Informal Trails Mapping

A growing repository of high-resolution satellite and aerial imagery provides a promising opportunity for monitoring the spread of recreational trails and their ecological impacts. The project is in collaboration with the Bureau of Land Management, and uses geospatial methods and data sources to provide baseline data on formal and informal trail proliferation along the Owyhee front in southwestern Idaho. The target mapping locations are centered around monitoring sites for Mulford's Milkvetch (Astragalus mulfordiae), a rare and threatened plant endemic to southwestern Idaho and eastern Oregon.
