Book excerpt: Woodland caribou (Rangifer tarandus caribou) are an iconic species of boreal and montane ecosystems, but many populations are declining due to habitat alteration and associated changes in predator-prey dynamics. Summer forage, however, influences lactation, juvenile growth, pregnancy, and survival, thereby affecting individuals and populations. I used tame caribou (of three nutritional classes - lactating, non-lactating, yearling) as a habitat assessment tool, at 135 sites across northeastern British Columbia, to determine: food habits and selection; dry matter intake rates; diet quality; and daily nutrient intakes. My goal was to assess the suitability of nutritional resources in boreal and montane plant communities to support energy and protein requirements of caribou during summer. Caribou were highly selective foragers. Deciduous shrubs were the primary summer forage of caribou; forbs, lichens, and mushrooms were secondary dietary items. Intake rates by caribou increased with increasing bite masses and quantities of accepted forage biomass (vegetation species used proportionately more than or equal to availability). Caribou achieved highest intakes at sites with an abundance of selected deciduous shrubs (e.g., willow-alpine sites, young forests) that afforded large bite masses, whereas lowest intakes occurred where mean bite masses were small (e.g., dry alpine, nutrient-poor forests). Dietary digestible energy (DE) and protein (DP) content, intake rates, and foraging time varied across plant communities and among nutritional classes. Caribou increased foraging time, but could not compensate for low intake rates and some plant communities failed to provide caribou with adequate nutrient intakes to support nutritional demands for lactation and maintenance of body mass. Although highest nutrient intakes were associated with productive sites, predation risk and disturbance may constrain the nutritional benefits caribou can acquire from these sites. In a pilot study, I mapped foodscapes of DE and DP intakes for a herd of free-ranging boreal caribou. Caribou did not select for nutrient intakes, but other factors including food quantity, predation risk, and accuracy of spatial data layers, may have confounded my ability to isolate the role of nutrition in habitat selection. Insights from this study into the nutritional ecology of caribou during summer can better inform caribou conservation and management.

Available in PDF, EPUB and Kindle. Book excerpt: The #1 selling wildlife management book for 40 years, now updated for the next generation of professionals and students. Since its original publication in 1960, The Wildlife Techniques Manual has remained the cornerstone text for the professional wildlife biologist. Now fully revised and updated, this eighth edition promises to be the most comprehensive resource on wildlife biology, conservation, and management for years to come. Superbly edited by Nova J. Silvy and published in association with The Wildlife Society, the 50 authoritative chapters included in this work provide a full synthesis of methods used in the field and laboratory. Chapter authors, all leading wildlife professionals, explain and critique traditional and new methodologies and offer thorough discussions of a wide range of relevant topics. To effectively incorporate the explosion of new information in the wildlife profession, this latest edition is logically organized into a 2-volume set: Volume 1 is devoted to research techniques and Volume 2 focuses on pragmatic management methodologies. Volume 1 describes research design and proper analytic methods prior to conducting research, as well as methods and considerations for capturing and handling wild animals and information on identification and marking of captured animals. It also includes new chapters on nutritional research and field sign identification, and on emerging topics, including structured decision-making. Finally, Volume 1 addresses measurements of wildlife abundance and habitat and research on individual animals. Volume 2 begins with a section on the relationship between research and management including public outreach, described in a context that encourages engagement prior to initiation of management. An adaptive management approach is described as a cornerstone of natural resource management, followed by a section on managing landscapes and wildlife populations. The volume also includes new chapters on ethics in wildlife science and conservation, conflict resolution and management, and land reclamation. A standard text in a variety of courses, the Techniques Manual, as it is commonly called, covers every aspect of modern wildlife management and provides practical information for applying the hundreds of methods described in its pages. This deft and thorough update ensures that The Wildlife Techniques Manual will remain an indispensable resource, one that professionals and students in wildlife biology, conservation, and management simply cannot do without.

Available in PDF, EPUB and Kindle. Book excerpt: In 1988, the British Columbia Ministry of Environment, Lands and Parks initiated the Mountain Caribou and Managed Forests program in response to forestry conflicts related to timber harvesting in the caribou's winter range. This report provides information from the radio-telemetry component of the program, 1988-91, designed to determine seasonal movements and habitat use patterns by mountain caribou (Rangifer tarandus caribou) east of Prince George, British Columbia. The data focus on seasonal habitat selection within the Engelmann spruce/subalpine fir biogeoclimatic zone, where mountain caribou spend the winter foraging on arboreal lichens. The results presented include the types of forest stands used by the caribou, when those sites were used, and seasonal use of slopes.

This book was released on 1993 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The West-Central BC Caribou Research Project was set up to investigate potential effects of logging on caribou in the Tweedsmuir-Entiako and Itcha-Ilgachuz-Rainbow areas. The original studies were expanded to include more intensive investigations of winter range and population parameters. The objectives of the project were to determine seasonal movements, habitat use and food habits of caribou in these areas, especially during winter so that logging guidelines compatible with caribou winter habitat use could be developed; and to determine population size, calf production, and calf and adult survival, so that current population status and limiting factors could be determined. This report summarizes results on caribou seasonal movements, habitat use and food habits. The report discusses methods for capture and marking, seasonal movements and habitat use, snow measurements, winter feeding ecology and fecal analyses. Results and discussion are also provided for these as well as for winter forest cover type use.

Available in PDF, EPUB and Kindle. Book excerpt: Temperate rainforests are biogeographically unique. Compared to their tropical counterparts, temperate rainforests are rarer and are found disproportionately along coastlines. Because most temperate rainforests are marked by the intersection of marine, terrestrial, and freshwater systems, these rich ecotones are among the most productive regions on Earth. Globally, temperate rainforests store vast amounts of carbon, provide habitat for scores of rare and endemic species with ancient affinities, and sustain complex food-web dynamics. In spite of their global significance, however, protection levels for these ecosystems are far too low to sustain temperate rainforests under a rapidly changing global climate and ever expanding human footprint. Therefore, a global synthesis is needed to provide the latest ecological science and call attention to the conservation needs of temperate and boreal rainforests. A concerted effort to internationalize the plight of the world’s temperate and boreal rainforests is underway around the globe; this book offers an essential (and heretofore missing) tool for that effort. DellaSala and his contributors tell a compelling story of the importance of temperate and boreal rainforests that includes some surprises (e.g., South Africa, Iran, Turkey, Japan, Russia). This volume provides a comprehensive reference from which to build a collective vision of their future.

This book was released on 2010 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woodland caribou (Rangifer tarandus caribou) are federally listed and declining across Canada because of the cumulative impacts of human infrastructure development. The Atlin northern mountain herd, in the territory of the Taku River Tlingit First Nation (TRTFN), British Columbia, is less affected by development than southern herds. However, recent low productivity in this herd suggests that the impacts of development (i.e., roads, mines, cabins and towns) may be accumulating. To predict the cumulative impact of human development on the Atlin herd, we developed seasonal resource selection functions (RSF) at 2 spatial scales with data from 10 global positioning system collared caribou. We modeled habitat selection and assessed cumulative effects by estimating the zone of influence (ZOI) around several types of human development. At the landscape and home range scale caribou avoided the ZOI and selected pine-lichen forests in winter and alpine habitats in summer. Approximately 8 and 2% of high quality habitat was lost due to avoidance of current development at the landscape scale in winter and summer, respectively. Future development of access roads to 2 mines would cause a further loss of 1% of high quality habitat. Negotiating the complex political dynamics that surround caribou conservation often requires new approaches to management and recovery planning. The incorporation of traditional ecological knowledge (TEK) with Western science could improve efficiency of management decisions and enhance the validity and robustness of ecological inferences. Therefore, we evaluated how well RSF and TEK habitat models predicted current woodland caribou observations and compared the spatial predictions of both modeling approaches. Habitat suitability index models were generated from TEK interviews with TRTFN members. Though comparison of habitat ranks between the 2 models showed spatial discrepancies in some cases, overall, both approaches had high model performance and successfully predicted caribou occurrence. Our results suggest TEK can be used to identify caribou habitat and is a useful approach in northern ecosystems that frequently lack long-term ecological data that are needed to inform management decisions. Combining TEK-based habitat suitability index models with cumulative effects assessments will facilitate recovery goals for woodland caribou across northern Canada.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Throughout the 1800s and the 1900s, woodland caribou (Rangifer tarandus caribou) disappeared from the upper Nechako lowlands of the interior of British Columbia, and herds in the surrounding mountain ranges contracted. Conversely, moose (Alces alces) populations expanded during the 1900s and rapidly colonized former caribou habitat. Using historical-ecological methods of research and Geographic Information System (GIS) software, I documented caribou and moose historical distribution and abundance, and examined the causative mechanisms that led to caribou decline. I gathered historical information from four sources: 1) secondary literature; 2) semi-structured interviews with aboriginal and non-aboriginal elders; 3) journals of the Hudson's Bay Company of Fort St. James; 4) other written primary sources. The findings of this study provide evidence of greater historical distribution and abundance of caribou, and confirm the value of Traditional Ecological Knowledge of First Nations (TEK) and of long-term historical perspectives for the study of ecological changes over time."--P. ii.

Book excerpt: Maintaining forest biodiversity by combining protection, management and restoration of forest and woodland landscapes is a central component of sustainable development. Evidence that there are threshold levels for how much habitat loss may be tolerated for viable populations of specialised species to be maintained. Policy-makers, businesses and managers pose questions about how to balance use of renewable forest resources and conserve biodiversity. Examples are presented on how biodiversity assessments can be made. Proposes how the critical gaps in our knowledge identified throughout the book could be filled through macroecological research and international co-operation.

This book was released on 2006-05-25 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.
