GROUND COVER (two-digit codes) 



Enter cover class code for each of the following types of 

 ground cover: 



S - bare soil (particles < 1/16 in. dia.) 



G - gravel (particles 1/16 to 3 in. dia.) 



R - rock (particles > 3 in. dia.) 



L - litter and duff. Litter includes freshly-fallen leaves, 

 needles, twigs, bark, fruits; duff is fermentation layer 

 and humus layer. 



W - wood (downed fragments > 1/4 in. dia.) 



M - moss. Also includes Lycopodium and Selaqinella . 



BV - basal vegetation. This is the area occupied by root 

 crowns and stems, not canopy cover. Values rarely exceed 

 30% and are usually lower. 



- other. Use when an additional category is needed. Iden- 

 tify the "other" item (e.g., lichen; water). 



Use the following cover classes and codes:

RIPARIAN FEATURES 



If the plot is within the riparian zone record the follov;ing 

 information (indicate units of measurement as appropriate): 



Channel Width (up to three-digit number) - if valley 

 contains multiple channels, give width of channel nearest 

 to the plot. 



Channel Entrenchment (up to three-digit number) - depth 

 to which channel has cut into valley floor. 



Surface Water (two-digit code) - estimate of maximum 

 ground cover of surface water on plot during the year 

 (use cover classes listed above under "Ground Cover").
