Download or read book Expert Knowledge and Its Application in Landscape Ecology written by Ajith H. Perera and published by Springer Science & Business Media. This book was released on 2011-10-21 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Typically, landscape ecologists use empirical observations to conduct research and devise solutions for applied problems in conservation and management. In some instances, they rely on advice and input of experienced professionals in both developing and applying knowledge. Given the wealth of expert knowledge and the risks of its informal and implicit applications in landscape ecology, it is necessary to formally recognize and characterize expert knowledge and bring rigor to methods for its applications. In this context, the broad goal of this book is to introduce the concept of expert knowledge and examine its role in landscape ecological applications. We plan to do so in three steps: First we introduce the topic to landscape ecologists, explore salient characteristics of experts and expert knowledge, and describe methods used in capturing and formalizing that knowledge. Second, we present examples of research in landscape ecology from a variety of ecosystems and geographic locations that formally incorporate expert knowledge. These case studies address a range of topics that will interest landscape ecologists and other resource management and conservation professionals including the specific roles of expert knowledge in developing, testing, parameterizing, and applying models; estimating the uncertainty in expert knowledge; developing methods of formalizing and incorporating expert knowledge; and using expert knowledge as competing models and a source of alternate hypotheses. Third, we synthesize the state of knowledge on this topic and critically examine the advantages and disadvantages of incorporating expert knowledge in landscape ecological applications. The disciplinary subject areas we address are broad and cover much of the scope of contemporary landscape ecology, including broad-scale forest management and conservation, quantifying forest disturbances and succession, conservation of habitats for a range of avian and mammal species, vulnerability and conservation of marine ecosystems, and the spread and impacts of invasive plants. This text incorporates the collective experience and knowledge of over 35 researchers in landscape ecology representing a diverse range of disciplinary subject areas and geographic locations. Through this text, we will catalyze further thought and investigations on expert knowledge among the target readership of researchers, practitioners, and graduate students in landscape ecology.

Book excerpt: The last remaining woodland caribou (WC) pop. in the U.S. has inhabited the southern Selkirk Mountains (SSM), located in NE Wash., N Idaho, and SE Brit. Columbia (BC). By the early 1980s, this pop. had dwindled to about 30. In 1983, the SSM pop. of WC was granted emergency protection under the Endangered Species Act. Fed. and state agencies in the U.S. and in BC have participated in a coop. program to recover the WC. This report provides info. on: the amount and source of funds expended on the WC recovery program (RP); the results of the RP, incl. the outcome of efforts to augment the pop.; and the impact of the RP efforts on land use.

This book was released on 2005-01-01 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Recovery plans are a comprehensive compilation of goals, objectives, strategies and actions, both short- and long-term, required to maintain or restore the Threatened or Endangered species. These plans are provided by the recovery team as advice to the Minister responsible for fish and wildlife management (the Minister) and to all Albertans. ... This recovery plan identifies effective and feasible strategies and actions necessary to achieve woodland caribou recovery and removal from the list of provincially threatened species. The recovery plan goals are linked to the rationale for listing the species in Alberta, and focus on: 1) achieving self-sustaining woodland caribou herds; 2) maintaining the distribution of caribou in Alberta; and 3) ensuring habitat requirements are met for woodland caribou over the long-term throughout caribou ranges in the province."--Document.

Book excerpt: Forest succession can be viewed, from a tree-centric point of view, as the temporal pattern of changes in tree species composition that occur following a disturbance that destroyed the existing forest cover, and includes the initial re-establishment of the forest cover. Fire is one such natural disturbance in boreal forests. The broad goal of the work reported here was to explore the body of boreal forest succession knowledge, to elucidate its strengths, weaknesses, and gaps, and to quantify its levels of uncertainty.--Document.
Download or read book Assessing Cumulative Human Impacts on Northern Woodland Caribou with Traditional Ecological Knowledge and Resource Selection Functions written by Jean Lieppert Polfus and published by . 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.
Download or read book Seasonal Movements Habitat Use and Winter Feeding Ecology of Woodland Caribou in West central British Columbia written by Deborah Bernadette Cichowski and published by . 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.

Ministry of Forests, Forestry Division Services Branch, Production Resources. This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a project that intended to determine the relative importance of the Chelaslie River study area to caribou (Rangifer tarandus), to determine whether habitats exist in the area which are preferentially used by the caribou, and to provide habitat management recommendations. The 87,000-hectare study area is located south of Ootsa Lake and north of Tetachuck Lake, east of Tweedsmuir Provincial Park in British Columbia. The area was selected to be larger than a previously defined caribou migration corridor in order to incorporate all observed locations of caribou, which were monitored by radio tracking from spring 1993 to spring 1995. Results presented include degree of use of the migration corridor, and habitat selection by season and within subzones of the area.
