Affected Environment The Gila National Forest (GNF) is situated within four river basins, the Gila-San Francisco, Mimbres, Little Colorado, and Rio Grande. Among them, species diversity, richness, and endemism are variable and depend, in part, on geologic history, relative proximity to more mesic and species-rich regions, climatic factors, and relative size and complexity of each drainage (Propst, 1999). The GNF has three manmade lakes completely or partially on National Forest lands and hundreds of miles of streams within one hundred-eighty 6th code watersheds. Aquatic features found on the GNF include both lotic (moving water) and lentic (still water) systems. There are over 1700 miles of perennial and intermittent stream habitat that occur in watersheds of the Gila National Forest within the project area. These streams contain a variety of aquatic species (see table 29 for federally listed species and table 47 for Region 3 sensitive species), most significant of which are those native resident species that are key for aquatic habitat management. These species’ designations as endangered, threatened, sensitive and/or as management indicator species (MIS) emphasize the need for not only conservation, but also recovery efforts as part of interagency management programs throughout the project area. Relevant Laws, Regulations, and Policy Forest Service Manual 2670 and Forest Service Handbook 2609.25 provide direction regarding Forest Service sensitive species, which are identified by the Regional Forester. The Forest Service develops and implements management practices to ensure that rare plants and animals do not become threatened or endangered, and ensure their continued viability on National Forests. The Endangered Species Act of 1973 (16 USC 1531 et seq.) states that each Federal agency shall, in consultation with and with the assistance of the Secretary insure that any action authorized, funded, or carried out by such agency is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat of such species. Section 7 of the ESA, as amended, requires the responsible federal agency to consult the U.S. Fish and Wildlife Service concerning threatened or endangered fish species under their jurisdiction. There are five fish species that are listed under the Endangered Species Act on the GNF: loach minnow, spikedace, Gila chub, Chihuahua chub, and Gila trout. Gila National Forest Land and Resource Management Plan identified the following relevant management standards and guidelines for fisheries resources across the entire forest: C01, C11: Manage threatened, endangered, and sensitive animal, fish, and plant habitat to achieve delisting in a manner consistent with the goals established with the U.S. Fish and Wildlife Service and the New Mexico Department of Game and Fish in compliance with approved recovery plans. C02: Manage riparian areas to protect the productivity and diversity of riparian dependent resources by requiring actions within or affecting riparian areas to protect and where applicable, April 2013 – Gila National Forest Page - 5 - Implementation of the Travel Management Rule Implementation – Gila National Forest improve dependent resources. Emphasize protection of soil, water, vegetation, and wildlife and fish resources prior to implementing projects. C02: Give preferential consideration to resources dependent on riparian areas over other resources. Other resource activities may occur to the extent that they support or do not adversely affect riparian dependent resources. C02: Wildlife coordination and improvement efforts will include emphasis on riparian and aquatic area management. L04, L05: Road construction will be avoided in riparian areas. LRMP standards and guidelines related to water quality are displayed in the Hydrology section. Methodology and Analysis Process Analysis Framework The project area includes all NFS lands within the administrative boundary of the Gila National Forest. The geographic extent of the direct, indirect, and cumulative effects analysis is generally confined to aquatic features of watersheds within this administrative boundary. The area of analysis was chosen based on the potential for motorized routes on NFS lands to affect aquatic systems. It assumes that motorized routes located in watersheds on the GNF that influence larger riverine systems could have a measurable influence on these systems immediately adjacent to and downstream of the Forest. Therefore, this analysis will focus

  • Rio Costilla Habitat Improvement Project
    Decision Memo Rio Costilla Habitat Improvement Project USDA Forest Service, Southwestern Region Questa Ranger District, Carson National Forest Taos County, New Mexico (Sections 1, 2, 11, 12, 14, and 15 of Township 30 North, Range 15 East) Background An interdisciplinary analysis on this project was conducted and is documented in a project record. Source documents from the project record are incorporated by reference throughout this decision memo by showing the document number in brackets [PR #]. Please refer to Appendix A for the project record index. The Questa Ranger District of the Carson National Forest, in partnership with the New Mexico Department of Game and Fish (NMDGF) and the U.S. Fish and Wildlife Service, proposes to improve in- stream habitat conditions within the Rio Costilla [PR #77, 128]. The Valle Vidal Unit of the Carson National Forest attracts hundreds of anglers annually. The Rio Costilla is the largest stream in the Valle Vidal and a favorite among anglers. Anglers travel to this area in large part to pursue the native Rio Grande cutthroat trout. Long-term operations of the Costilla Reservoir and Dam have channelized the Rio Costilla, which has become inadequate for holding fish during low-flow conditions and through the winter. The Rio Costilla has become shallow and wide in many spots, and future efforts to re-establish self-sustaining populations of Rio Grande cutthroat trout may not be successful without active management. Since 2001, Rio Grande cutthroat trout and other native fish population restoration efforts have been ongoing within the upper Rio Costilla watershed. Restoration efforts in this section of the Rio Costilla have included the construction of the Rio Costilla terminal fish barrier in October 2016.

Your original request was dated November 24, 2000, and received in our office November 27, 2000. Due to changes made in the proposed action, your office resubmitted the biological evaluation on March 12, 2001. Thus, formal consultation commenced on that date. At issue are impacts that may result from the Tucson Field Office’s grazing program in portions of the Middle Gila River Ecosystem, Gila and Pinal counties, Arizona. These impacts may affect the following listed species: southwestern willow flycatcher (Empidonax traillii extimus); cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum); lesser long-nosed bat (Leptonycteris curasoae yerbabuenae); spikedace (Meda fulgida); and loach minnow (Tiaroga cobitis), and critical habitat designated for the spikedace and loach minnow. The Bureau of Land Management (BLM) requested our concurrence that the proposed action may affect, but is not likely to adversely affect, the Arizona hedgehog cactus (Echinocereus triglochidiatus var. arizonicus) and the bald eagle (Haliaeetus leucocephalus). We concur with the BLM’s determinations for these species.

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.
