This region is mainly semi-arid.
The northern coastline of this region is mainly rocky. Towards the south, the coastline undergoes a gradual change from steep and rocky to increasingly wider-spaced rocky headlands, separated by sweeping sand beaches.
Biological communities along the west coast generally exhibit low species richness, with high biomass values being achieved by a few species, including kelp, limpets, black mussels, abelone, rock lobsters and a number of fish and bird species.
