Forest Cover Data

Forest cover grades for each subwatershed are based on forest cover and interior forest. Grades for each of these were averaged to obtain a final grade.

To calculate the grades, percentage ranges for forest cover and interior forest were assigned points that corresponded to specific grades.

Forest Cover (%)	Point Score	Grade
>25.6	5	A
26.6 - 18.8	4	B
18.7 - 11.9	3	C
11.8 - 5.0	2	D
<5.0	1	F

Forest Interior (%)	Point Score	Grade
>7.7	5	A
5.7 - 7.7	4	B
3.7 - 5.6	3	C
1.7 - 3.6	2	D
<1.7	1	F

For example, if a subwatershed has 15% forest cover it would score a 3 and a letter grade of C. If the same subwatershed has 2% forest interior it would receive a score of 2 and a letter grade of D. For the final grade, the average of the two scores (3+2)/2 = 2.5 would result in a C (rounding up to the nearest whole number).
