Book excerpt: Excerpt from Pocket Gopher Food Habits on Two Disturbed Forest Sites in Central Arizona Although grass seeding provides rapid revegetation, it also improves gopher habitat. Therefore, grass should be seeded only where erosion is a problem and where range and wildlife benefits are the prime consideration. It is difficult and expensive to reduce natural or seeded vegetation and the associated pocket gopher (thomomys bottae) populations once they occupy a site; but vegeta tion control may reduce both problems.

Book excerpt: Stomach analysis of pocket gophers (Thomomys bottae) indicated that on one area succulent grasses were the main food item, supplying between 84% and 44 % of the average composite diet. Bromegrasses (Bromus spp.) were highly preferred. Thistle (Cirsium spp.) was the main forb eaten. The second area supported a forb-grass-brush cover after the forest had been removed. Forbs comprised about 70% of the herbaceous cover, and supplied 51% of the diet; grasses and sedges (Carex spp.) averaged 25% of the diet. Fleabane (Erigeron spp. and common sunflower (Helianthus annus) were the main forbs in the diet. Wood material, including ponderosa pine (Pinus ponderosa) was not used heavily throughout the period, although use did increase slightly during the winter. Insects were between 8% and 19% of the average diet.

Download or read book Big Sagebrush written by Bruce Leigh Welch and published by . This book was released on 2005 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pioneers traveling along the Oregon Trail from western Nebraska, through Wyoming and southern Idaho and into eastern Oregon, referred to their travel as an 800 mile journey through a sea of sagebrush, mainly big sagebrush ( Artemisia tridentata). Today approximately 50 percent of the sagebrush sea has given way to agriculture, cities and towns, and other human developments. What remains is further fragmented by range management practices, creeping expansion of woodlands, alien weed species, and the historic view that big sagebrush is a worthless plant. Two ideas are promoted in this report: (1) big sagebrush is a nursing mother to a host of organisms that range from microscopic fungi to large mammals, and (2) many range management practices applied to big sagebrush ecosystems are not science based.

Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
