5.2 Washes
The drainage lines within the plains of the study area are regarded as washes, as
water will only flow after good rains, and soon they will be dry again. These washes
are wide and sandy, and blend into the landscape, merging with the adjacent
grassland vegetation. They are however noticeable on good quality areal photos.
The vegetation is often somewhat heterogeneous and with weeds, due to the
disturbance of the periodic flooding. The species composition is similar to that of the
pans, given above.
Washes are of conservation concern and regarded as sensitive ecosystems, due to
the ecosystem processes linked to provision and transport of water in the landscape.
