Riparian Vegetation = plant species comprising riparian vegetation
Crown Cover = % of wetted channel covered by vegetation
In-Stream Vegetation = emergent and submergent plant species
Location of Riparian Vegetation:
Y= major growth located on critical west or south banks
N= no vegetation or major growth located on east or north banks
