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