[2] A dead standing tree – known as a snag – provides many of the same functions as coarse woody debris. The minimum ...
Very coarse or very thick: >10 mm platy, granular; >50 mm blocky; >100 mm prismlike. Grades: Is a measure of the degree of development or cementation within the peds that results in their strength and stability.
