AbstractRadar remote sensing of rangelands offers new possibilities for monitoring and managing a valuable renewable resource which has low unit productivity, A study was conducted on a mixed Prairie site in 1991 to examine the effects of clipping and fertility on the ability to detect range differences in radar backscatter. The data showed that radar backscatter was most sensitive to changes in soil moisture content although there was some sensitivity to clipping and fertilizer treatments. These results indicate that useful information about rangeland resources may be extracted from SAR data especially when used in combination with visible and near infra-red reflectance.
