Description

Definition

Organic substrate is primarily composed of coarse organic material that is relatively intact, with a median particle size from 4 millimeters to < 4,096 millimeters (the size of Pebbles, Cobbles, and Boulders). Organic Debris that is larger than that (e.g., whale falls, tree falls) is covered in the Geoform Component.
