The author has identified the following significant results. Crested wheatgrass seedings have been quantified for the state of Nevada, and have been broken down by county and land status. The wide coverage of ERTS-1 has been found to be extremely useful for putting these seeded areas in the proper perspective for inventory. In the same manner, water bodies are being inventoried and changes relating to time are being monitored. Water resources are critical in Nevada, and this should prove useful to land owners and land managers throughout the state.
