    Management Guidelines for Sage Grouse and Sagebrush Ecosystems in Nevada

    Get PDF
    These management guidelines and supportive background information promote the conservation of sage grouse (Centrocercus urophasianus) and their sagebrush (Artemisia spp) habitats on Nevada public lands administered by Bureau of Land Management (BLM). The guidelines are intended to provide interim guidance to field managers, without restricting options currently being explored for regional, state, and local sage grouse/sagebrush conservation planning. The guidelines are a Nevada BLM, habitat-specific, adaptation of the recently updated, and soon to be finalized, Western Association of Wildlife Agencies (WAFWA) Draft Guidelines. The Nevada BLM guidelines apply the most current sage grouse science to BLM activities, within the context of a multiple use mandate

    Diuron Ecological Risk Assessment

    The United States Department of the Interior (USDI) Bureau of Land Management (BLM) is proposing a program to treat vegetation on up to six million acres of public lands annually in 17 western states in the continental United States (US) and Alaska. As part of this program, the BLM is proposing the use of ten herbicide active ingredients (a.i.) to control invasive plants and noxious weeds on approximately one million of the 6 million acres proposed for treatment. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate this and other proposed vegetation treatment methods and alternatives on lands managed by the BLM in the western continental US and Alaska. In support of the EIS, this Ecological Risk Assessment (ERA) evaluates the potential risks to the environment that would result from the use of the herbicide diuron, including risks to rare, threatened, and endangered (RTE) plant and animal species. One of the BLM’s highest priorities is to promote ecosystem health, and one of the greatest obstacles to achieving this goal is the rapid expansion of invasive plants (including noxious weeds and other plants not native to the region) across public lands. These invasive plants can dominate and often cause permanent damage to natural plant communities. If not eradicated or controlled, invasive plants will jeopardize the health of public lands and the activities that occur on them. Herbicides are one method employed by the BLM to control these plants

    Rawlins RMP Biological Assessment

    Get PDF
    This Biological Assessment (BA) is prepared for the Draft Environmental Impact Statement (DEIS) that describes the comprehensive analysis of alternatives for the planning and management of public lands and resources administered by the Bureau of Land Management (BLM) in the Rawlins area of Wyoming. The public lands and federal mineral estate within the RFO Resource Management Planning Area (RMPPA) are the subject of the planning effort (DEIS) and this document. This document is a component of the BLM Draft Environmental Impact Statement Resource Management Plan (RMP) and is prepared in compliance with the National Environmental Policy Act (NEPA) which requires that an environmental impact statement be prepared for any federal actions that may significantly affect the human environment. The preparation and adoption of a RMP by the BLM is such a Federal action
