Technical Abstract: Aerial photos are a type of remote sensing data especially valuable for rangeland applications. This type of data has advantages that include relative ease of interpretation and acquisition, inexpensiveness, high resolution (1-2m), and providing a common reference for communication among those involved in rangeland management. Additionally, air photos are especially well suited for analysis of historical rangeland remediation treatments because acquisition of widespread aerial photographic coverage began during the 1930's. Several types of treatments are easily identified and monitored over time, including contour terraces, brush water spreaders, rootplow seeding, water ponding dikes, shrub removal by grubbing, and grazing restrictions. The use of aerial photos allows us the opportunity to recreate the management history of rangeland and to serve as a point of departure for involvement in more sophisticated satellite-based remote sensing systems.
