Grassland, rich in wild flowers, occupies more than half the area, especially on the north-facing slopes. Sparse woodland – acacias in valley bottoms, proteas higher up – grows on warmer, drier sites. Tall, evergreen, Afro-montane forest is typical on cooler slopes, and in kloofs protected from fire. Marginally damp areas, especially near rocks and streams, support scrub and thicket. High ground is dominated by rocks, including a near-complete amphitheatre of cave sandstone. Wetlands are represented by permanently flowing streams with rapids and waterfalls.
