Observed and predicted lichen biomass (g m⁻²) for each sample type and landcover type in northwestern Alaska.

Mean lichen biomass, estimated using the “All Taxa” regression slope coefficients from Table 2 and parceled out by landcover type, is reported with standard errors (in parentheses) and mean deviation from observed biomass. Mean deviation is interpreted as measurement error. Landcover type codes: L = Dwarf Shrub-Lichen Dominated; M = Mesic/Dry Herbaceous; P = Open Low Shrub Dwarf Birch/Ericaceous; S = Sparse Vegetation. Caution: these biomass values were based on average quadrat cover >80% and should not be considered an inference about areas >1 m2 (which could have erratic cover).
