摘要

Large-scale afforestation with pines (Pinus sp.) is taking place in montane grasslands of South Africa. Many species dependent on the grass sward will be eliminated from the planted areas, and it is suggested that land should be maintained as conservation areas to ensure the long-term survival of the wildlife within the afforestable region. A total of 10 land types, defined by combinations of classes of geology, altitude and rainfall, were sampled during 1993-96 in the afforestable part of the Maclear district, Eastern Cape Province. 41 genera of grasshoppers, 45 species of butterflies, 980 species of birds, and 10 species of small mammals were recorded in the survey. It was found that conservation areas of 5 land types, in a network, would be required to protect all the montane-endemic grasshopper, butterfly and bird species recorded (10, 12, and 12 species, respectively). It was considered that the addition of a sixth land type would protect 93.8% of all the taxa recorded. Regions within whichconservation areas should be situated are indicated at the district scale.
