WILDLIFE New Water Mountains Wilderness SERVICE lnteragency Management Plan , . f.~.\-,. ' t ,~.\ \ and Environmental Assessment j ' ' The Bureau of Land Management is responsible for the balanced management of the public lands and resources and their various values so that they are considered in a combination that will best serve the needs of the American people. Management is based upon the principles of multiple use and sustained yield; a combination of uses that take into account the long term needs of future generations for renewable and nonrenewable resources. These resources include recreation, range, timber, minerals, watershed, fish and wildlife, wilderness and natural, scenic, scientific and cultural values. The U.S. Fish and Wildlife Service is an agency of the Department of the Interior with a two-fold mission: to protect and manage wildlife in the interest of the American people and to provide wildlife oriented recre­ ational and educational opportunities to the American people. The Service currently manages the National Wildlife Refuge System, many National Fish Hatcheries, and several wildlife research centers. Additionally, it monitors and protects endangered species; provides tech­ nical help to international, federal, state and local agencies, Native American tribes, and private landown­ ers on fish and wildlife matters; administers a program of federal monetary aid to state wildlife agencies; and enforces federal laws and regulations to protect wildlife and their habitats.

Impacts expected from implementing the proposed plan are analyzed in the Environmental Assessment. The Plan will provide long-term management guidance for the Kofa National Wildlife Refuge and New Water Mountains Wilderness. A draft version of this document was released for public review and comment in January 1996. Comments on the draft plan were analyzed and revisions were made for inclusion in the final document where appropriate. A compilation of the comments is available upon request. The Environmental Assessment and Decision Record are subject to appeal in accordance with procedures contained in 43 Code of Federal Regulations, Part 4, Subparts E and G. Implementation of this plan will not begin until 30 days after the date of this letter. The Kofa National Wildlife Refuge and Yuma Field Office staffs thank all who contributed to the development of this document. We encourage your continued participation in the effort to ensure that our natural resources are properly managed for current and future generations.

    DEPARTMENT OF THE INTERIOR U.S. FISH AND WILDLIFE SERVICE REGION 2 DIVISION OF ENVIRONMENTAL CONTAMINANTS CONTAMINANTS IN BIGHORN SHEEP ON THE KOFA NATIONAL WIL DLIFE REFUGE, 2000-2001 By Carrie H. Marr, Anthony L. Velasco1, and Ron Kearns2 U.S. Fish and Wildlife Service Arizona Ecological Services Office 2321 W. Royal Palm Road, Suite 103 Phoenix, Arizona 85021 August 2004 2 ABSTRACT Soils of abandoned mines on the Kofa National Wildlife Refuge (KNWR) are contaminated with arsenic, barium, mercury, manganese, lead, and zinc. Previous studies have shown that trace element and metal concentrations in bats were elevated above threshold concentrations. High trace element and metal concentrations in bats suggested that bighorn sheep also may be exposed to these contaminants when using abandoned mines as resting areas. We found evidence of bighorn sheep use, bighorn sheep carcasses, and scat in several abandoned mines. To determine whether bighorn sheep are exposed to, and are accumulating hazardous levels of metals while using abandoned mines, we collected soil samples, as well as scat and bone samples when available. We compared mine soil concentrations to Arizona non-residential clean up levels. Hazard quotients were elevated in several mines and elevated for manganese in one Sheep Tank Mine sample. We analyzed bighorn sheep tissues for trace elements. We obtained blood, liver, and bone samples from hunter-harvested bighorn in 2000 and 2001. Arizona Game and Fish Department also collected blood from bighorn during a translocation operation in 2001. Iron and magnesium were elevated in tissues compared to reference literature concentrations in other species. Most often, domestic sheep baseline levels were used for comparison because of limited available data for bighorn sheep.

The first one consists of a series of intercalations of calc-silicate rocks, local marbles, and greenschist. Quartzite appears in the upper part of the section. This section passes transitionally to the gneiss, which is believed to be of sedimentary origin. Features indicative of sedimentary origin include inter­ calation with marble, relic bedding which can be observed locally, intercalation of greenschist clearly of sedimentary origin, lack of homogeneity in composition with both lateral and vertical variation occurring, roundness of zircon grains, and lack of zoning in the feldspars.

(Junonia coenia on Helianthus annuus) important ecological but threatened riparian landscapes (Provencher et al. 2005). Not only does the Warm Springs Natural Area encompass the majority of Muddy River tributaries it is also the largest single tract of land in the upper Muddy River set aside for the benefit of native species in perpetuity. The prominence of water in an otherwise barren Mojave landscape provides an oasis for regional wildlife. A high bird diversity is attributed to an abundance of riparian and floodplain trees and shrubs. Contributions to plant diversity come from the Mojave Old World swallowtail (Papilio machaon) Desertsnow (Linanthus demissus) Lobe-leaved Phacelia (Phacelia crenulata) Cryptantha (Cryptantha sp.) vegetation that occur on the toe slopes of the Arrow Canyon Range from the west and the plant species occupying the floodplain where they are supported by a high water table. Several marshes and wet meadows add to the diversity of plants and animals. The thermal springs and tributaries host an abundance of aquatic species, many of which are endemic. The WSNA provides a haven for the abundant wildlife that resides permanently or seasonally and provides a significant level of protection for imperiled species.

  • BLM Public Land Statistics 2007
    Click Here for Table of Contents PUBLIC LAND STATISTICS 2007 Volume 192 BLM/OC/ST-08/001+1165 May 2008 WELCOME TO PUBLIC LAND STATISTICS 2007 Welcome to the 2007 edition of Public Land Statistics, published by the U.S. Department of the Interior, Bureau of Land Management (BLM). As in years past, the cover of this year’s publication is designed to convey the scope of the Bureau’s complex and multifaceted mission using visual imagery. The 80-plus tables inside the document tell the story of the BLM’s mission, programs, and accomplishments using numerical data and detailed footnotes. Many of the minor acreage changes from 1 year to the next occur because: 1. Inholdings have been acquired or some other land exchange has taken place during the year. 2. Better GIS mapping of land boundaries has enabled us to recalculate the total BLM acres within the unit. Public Land Statistics is available on the Internet. Please visit our national homepage at: http://www.blm.gov/public_land_statistics/index.htm . Note that the data presented in the 2007 Public Land Statistics tables may not exactly match the data in other BLM publications covering Fiscal Year 2007 operations and accomplishments. This occurs because the databases that provide table data are not static; they are constantly being updated to provide the latest information, sometimes many months after the end of the fiscal year. We have presented the most current data available in this edition of Public Land Statistics. We remain committed to publishing a Public Land Statistics report each year that is timely, complete, and helpful as possible to our readers.
