A landscape approach used in designing a representative reserve system for the Eastern Cape Province of South Africa
… in order to propose a representative system of reserves which would protect the biodiversity within the study area. A technique based on the "Gap Analysis Programme" was used. This involved the determination of the representativeness of natural landscapes within the existing reserves, the …

Adapting Protected Area Networks to the Impacts of Climate Change: Potential Options for the Sub-Saharan Africa Important Bird Area (IBA) Network
… 2071-2100 were used. Initially, using a reserve selection algorithm (RSA), I created optimal PA networks of one- and quarter-degree cells for present and future time periods. I then created near-optimal reserve networks using IBAs alone, or permitting the selection of additional …

Strategic revegetation planning in an agricultural landscape: A spatial information technology approach
… area and a complex effect of land clearance and reserve selection on representativeness is revealed which has significant implications for strategic revegetation planning. Land clearance has precluded the use of information on the spatial distribution of biological diversity in agricultural …

The preservation of the Cape flora : status, causes of rarity, ideals and priorities
… Although 19 per cent of the CFR occurs in nature reserves, by far the majority of the preserved area comprises Mountain Fynbos. Only 0.5 and 3 per cent of the original extent of Renoster Shrub/and Lowland Fynbos is preserved, respectively. In this study Fynbos vegetation is identified as the …

Flora of the Cape Peninsula : endemism, threatened plants and conservation in perspective
… Information System (GIS) showed the present reserve system inadequate in terms of protecting all plant and endemic faunal species on the Peninsula. The inclusion of all publicly owned land into the reserve system improved the conservation status dramatically, with only 13 species remaining …

Distributional Modeling Of Rare Fishes And Mussels: From Ecological Theory To Biodiversity Conservation
… I developed a hierarchical approach to the selection and management of freshwater protected areas in the upper Green River system. By aligning the spatial scales and environmental variables analyzed at each stage in the conservation planning process, from species distribution modeling to …

Systematic conservation planning and South Africa's Forest Biome: An assesment of the conservation status of South Africa's forest and reccomdentations for their conservation
… Berliner The limitations of the mathematical selection algorithms (C-plan and MARXAN) to incorporate ecological heuristics and context specific information within reserve selection were recognised. In response to this, a rule based modelling approach was used, that enables ecological …

Conservation of polychaete biodiversity within the Port Stephens-Great Lakes Marine Park
… its temporal dynamics, is problematic for the selection and design of MPAs. To overcome this constraint, habitats are commonly used as a biodiversity surrogate for biodiversity in marine conservation planning to select MPAs and draw zone boundaries. This research tested the validity of two …

Identifying, understanding, and conserving rare species
En cette époque de déclin de la biodiversité à l’échelle mondiale, les espèces rares méritent une attention particulière dans les efforts de conservation, car elles sont plus vulnérables à l'extinc-tion que les espèces communes. À la suite de l'adoption du Cadre mondial pour la biodiversité …
