The shapefile is mainly based on the map of White (F. Bourliere (1983). Ecosystems of the world. No.13. Tropical

 

compilation:

savannas. Elsevier Scientific Publishing Company, Amsterdam. 730 pp). However, the terminology and map boundaries

 

 

of some units in the southern and northern parts have been slightly adapted according to the biome map of southern

 

 

Africa by Rutherford & Westfall (1994) (M.C. Rutherford & R.H. Westfall (1994). Biomes of Southern Africa: An

Notes on data, analysis and

The compilation of this map by Antje Burke, Wynand du Plessis & Ben Strohbach was based on existing information

 

compilation:

available from:

 

 

 

 

 

1) Giess’ preliminary vegetation map (1971)

 

 

2) published vegetation maps for parts of the country (Leser 1972; Viljoen 1980; Williamson 1997)

 

 

3) vegetation maps recently completed as part of regional environmental profiles (Hines in Mendelsohn & Roberts

 

 

1997; Mendelsohn et al. 2000; Burke 2000)

 

 

4) vegetation mapping project at the National Botanical Research Institute (Strohbach in press)

 

 

5) vegetation survey information at the Etosha Ecological Institute (le Roux et al. 1988; Sannier et al. 1995, 1998; du

 

 

Plessis 1999, 2000)

 

 

6) the Agro-ecological zones project at the Ministry of Agriculture, Water and Rural Development (de Pauw & Coetzee

 

 

1999).

 

 

 

 

 

This new vegetation map is consequently a product of review and synthesis. The background information available for

 

 

this review differed significantly in terms of (a) date, (b) coverage, (c) scale and accuracy of mapping, (d) format (e)

 

 

quality and quantity of accompanying data. Although this map provides more detail than the preliminary vegetation

 

 

map of 1971, policy makers, conservation and resource planners, and whoever wishes to use the map for further

 

 

analysis are cautioned to take these short-comings into account.

 

 

 

 

 

The broad Vegetation Types present ecologically similar map units, largely controlled by climate, topography and

 

 

underlying substrate. For example, the dwarf succulent shrubland of the southern Namib encompasses a diverse mosaic of

 

 

dwarf shrubland and shrubland communities with different plant species dominant in different parts of this area.
