Book Description
Due to loss of habitat, Gunnison sage-grouse (Centrocercus minimus) currently occupy 8.5% of their presumed historical range. One population survives in Utah, occurring in San Juan County. The Gunnison Sage-grouse Rangewide Conservation Plan and the San Juan County Gunnison Sage-grouse Conservation Plan recommended management strategies to address identified conservation threats to the Utah population. I addressed three conservation strategies identified in the plans: 1) creation and enhancement of brood-rearing areas; 2) assessment of habitat conditions within the Gunnison Sage-grouse Conservation Area; and 3) prevention or reduction of perching events by avian predators on distribution line power poles. From 2007-2009, I addressed the conservation strategy of creating mesic broodrearing areas in Conservation Reserve Program fields and native sagebrush areas by evaluating the role of irrigation and dormant season cattle grazing on habitat. Vegetation and arthropod diversity in irrigated versus non-irrigated plots did not differ (p>0.01). Conservation Reserve Program plots exhibited greater arthropod abundance and cover of perennial grass than the native sagebrush plots, but lower diversity of perennial grasses and abundance and diversity of forbs (p

Book Description
This draft resource management plan amendment and environmental impact statement has been prepared by the Bureau of Land Management (BLM) with assistance from 21 cooperating agencies. It describes and analyzes four alternatives for managing approximately 741,700 acres of BLM administered land and nearly 1.35 million acres of BLM-administered subsurface federal mineral estate that may lie beneath other surface ownership. Surface estate and federal mineral estate is managed by seven BLM field offices (Grand Junction, Gunnison, San Luis Valley, Tres Rios and Uncompahgre in Colorado and Moab and Monticello in Utah), three national conservation areas (Dominguez-Escalante, Gunnison Gorge and McInnis Canyons) and Canyons of the Ancients National Monument. The analysis area spans portions of 12 counties: Chaffee, Delta, Dolores, Gunnison, Hinsdale Mesa, Montrose, Ouray, Saguache, and San Miguel in Colorado and Grand and San Juan in Utah. The alternatives present a range of management actions to achieve the goal of Gunnison Sage-Grouse conservation for BLM Colorado and Utah.

Book Description
Until now there has been no single, comprehensive resource on the status of North America's most threatened birds and what people can do to help protect them. Birder's Conservation Handbook is the only book of its kind, written specifically to help birders and researchers understand the threats while providing actions to protect birds and their habitats. Jeffrey Wells has distilled vast amounts of essential information into a single easy-to-use volume-required reading for anyone who loves birds and wants to ensure they are protected. At-a-glance species accounts cover in detail North America's one hundred most at-risk birds; each account is beautifully illustrated by today's top bird artists. The text includes status, distribution, ecology, threats, conservation actions and needs, and references. A distribution map accompanies each entry. Chapters discuss birds as indicators of environmental health, the state of North American bird populations, major conservation issues, and initiatives now underway to improve the health of North America's birds. Birder's Conservation Handbook is an indispensable resource for birdwatchers, researchers, naturalists, and conservationists. Reading it will inspire you to become an active steward of our birds and the habitats we share. A comprehensive guide to North America's one hundred most at-risk birds and how to protect them Compact and easy to use, with beautiful illustrations and data organized for convenient, at-a-glance reference Detailed species accounts, including distribution maps Practical advice on conservation Information on leading conservation agencies and resources
