The spatial dimensions, or components, of processes are actually surrogates for biodiversity processes that operate at a regional scale. Processes included the following (details are described in Cowling et al. 2003): SPATIALLY FIXED - Biome interfaces; Ecological diversification of plant lineages; 500m buffer of untransformed habitat along thicket and adjacent biome (fynbos, grassland, succulent karoo and Nama-karoo); STEP vegetation typesHabitat transformation - Sand movement corridors; Inland movement of marine sands and associated soil development; Functional corridor comprising intact source and sink areas; Sand massesHabitat transformation - Riverine corridors; Migration and exchange between inland and coastal biotas; 250m buffer of untransformed habitat along riverine systems linking coastal and inland subregions; Perennial riversHabitat transformation - Coastal interface; Migration and exchange between patches of coastal thicket; 500m buffer of untransformed habitat along the coast.; CoastlineHabitat transformation SPATIALLY FLEXIBLE - Upland-lowland gradients; Ecological diversification of plant and animal lineages; migration of biota; 1km-wide strip of untransformed habitat linking the upland STEP boundary and the coast within each bio-region; Bio-regionsHabitat transformation - Macroclimatic gradients; Geographic diversification of plant and animal lineages; migration of biota; 1km strip of untransformed habitat linking major biogeographic zones; STEP vegetation typesHabitat transformation Created for the Subtropical Thicket Ecosystem Planning Project, in order to identify spatial priorities for conservation action in the Thicket Biome.
