NOTES:
BAT = total aboveground biomass; DBH = diameter at breast height; DBA = stem basal diameter; HT = tree height
In cases where dbh was needed but dba was measured, dba was multiplied by 0.9
In cases where dba was needed but dbh was measured, dbh was multiplied by 1.1
In the ONE case where percent cover was needed (Mimulus), DBA was multiplied by .001 to simulate percent cover.
In equations where height was required, heights were estimated using lidar  trees noted as "upper" canopy were assigned the maximum height measured in the plot, trees noted as "mid" canopy were assigned max ht * 0.5, trees noted as "lower" were all designated as 2.5 m tall. Shrubs were designated as 1.5 m tall.
Bold "Source Species / Types" are categories from Jenkins et al., 2003, applied only where no other appropriate equation could be found.
Original Pillsbury (1984) equations were for volume in cubic meters, so they are converted to biomass by multiplying by wood density from Preston et al (2006) in kg m3
* = Species equivalence (or or a congener) used in Riccardi et al. 2007
** = Equation applied to congeners in Jenkins 2002
% = Listed in BIOPAK as C. stolonifera, but these species are the same and C. sericea is current according to plants.usda.gov
# = source from BIOPAK (Means et al. 1994)
