Block 7-8
The erosion condition composite SSF score for this site was 11, which placed it in the
Stable erosion class. The tabulated results for this survey are contained in Table 15. Old gullies
in this area show no sign of new erosion. No corrective measures planned as a result of the
inventory.

Block 8-9
The erosion condition composite SSF score for this site was 17, which placed it in the
Stable erosion class. The tabulated results for this survey are contained in Table 16. Rills and
gullies are stable with little evidence of soil movement and vegetation growing on the sides and
bottoms of features. Some gullies have been identified for repair in 2004.
