Seneca Coal Company, Routt Co., CO - 2011
FIRST HIT ALL HIT
*P= Present within 1 m. on either side of cover transect, but not quantitatively encountered.
() =Data in parens. = 2nd hits. A 1st hit is top -most layer of vegetation, below 1st hit interceptions may exist other interceptions - these are 2nd hits.
