Site description Located 20 km south of Matjiesfontein and 20 km south-west of Laingsburg, the Anysberg Nature Reserve is situated on the poorly known western fringe of the Little Karoo in a broad fynbos–Karoo transition zone. The reserve is one of the largest in the Western Cape and it lies in part of the Anysberg Mountain Catchment Area, which drains into the Gourits river system. The topography is mainly mountainous, interspersed with wide open valleys. The southern and northern boundaries of the reserve are formed by the Anysberg (1,622 m) and Suurkloofse Berg (1,512 m) ranges respectively. A third, drier mountain range, Matjiesgoedberg, dominates the central sector of the reserve.

Two major vegetation-types are present: Karoo scrub and bush on the plains and lower slopes, and montane fynbos at higher elevations. The great altitudinal variation yields a wide diversity of microhabitats. The scrub vegetation of the plains and lower escarpment consists chiefly of shrubs smaller than 70 cm in height. Members of the Mesembryanthemaceae, which can be very local in their distribution, dominate the vegetation. Belts of Acacia-dominated vegetation line the mostly dry riverbeds. Low stony ridges hold transitional vegetation, with Rhigozum dominating. As the vegetation stretches up the mountains, fynbos elements appear, and there are extensive stands of Protea woodland in the wetter areas.
