In 2001, a Desert Monitoring Team was hired by the Bureau of Land Management to monitor the effects of Off-Highway Vehicles (OHV's) on the desert ecosystem. One of their tasks was to develop a monitoring protocol for birds and to begin that monitoring. After a year of pilot surveys and adjustments, a final protocol was completed in the fall of 2002. The protocol calls for 3 surveys each year: a December survey in the creosote scrub away from roads, a February survey in the creosote scrub away from roads, and a May survey in the same locations as the December survey. Each survey lasts for 2 weeks and is comprised of 70 transects. Half of these transects are in OHV areas (the Jawbone-Butterbredt ACEC and the Rand Mountain/Freemont Valley Management Area) and the other half are in non-OHV areas (the Golden Valley Wilderness, the Grass Valley Wilderness and Desert Tortoise Natural Area), which serve as controls. This document describes steps taken as well as the survey results.
