Potential sediment losses in meadow and forested ecosystems proved statistically similar, ranging from 15 to 217 kilograms per hectare (13.4-193.6 pounds/acre). In dry grassland ecosystems potential sediment production was similar to that in most forested ecosystems with the exception of the larch ecosystem. Potential sediment production in the larch ecosystem also differed from that in the meadow ecosystem. The grassland ecosystem produced a potential sediment loss of 431 kilograms per hectare (384.5 pounds/acre). Sagebrush and juniper eco-systems showed potential sediment losses exceeding the losses in all other ecosystems with rates of 1,284 and 1,572 kilograms per hectare (1,45.6 and 1,402.5 pounds/acre), respectively. As ecological condition class and/or vegetative productivity class changed within ecosystems, statistically significant changes in potential sediment production occurred. ER -
