Feral burro populations: Distribution and damage assessment

PDF Version Also Available for Download.

Description

This report was prepared to document (1) regional use of the National Training Center (NTC), Fort Irwin, CA, by burros, (2)influence of available water sources for burro use, (3) burro-related damage at several NTC sensitive habitat areas, and (4) management recommendations. All work described in this report was conducted in 1996 and 1997. Roadside transects were conducted and mapped using Geographical Positioning Systems/Geographical Information Systems (GPS/GIS) to indirectly measure relative abundance of feral burros (scat per mile) and to examine the spatial relationship of burro use to permanent or semi-permanent water sources that exist on the NTC. The authors also ... continued below

The authors also surveyed several permanent springs for burro-related damage and mapped the impact areas using GPS/GIS to quantify the extent of damage and to provide guidance on size and extent of burro exclosures in those areas. Photographs of the spring sites were also archived and permanent photo points were established for long-term monitoring of feral burro damage areas. In addition, aquatic invertebrate data collected during another spring site study were summarized and discussed in relation to burro-related impacts on the NTC`s sensitive habitats. Several water-quality parameters were also obtained from each spring, including temperature, dissolved oxygen, pH, and total dissolved solids.
