The attitudes and behaviours of private landholders toward the conservation of a highly transformed and critically endangered
habitat, Overberg Coastal Renosterveld (OCR) (a grassy shrubland of the Cape Floral Region, South Africa) are described. Personal,
semistructured interviews were conducted with landholders, representing 40 properties in the Overberg region, on topics such
as management and utilisation of OCR, the depth of their knowledge of its conservation importance, what they perceive its
value to be, and the extent of their willingness to conserve it. General attitudes toward conservation incentives and provincial
conservation authorities were also investigated. Farmers more willing to conserve were younger, did not necessarily have a
better education, and owned larger farms (>500 ha) with a greater amount of remnant renosterveld (>300 ha) than those less
willing to conserve. Attitudes toward the OCR were largely negative, related to associated problem plants and animals and
the fact that it is believed not to be economically advantageous to retain it. However, farmers are of the opinion that provision
of incentives and increased extension support will provide practical positive inducements for conservation. Landholder education
is paramount to prevent further transformation of critically endangered habitats. The success of private-conservation programs
depends on the attitudes of landowners toward (1) the particular habitat or species to be conserved (which can vary depending
on the type of land use practised and the associated benefits and disadvantages of that habitat type); (2) the conservation
agency or extension officers responsible for that area; and (3) willingness of landowners to participate in a conservation
program, which is influenced by landowner age, farm size, and the amount of natural habitat left to conserve. 相似文献

Spatial and temporal variations in vegetation are examined in relation to land tenure, population increase, and rainfall variation in a part of Peddie district, Eastern Cape. Sequential aerial photographs between 1938 and 1988 are analyzed to determine trends in vegetation and population change in three different land-tenure units. The areal extent at each date of four distinct vegetation categories is determined using PC ARC/INFO GIS. Long-term annual rainfall trends for the area are analyzed and juxtaposed with vegetation changes. Extensive ground-truthing exercises are carried out to verify the present condition of vegetation condition in terms of cover and species composition. Differences in land-tenure systems are discerned as the dominant factor controlling variations in vegetation degradation. The study also reveals that neither population changes nor rainfall variations can explain the observed trends in vegetation degradation. Earlier injudicious land-use practices, sustained since the turn of the last century, may provide plausible explanations for the trends and present status of vegetation degradation in the area. 相似文献
