Pocket Gopher Food Habits on Two Disturbed Forest Sites in Central Arizona (Classic Reprint) by Gerald J. Gottfried Pdf

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.

Pocket Gopher Food Habits on Two Disturbed Forest Sites in Central Arizona by Gerald J. Gottfried Pdf

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.

Conservation by Proxy by Tim Caro Pdf

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.

Big Sagebrush by Bruce Leigh Welch Pdf

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.

Wildlife Habitat Management by Brenda C. McComb Pdf

In recent years, conflicts between ecological conservation and economic growth forced a reassessment of the motivations and goals of wildlife and forestry management. Focus shifted from game and commodity management to biodiversity conservation and ecological forestry. Previously separate fields such as forestry, biology, botany, and zoology merged
