Landscape values in the Orroral Valley are enhanced by the contrast between the naturally wooded rugged heights which encompass the valley and the anthropogenic [of human origin] grasslands of the valley. Ridges that enclose the valley provide a sense of seclusion which is reinforced by the solitary homestead complex (1860s). The presence at the Orroral Valley Satellite Tracking Facility of a cultivated setting that incorporates exotic plants offers an interesting statement of landscape values which prevailed at the time the station was constructed Exotic species contrast with the natural vegetation and provide a micro-urban setting within the rural and natural scene (Egloff 1988:22).
