Final Report –July 2005
EXECUTIVE SUMMARY
1. The purpose of this report is to assess the potential economic impacts associated with the designation of critical habitat for the Roswell springsnail, Koster’s springsnail, Pecos assiminea, and Noel’s amphipod (four invertebrates) and their habitat. This analysis is consistent with the designation as described in the proposed rule. As such, this analysis does not reflect potential changes to the proposed critical habitat designation (CHD) in the final rule. Description of the critical habitat in the final rule may consequently differ from that presented in this analysis. This report was prepared by Industrial Economics, Incorporated for the Service.
2. This report attempts to quantify the economic effects associated with the proposed designation of critical habitat. It does so by taking into account the cost of conservation- related measures that are likely to be associated with future economic activities that may adversely affect the habitat within the proposed boundaries.
3. The four invertebrates are aquatic species native to natural springs, sinkholes, and associated spring runs in dry regions of Chaves County, New Mexico and Pecos and Reeves Counties, Texas. The Service has proposed to designate four units of critical habitat for the four invertebrates. The proposed units encompass 1,524 acres of land within Bitter Lake National Wildlife Refuge in Chaves County, New Mexico and on The Nature Conservancy lands in Pecos and Reeves Counties. All lands proposed as critical habitat are currently occupied by at least one of these invertebrate species.
4. Approximately 74 percent of the proposed CHD occurs on the Bitter Lake National Wildlife Refuge, a refuge managed by the Service to protect and provide habitat for a number of species. The remaining 26 percent of the proposed CHD occurs on lands managed by The Nature Conservancy as preserves.
5. Section 4(b)(2) of the Endangered Species Act (Act) requires the Service to designate critical habitat on the basis of the best scientific data available, after taking into consideration the economic impact, and any other relevant impact, of specifying any particular area as critical habitat. The Service may exclude areas from critical habitat designation when the benefits of exclusion outweigh the benefits of including the areas within critical habitat, provided that exclusion will not result in extinction of the species.
Results of the Analysis
6. This analysis considers impacts of conservation measures within Units 1 and 2, both managed by the Bitter Lake National Wildlife Refuge in New Mexico and separated by a few hundred meters, and within Units 3 and 4, which are both managed by The Nature Conservancy in Texas. This analysis focuses on quantifying impacts to activities most likely to be affected by the proposed critical habitat designation. These activities include:
