    Rich, T. 2005. Long term changes in breeding bird populations and habitat, Laidlaw Park, Craters of the Moon National Monument, ID. U.S. Fish and Wildlife Service. Boise, ID.

    Abstract:  From 2002-2004, Terry Rich re-sampled a series of line transects that he had established in 1981 to evaluate the occurrence and density of breeding birds in the Craters of the Moon National Monument.  Transects were read from 1981-1984 and re-read from 2002-2004.  Seven transects were re-read in three different communities: big sagebrush (Artemisia tridentata tridentata), three tip sagebrush (A. tripartita), and cheatgrass (Bromus tectorum).  All of the transects overlap with the Pioneer Mountain Ranch operating area including: Paddelford Flat, Laidlaw Park, and Wildhorse allotments.  Birds were sampled using the point count method; the line intercept method was used to assess vegetation.  Transects were permanently marked with fence posts and their locations were GPS’d.  This study was cooperatively funded by Lava Lake, BLM, and USFWS.   

    Results indicate that several songbirds (Brewer’s sparrow, sage thrasher, vesper sparrow, Western meadowlark, and horned lark) that have shown population declines regionally have shown increases or smaller declines within the Laidlaw Park study area.
