Richness of Plant Species (seep. 7.5) <br />Count the number of plant species in the wetland that cover at ]cast 10 ft'.

Interspersion of habitats (seep. 76) <br />Decide from the diagrams below whether interspersion between Cowardin vegetation <br />classes (described in H I.I ), or the classes and unvegetated areas (can include open water or <br />muciflats) is high, medium, low, or none. <br />O O (:*) (* <br />_✓ None = 0 points =Low = I point Moderate = 2 points <br />.a <br />[riparian braided channels] <br />High = 3 points <br />NOTE: If you have four or more classes or three vegetation classes and open water <br />the rating is always "high".
