Book Description
This book documents nearly 500 US and Canadian locations where wildlife refuges, nature preserves, and similar properties protect natural sites that lie within the North American Great Plains, from Canada's Prairie Provinces to the Texas-Mexico border. Information on site location, size, biological diversity, and the presence of especially rare or interesting flora and fauna are mentioned, as well as driving directions, mailing addresses, and phone numbers or internet addresses, as available. US federal sites include 11 national grasslands, 13 national parks, 16 national monuments, and more than 70 national wildlife refuges. State properties include nearly 100 state parks and wildlife management areas. Also included are about 60 national and provincial parks, national wildlife areas, and migratory bird sanctuaries in Canada's Prairie Provinces. Many public-access properties owned by counties, towns, and private organizations are also described.

Book Description
This book examines the application of fish community characteristics to evaluate the sustainability and biological integrity of freshwaters. Topics include perspectives on use of fish communities as environmental indicators in program development, collaboration, and partnership forming; influence of specific taxa on assessment of the IBI; regional applications for areas where the IBI had not previously been developed; and specific applications of the IBI developed for coldwater streams, inland lakes, Great Lakes, reservoirs, and tailwaters.

Book Description
The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

Book Description
Revised, updated, and with more than 80 new color photographs, Rocky Mountain Mammals, Third Edition is a nontechnical guide to the mammals of the Southern Rocky Mountains and their foothills, with special emphasis on Rocky Mountain National Park and vicinity. Designed for quick reference and enjoyable reading, Rocky Mountain Mammals offers what most field guides don't - a wealth of fascinating information about each species. In seventy-two species accounts, David M. Armstrong describes each animal and its signs, habits, habitat, and natural history, noting times when seasonal events such as elk sparring occur. Introductory materials and appendices offer rich context and wildlife-watching support, including a checklist with page numbers for quick field reference, an identification key, a glossary, derivations of scientific names, and advice on how, when, and where to watch mammals. Armstrong introduces mammalian evolution, anatomy, and distribution and offers perspective on how the local fauna fits into its geographical setting and into past and potential future faunas of the region. This lavishly illustrated new edition will delight those who live in and visit the high country and foothills of the Southern Rockies and want to identify mammals and learn about their lives. Published in association with the Rocky Mountain Nature Association.
