table of pools and the strata they contain
Percent cover measures the amount of area rooted floating leaf and emergent species cover based on a cover rating. It is calculated using the following formula:
Where L j is the cover rating at individual sites and A is the midpoint of the corresponding percent cover, and M is the total number of sites in the stratum.
