      The relationship between live and dead biomass of blue grama and acetone extractable pigments was determined to assess its utility in predicting live and dead proportions of a mixed sample. We found the technique to be useful and recommend its use when exact separation is not required. Biomass dynamics of blue grama do not usually fit a parabolic model. Much of the variability in live biomass of blue grama can be explained by rainfall pattern during the growing season.
