Block 6-7
The erosion condition composite SSF score for this site was 14, which placed it in the
Stable erosion class. The tabulated results for this s urvey are contained in Table 1 4. Rills and
gullies are stable with vegetation growing on the sides and bottoms of feature s. In 2002,
corrective measures inc luded contour furrowing and seeding a gully located at the southwest
'
edge of the block. No corrective measures planned as a result of the inventory.
