This book was released on 2007-01-01 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every five years, the Fish and Wildlife Division of Alberta Sustainable Resource Development reviews the general status of wildlife species in Alberta. These overviews assign individual species "ranks" that reflect the perceived level of risk to populations that occur in the province. This document presents the Division's report concerning the status of the whitebark pine. Information is provided regarding the following aspects of the species: habitat, conservation biology, distribution, population size and trends, limiting factors, and status designations.--Includes text from document.

Available in PDF, EPUB and Kindle. Book excerpt: Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the regeneration stage of any species is key to determining the processes that lead to population persistence and structure, community development, and succession. In the case of the endangered whitebark pine (Pinus albicaulis), knowledge of regeneration processes will be important for developing approaches for recovery and restoration of the species. I investigated biophysical drivers of whitebark pine seedling presence, abundance, and growth in the northern Alberta Rocky Mountains where mortality from white pine blister rust (caused by the fungus Cronartium ribicola) and mountain pine beetle (Dendroctonus ponderosae) remains low and whitebark pine regeneration is poorly studied. Transects were established in different mesohabitats (community type and elevation) to determine how these factors influence whitebark pine regeneration. Mesohabitat-scale conditions and seedling density along each transect were measured and microsites with and without whitebark pine seedlings were characterized along each transect. The height, age and health of each whitebark pine seedling found in each microsite was recorded and a subset of seedlings was destructively sampled in order to analyze annual growth and release. In forest mesohabitats canopy gaps at microsite scales favored occurrence, growth rate and growth release. However, at the mesohabitat scale seedling abundance was positively related to canopy cover. Whitebark pine seedlings in open habitats below treeline were negatively associated with cover of rock, graminoids and seedlings of other tree species, grew fastest at intermediate values of temperature and dryness, and exhibited release in microsites with little other understory cover. These results suggest that at the northern portion of its range, whitebark pine grows best in conditions that limit competitors but still allow for sufficient growth. This contrasted with the situation in alpine and treeline mesohabitats, where increased growth rates, growth release and seedling presence were associated with warmer microsites that had higher vegetation cover. Seedling density in both open and treeline environments was highest along southwest facing slopes. That release and general success of seedlings was better in canopy gaps supports the use of restoration activities such as thinning overstory trees and planting in open mesohabitats or microsites. As the regeneration niche of whitebark pine differed among mesohabitats and biophysical drivers of success differed among presence, abundance and growth of whitebark pine, I suggest that it is critically important to consider the mesohabitat and all factors of regeneration success when restoring whitebark pine.

Available in PDF, EPUB and Kindle. Book excerpt: Whitebark pine (Pinus albicaulis Engelm.), an important component of western high-elevation forests, has been declining in both the United States and Canada from the combined effects of the exotic disease white pine blister rust (caused by the pathogen Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae) outbreaks, altered fire regimes, and climate change. These combined threats have led to the recent listing of whitebark pine as a high priority Candidate Species under the Endangered Species Act.
