TABLE 3.
Models of biomass in monoculture plots. Only models using planted cover and those using uncorrected VIs are shown, as well as models mentioned in the text. See Supplement 10 (available on GitHub and Zenodo, see Data Availability statement) for all models.

— = no covariate was used; AIC = Akaike’s information criterion; ∆AIC = the difference between the AIC of the best model evaluated for that test and the model being reported; GDVI2 = generalized difference vegetation index; GNDVI = green normalized difference vegetation index; GRE = green; NDVI = normalized difference vegetation index; NIR = near infrared; REG = red edge; VI = vegetation index.
