Deep peat occupies flat and gently sloping areas, but on steeper surfaces the mineral content of the soil increases and the peat mantle is generally less than 2 metres thick. The mass movement of peat, especially over impervious bedding planes in the sedimentary rocks, is widespread and conspicuous. Other forms of erosion include deep-seated slumps, and in isolated areas tunnel gully erosion and scree erosion. Wind erosion have occured, however, is the most extensive as revealed by blowout scars especially on exposed ridges and spurs at higher altitudes. Such scars appear to be healing on the northern side of the stock fence but are still being damaged by stock trampling in the south.
Damage associated with tracking is also very evident.
The soft, weakly consolidated peat is easily destroyed and this exposes the drier surface layer of soil to erosion by wind and water. Soil disturbance is also noticeable along the fence line. It was permanently manned from 1941 - 1995. Consequently stragglers and migrants are more likely to be recorded.
