under leadership of the ARC team, along with the Threatened Species JUNE 2015 Programme (TSP) (Dr Theresa Sethusa and Mrs Domitilla Raimondo) of the South African Nation- al Biodiversity Institute (SANBI), have spent the past two years evaluating the South African spider 2192 spider spp. species against the ICUN Categories and Criteria. All of the 2171 species will be evaluated, and this information will be made available through an updated Atlas and Red List. The information will also feed into the species pages being generated by SANBI for the Encyclopaedia of Life.
