Abstract
The South Coast Renosterveld has been fragmented extensively by agriculture. The extent of this fragmentation in terms of overall habitat loss, fragment sizes and fragment numbers has not been described previously, thereby limiting the development of conservation strategies for this vegetation type. Patterns of renosterveld loss in three sectors along a west–east gradient were described using LANDSAT imagery and a Geographical Information System‐based program (FRAGSTATS) for spatial pattern analysis. These patterns were then correlated with rainfall and topography measures, which are indicators of agricultural potential. Over 80% of the South Coast Renosterveld has been cultivated. Fragmentation levels increased significantly from east to west, with 33% of natural vegetation remaining in the east and only 4% in the west. Topographical variables were the strongest predictors of patterns of renosterveld loss, with fragments being largely confined to slopes too steep for ploughing; they therefore face little risk of future cultivation. These results have implications for conservation planning options for the South Coast Renosterveld. There is the potential for large reserves in the east, as well as corridor reserves along major river valleys, but for only small, isolated reserves in the west.

The extent of this fragmentation in terms of overall habitat loss, fragment sizes and fragment numbers has not been described previously, thereby limiting the development of conservation strategies for this vegetation type. Patterns of renosterveld loss in three sectors along a west–east gradient were described using LANDSAT imagery and a Geographical Information System‐based program (FRAGSTATS) for spatial pattern analysis. These patterns were then correlated with rainfall and topography measures, which are indicators of agricultural potential. Over 80% of the South Coast Renosterveld has been cultivated. Fragmentation levels increased significantly from east to west, with 33% of natural vegetation remaining in the east and only 4% in the west. Topographical variables were the strongest predictors of patterns of renosterveld loss, with fragments being largely confined to slopes too steep for ploughing; they therefore face little risk of future cultivation. These results have implications for conservation planning options for the South Coast Renosterveld. There is the potential for large reserves in the east, as well as corridor reserves along major river valleys, but for only small, isolated reserves in the west.</abstract><subject lang="en"><genre>keywords</genre><topic>agriculture</topic><topic>conservation planning</topic><topic>environmental predictors</topic><topic>habitat loss</topic><topic>landscape fragmentation</topic><topic>renosterveld</topic></subject><relatedItem type="host"><titleInfo><title>Austral Ecology</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">1442-9985</identifier><identifier type="eISSN">1442-9993</identifier><identifier type="DOI">10.1111/(ISSN)1442-9993</identifier><identifier type="PublisherID">AEC</identifier><part><date>2000</date><detail type="volume"><caption>vol.</caption><number>25</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>179</start><end>186</end><total>8</total></extent></part></relatedItem><identifier type="istex">D61781658BE69702ED64828BE42016C64E93E483</identifier><identifier type="DOI">10.1046/j.1442-9993.2000.01012.x</identifier><identifier type="ArticleID">AEC1012</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Science Pty</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
