Animas River downstream from Silverton, Colorado, showing right and left bank areas where streambed sediment sample was collected near USGS stream gage at site A72 (USGS site ID 09359020). Latitude 37.789964, Longitude -107.667394.

Determining aboveground biomass of sagebrush, grasses, and forbs is important for estimating fuel loads, measuring carbon storage, and assessing habitat quality in shrublands. Remote sensing may offer a more efficient alternative to common, labor intensive methods of measuring aboveground biomass that are difficult to apply across large areas.
