Table 11 Ground Surface Visibility (GSV) Rating<br />
Description<br />
Heavy vegetation with scrub foliage, debris cover and/or dense tree cover.<br />
Ground surface not clearly visible.<br />
Moderate level of vegetation, scrub or tree cover. Small patches of soil surface<br />
visible resulting from animal tracks, erosion or blowouts. Patches of ground<br />
surface visible.<br />
Moderate levels of vegetation, scrub and/or tree cover. Moderate sized patches<br />
of soil surface visible possibly associated with animal tracks, walking tracks and<br />
erosion surfaces. Moderate to small patches across a larger section of the<br />
project area.<br />
Moderate to low level of vegetation, tree and/or scrub. Greater amounts of<br />
areas of ground surface visible in the form of erosion scalds, recent ploughing,<br />
grading or clearing.<br />
Low levels of vegetation and scrub cover. High incidence of ground surface<br />
visible due to recent or past land–use practices such as ploughing, grading and<br />
mining. Moderate level of ground surface visibility due to sheet wash erosion,<br />
erosion scalds and erosion scours.<br />
Very low to nonexistent levels of vegetation and scrub cover. High incidence of<br />
ground surface visible due to past or recent land use practices, such as<br />
ploughing, grading and mining. Extensive erosion such as rill erosion, gilgai,<br />
sheet wash, erosion scours and scalds.<br />
