The distribution of different vegetation units and their relative health are critical for the
identification of land management issues, soil types, and indications as to the effectiveness of
management strategies. SPOT, LANDSAT and ASTER satellite imagery proved especially
effective in mapping the distribution of these associations, which also corresponded well with
vegetation structural units described in Specht (1981) and used to map units shown in
Appendix 2. Within the Mallee region, the valleys of the Murray River, Darling River and
Darling Anabranch are comparatively well vegetated with dense stands of trees and shrubs
(Brown and Stephenson 1991).
In the Lindsay-Wallpolla and Lake Victoria-Darling Anabranch region, the following
associations were observed on the equivalent geomorphic units. The regolith landform units
correlate well with vegetation densities, and with soil types (for soil type relationship see
Figure 7).
