The attenuation of beta radiation by prairie standing crop was measured in quadrats which were also harvested. Attentuation and harvest measurements were made at weekly intervals and at five sites differing in soil type and/or burning treatment. Attenuation measurements were made within each quadrat accross both the vertical and horizontal dimensions. Living and dead biomass were separated at harvest for dry weight determinations. Attenuation measurements are excellent predictors of standing crop. The vertical profile of measurements may be used to determine foliage height diversity. Patterns of temporal and spatial heterogeneity in vegetation are also shown by this particular set of measurements
