Summary

Critical habitat constitutes areas considered essential for the conservation of a listed species. These areas provide notice to the public and land managers of the importance of the areas to the conservation of this species. Special protections and/or restrictions are possible in areas where Federal funding, permits, licenses, authorizations, or actions occur or are required.

Description

These data identify, in general, the areas of Final critical habitat for Astragalus magdalenae var. peirsonii (Peirson's milk-vetch).

Use limitations

The GIS files and their associated coordinates are not the legal source for determining the critical habitat boundaries of species described in this dataset, but are used to identify areas which contain the physical and biological features essential to the conservation of the species or areas otherwise determined to be essential. Inherent in any dataset used to develop graphical representations, are limitations of accuracy as determined, among others, the source, scale and resolution of the data. While the U.S. Fish and Wildlife Service makes every effort to represent the critical habitat shown with data as completely and accurately as possible (given existing time and resource constraints), the USFWS gives no warranty, expressed or implied, as to the accuracy, reliability, or completeness of these data. In addition, the USFWS shall not be held liable for improper or incorrect use of the data described and/or contained herein. Graphical representations provided by the use of these data do not represent a legal description of the critical habitat boundary. The user is referred to the critical habitat textual description in the appropriate final rule for this species as published in the Federal Register. These data are to be used only in the context of the definition and purpose of critical habitat. This primarily relates to Section 7 consultation under the Endangered Species Act. These data may be used for planning and land management purposes. They are not to be used for legal survey use.

Description
The Bureau of Land Management conducted extensive sensitive plant surveys through the full extent of the Algodones Dunes during Spring 2005. The BLM surveys compiled data in adjacent 25 X 25-meter cells along 4-5 Km survey transects throughout the dunes. A total of 123,488 cells were surveyed in 2005 along transects totaling 1,922 miles (3,095 km). The GIS model defining Peirson's milk-vetch designated critical habitat is based upon the 2005 BLM survey data. We selected occupied survey cells with a plant density greater than 480 plants per hectare (ha) (30 plants per cell) (192 plants per acre) as core areas. We used a density of 480 plants per ha since this captured the majority of the large clusters of standing plants. We expanded each core area (25 X 25-m cell) to 2 ha, then merged the 2-ha core areas within 100-m proximate of each other to form aggregated core areas. Outlying or remote core areas greater than 400 meters from adjacent core areas and core areas less than 400 m away but with a plant density less than approximately 370 plants (=0.0005 of the total observed population of 739,805) within the aggregated core area. This step allowed us to remove core areas with low numbers of plants considered not essential to the conservaiton of the species. We then overlaid a 100-meter UTM NAD83 grid onto the final core areas to define the legal boundaries. This methodology captured approximately 92 percent of the 2005 observed population and includes areas we believe contain high density core populations, a large extent of high quality habitat, and a large seed bank and, therefore, areas important for the recovery of the species.
