used by particular species, such as osprey. Table 5-17 shows the scores for the

WRAP variables and final score out of a 0 to 1 score range for the seepage buffer

habitat. For the littoral shelf, the team used only those WRAP variables that

were applicable to the habitat. The scores for Littoral Shelf Habitat are shown

in Table 5-18.

To convert these scores to Habitat Units, they were multiplied by the acreage of

the buffer area. Table 5-19 shows the habitat units lift incurred with additional

project costs.
