Purple Martin Monitoring After a Wildfire in the Lincoln National Forest, New Mexico: 2006 Results.

摘要

In 2000, a wildfire burned approximately 6,500 ha of coniferous forest in the Lincoln National Forest in south-central New Mexico. During general point count surveys in four years following the fire (2002-2005), Hawks Aloft documented Purple Martins among the species using snags in burned areas of the forest. In 2006, Hawks Aloft received funding support from the USDA Forest Service and the Purple Martin Conservation Association to locate and monitor Purple Martin colonies. Based on previous detections of Purple Martins, we searched ten select areas to (1) identify Purple Martin colony sites, (2) determine specifications of snags used by Purple Martins, and (3) establish an easily repeated framework for determining temporal trends in Purple Martin numbers.
