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: Silvicultural cutting treatments may be needed to restore whitebark pine (Pinus albicaulis) forests, but little is known of the response of this species to removal of competition through prescribed burning or silvicultural cuttings. We analyzed stem cross-sections from 48 whitebark pine trees in Montana around which most of the competing vegetation was removed by timber harvest treatments. We compared tree ring growth rates before and after the harvest treatment using intervention analysis to determine 1) the potential of release for this little-studied tree species and 2) whether the release is related to tree and stand characteristics. We defined release as a statistically significant increase in radial growth after competing trees were removed. All but one of our 48 sampled trees increased in diameter growth after competition was removed, while 40 trees showed a statistically significant (p

This book was released on 2015 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whitebark pine (Pinus albicaulis) populations are in decline across the species? range due to historic wildfire exclusion, mountain pine beetle (Dendroctonus ponderosae, MPB) outbreaks, and an invasive fungal pathogen causing the disease white pine blister rust (Cronartium ribicola, WPBR). Despite reliance on stand-replacing fires, information on whitebark pine regeneration occurrence is limited and the trajectory of future forests is largely unknown in some areas of the range. Regeneration densities were assessed in burned and adjacent non-burned areas at six high elevation locations in northwest Wyoming where stand-replacing fires occurred 8?32 years before the surveys. In these locations at the eastern extent of the species range, we assessed what site factors were associated with regeneration success. Whitebark pine regeneration density was greater and seedlings were older in non-burned compared to burned areas. Within burns, north aspects had more regeneration than south aspects. Potential seed source densities and other species? regeneration were positively related to whitebark pine regeneration densities in burned areas. South facing slopes or grass covered areas may have either delayed or no regeneration of whitebark pine without the help of artificial planting.

This book was released on 2012-10-19 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whitebark pine (Pinus albicaulis) forests are declining across most of their range in North America because of the combined effects of mountain pine beetle (Dendroctonus ponderosae) outbreaks, fire exclusion policies, and the exotic pathogen Cronartium ribicola, which infects five-needle white pines and causes the disease white pine blister rust. The loss of this high-elevation tree species poses serious consequences for upper subalpine ecosystems, both in terms of impacts on biodiversity and losses in ecosystem processes; whitebark pine is now a candidate species for listing under the Endangered Species Act. Large, nutritious seeds produced by whitebark pine are an important food for many bird and small mammal species, as well as grizzly (Ursus arctos horribilis) and black bears (Ursus americanus), and whitebark pine communities provide habitat for many additional wildlife species. Whitebark pine seed dispersal by Clark's nutcrackers (Nucifraga columbiana) combined with hardy seedlings results in early whitebark pine community development after fire and other disturbances; whitebark pine seedlings survive on harsh, arid sites and may act as nurse trees to less hardy conifers and vegetation. Whitebark pine at higher elevations, where it is common in many regions, helps regulate snow melt and reduce soil erosion. For these collective functions, whitebark pine is considered both a keystone species for promoting community diversity and a foundation species for promoting community stability. Since more than 90 percent of whitebark pine forests exist on public land in the United States and Canada, it is important that government natural resource management agencies play an important role in ensuring future presence of this tree species by initiating concerted, coordinated, and comprehensive restoration efforts. This is best accomplished through a coordinated, trans-boundary restoration strategy that includes shared infrastructure and expertise for conserving seeds, growing blister rust-resistant seedlings, protecting trees, restoring ecosystem processes, and promoting natural regeneration. We detail a multi-scale strategy for restoring whitebark pine across its range in the western United States and Canada. The strategy was compiled by researchers, land managers, and resource specialists for use as a reference for prioritizing, designing, and implementing successful whitebark pine restoration activities across many scales from stands to landscapes to its entire range. The whitebark pine restoration strategy consists of the following principles: (1) promote rust resistance, (2) conserve genetic diversity, (3) save seed sources, and (4) employ restoration treatments. These guiding principles are then used to implement the whitebark pine restoration strategy using a set of possible actions: 1. assess condition, 2. plan activities, 3. reduce pest impacts, 4. gather seed, 5. grow seedlings, 6. protect seed sources, 7. implement restoration treatments, 8. plant burned areas, 9. support research, and 10. monitor activities. The strategy is also organized by six spatial scales of analysis and organization: 1. range-wide, 2. region (National Forest Region or Provincial Regions), 3. forest (National Forest, National Park, and Canadian Forest District), 4. landscape (watershed or landform), 5. stand, and 6. tree. At each scale, we present four important factors in the restoration strategy: (1) assessment, (2) restoration actions, (3) management concerns, and (4) an example. Strategic restoration plans are presented for the coarse-scale strategies, while illustrated examples are presented for the finer scales (tree, stand, and landscape).

Download or read book Whitebark Pine Stand Condition Tree Abundance and Cone Production as Predictors of Visitation by Clark s Nutcracker written by Lauren E. Barringer and published by . This book was released on 2012 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: Accurately quantifying key interactions between species is important for developing effective recovery strategies for threatened and endangered species. Whitebark pine (Pinus albicaulis), a candidate species for listing under the Endangered Species Act, depends on Clark's nutcracker (Nucifraga columbiana) for seed dispersal. As whitebark pine succumbs to exotic disease and mountain pine beetles (Dendroctonus ponderosae), cone production declines, and nutcrackers visit stands less frequently, reducing the probability of seed dispersal. METHODOLOGY/PRINCIPAL FINDINGS: We quantified whitebark pine forest structure, health metrics, and the frequency of nutcracker occurrence in national parks within the Northern and Central Rocky Mountains in 2008 and 2009. Forest health characteristics varied between the two regions, with the northern region in overall poorer health. Using these data, we show that a previously published model consistently under-predicts the proportion of survey hours resulting in nutcracker observations at all cone density levels. We present a new statistical model of the relationship between whitebark pine cone production and the probability of Clark's nutcracker occurrence based on combining data from this study and the previous study. CONCLUSIONS/SIGNIFICANCE: Our model clarified earlier findings and suggested a lower cone production threshold value for predicting likely visitation by nutcrackers: Although nutcrackers do visit whitebark pine stands with few cones, the probability of visitation increases with increased cone production. We use information theoretics to show that beta regression is a more appropriate statistical framework for modeling the relationship between cone density and proportion of survey time resulting in nutcracker observations. We illustrate how resource managers may apply this model in the process of prioritizing areas for whitebark pine restoration.

Available in PDF, EPUB and Kindle. Book excerpt: From majestic Redwoods to ancient Western Bristlecone Pines, California's trees have long inspired artists, poets, naturalists—and real estate developers. Verna Johnston's splendid book, illustrated with her superb color photographs and Carla Simmons's detailed black-and-white drawings, now offers an unparalleled view of the Golden State's world-renowned forests and woodlands. In clear, vivid prose, Johnston introduces each of the state's dominant forest types. She describes the unique characteristics of the trees and the interrelationships of the plants and animals living among them, and she analyzes how fire, flood, fungi, weather, soil, and humans have affected the forest ecology. The world of forest and woodland animals comes alive in these pages—the mating games, predation patterns, communal life, and the microscopic environment of invertebrates and fungi are all here. Johnston also presents a sobering view of the environmental hazards that threaten the state's trees: acid snow, ozone, blister rust, over-logging. Noting the interconnectedness of the diverse life forms within tree regions, she suggests possible answers to the problems currently plaguing these areas. Enriched by the observations of early naturalists and Johnston's many years of fieldwork, this is a book that will be welcomed by all who care about California's treasured forests and woodlands.
