This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newfoundland woodland caribou (Rangifer tarandus caribou) populations are in steep decline and disturbance-related habitat loss and fragmentation have been blamed for similar woodland caribou population declines across the country. Research has focused on caribou habitat selection, and there is a need for studies to focus on landscape components that can be managed, and their relationships with caribou vital rates. I quantified landscape composition and configuration within the calving/post-calving range (CPCR) of female woodland caribou belonging to six herds in Newfoundland to explore their influence on calf recruitment over four years. I identified the CPCR of radio-collared female caribou and calculated the total disturbance area (area of forest fires and area within 250m of human disturbance sources), area occupied by natural landcover types, and three fragmentation measures (effective mesh size, edge to area ratio, and fragmentation extent) for each female's CPCR, and averaging them yearly for each herd. Total disturbance area and the area occupied by mixed forests were found to have negative effects on calf recruitment, whereas no significant direct relationship was found between either of the fragmentation measures and calf recruitment. Using Information Theoretic Approach, I found that the most parsimonious model to explain variation in calf recruitment included total disturbance area, the area occupied by mixed forests and wetlands, and the edge to area ratio measure of fragmentation. The effect of total disturbance area was negative, while the effect of wetlands was positive. It appears that combining quantitative measures of disturbance-related landscape structure (i.e. composition as well as configuration) to explain variation in woodland caribou calf recruitment, or other vital rates, would improve our ability to relate scientific research findings to wildlife management and land-use issues.

Available in PDF, EPUB and Kindle. Book excerpt: We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our intended audience is field ecologists in general and, in particular, wildlife and fisheries biologists who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function (RSF), where this is a function of characteristics measured on resourceunits such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

Schindler and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada's boreal woodland caribou (Rangifer tarandus caribou Gmelin) are listed as "Threatened" under the Canadian Species at Risk Act (SARA) and provincially under the Manitoba Endangered Species Act (MESA). Two of three provincially designated high-risk boreal woodland caribou ranges occur in eastern Manitoba and have been studied using Global Positioning System (GPS) tracking technology. This project was undertaken with the cooperation of the Eastern Manitoba Woodland Caribou Advisory Committee (EMWCAC). I investigated the development of an objective criterion using an adaptive kernel analysis to define core areas of use and the sensory effects of all weather access. A Habitat Suitability Index (HSI) model for woodland caribou was evaluated to determine if woodland caribou were selecting high quality habitat as defined by the model. Habitat use and selection at course and fine scales was assessed to determine landscape and stand level selection and use. A case study of habitat use and selection using forest inventory attribute data was also conducted and a comparative analysis was undertaken to determine differences in habitat use and selection between two ecologically distinct caribou populations. The criteria used to define core areas yielded mapping outputs that could provide a surrogate for critical habitat and a basis for management zoning and habitat planning. Analysis of the animal use of high quality habitat as predicted by the HSI model illustrated that woodland caribou selection of high quality habitat versus its availability is significant. Course or landscape scale habitat selection and use analysis illustrated that woodland caribou require large tracts of jack pine dominated forest containing black spruce, treed rock and muskegs. At the fine or stand level scale, woodland caribou selected habitat based on discrete variables described in the forest inventory attribute data. Woodland caribou preferred 60 - 80 year old pine dominated forest with a crown closure greater than 50%, interspersed with black spruce, rock outcrop and treed muskegs. Woodland caribou habitat containing greater proportions of treed rock and muskeg in pine dominated forest was important to woodland caribou in eastern Manitoba. The effects of the Happy Lake Road on woodland caribou use and animal energetics are measurable. Woodland caribou illustrate avoidance at approximately 2 kilometres from the road with maximum use of habitat occurring at 9 kilometres from the road. The location of the Happy Lake Road may be favourable considering the location of the Black River. Avoidance of the Happy Lake Road by the Owl Lake animals may be a function of predator and human avoidance. General management implications from this study include the use of the objective criteria for adaptive kernel analysis to determine ecologically representative core use areas that can be used in integrated management zoning. It also has application as a tool for proactive monitoring in the determination of core areas and critical habitat in resource development and mitigation.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Slate Islands caribou (Rangifer tarandis caribou) is an insular population which has experienced several population crashes and has been described as likely to succumb to extirpation. While a great deal of research has been conducted on mainland woodland caribou, factors which influence caribou distributions may differ between island and main land populations. In this thesis, I investigate relationships between habitat, landscape, anthropogenic features, population size, predation and spatial distribution of woodland caribou across the Slate Islands Provincial Park (Ontario) at the forest-patch spatial scale. Generalized linear models were used to compare observed caribou locations to available locations across the park, based on data from 1978 to 1995. Results indicated that the Slate Islands caribou selected deciduous cover, larger forest patches, areas further to water, flatter areas, lower elevations and areas closer to anthropogenic features. Population size had a limited effect on caribou distributions.

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 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.

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.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To expand upon previous Department of Environment and Natural Resource (ENR) studies of habitat selection by boreal woodland caribou in the northern part of their Northwest Territories (NWT) range (Nagy et al. 2005, 2006), resource selection function (RSF) analysis was carried out with data from 58 boreal caribou that were fitted with satellite and GPS collars between 2002 and 2011 in the Sahtú, Gwichʼin and Inuvialuit Settlement Regions (ISR). Habitat selection by boreal caribou was evaluated at two spatial scales: the selection of home ranges within the study area (broad scale) and the selection for different areas within each caribou's home range (finer scale). Each scale of habitat selection was evaluated separately for the winter, calving, summer, and fall breeding seasons. To evaluate selection of home ranges within the study area, habitat features at random locations drawn within individual seasonal home ranges were contrasted to habitat features at random locations distributed throughout the study area. Habitat selection within home ranges was evaluated by comparing habitat features at each observed collar location to habitat features at random locations drawn from within individual seasonal home ranges. This approach allowed the two scales of habitat selection to be combined into RSF maps that captured both scales of habitat selection. Habitat features considered in the analysis included land cover type, vegetation productivity, slope, elevation, distance to lakes and rivers, density and distance to seismic lines, presence of roads, and presence of forest fires

Book excerpt: Forest fire is the primary natural disturbance process influencing the distribution and abundance of terrestrial lichens across ranges of woodland caribou (Rangifer tarandus caribou), including the Klaza Caribou Herd in west-central Yukon. I used stand and understory data to understand variation in the abundance of lichens in burns of various ages. Focusing on the distribution of individual caribou, I used a dataset of GPS collar locations to examine resource selection on the winter range and within burns. Results suggested that burns provided suboptimal habitat for the KCH until 50 years post-fire; however, analyses focused on the use of burned habitat indicated that they regularly encountered burns and opportunistically used remnant lichen within the burn perimeter. The relationship between caribou and burned landscapes is complex and non-linear indicating that wildlife managers should look beyond burn age to account for the effects of fire on the availability and quality of caribou habitat.
