Download or read book Mapping Forest Landscape Patterns written by Tarmo K. Remmel and published by Springer. This book was released on 2017-09-07 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the concepts, premises, advancements, and challenges in quantifying natural forest landscape patterns through mapping techniques. After several decades of development and use, these tools can now be examined for their foundations, intentions, scope, advancements, and limitations. When applied to natural forest landscapes, mapping techniques must address concepts such as stochasticity, heterogeneity, scale dependence, non-Euclidean geometry, continuity, non-linearity, and parsimony, as well as be explicit about the intended degree of abstraction and assumptions. These studies focus on quantifying natural (i.e., non-human engineered) forest landscape patterns, because those patterns are not planned, are relatively complex, and pose the greatest challenges in cartography, and landscape representation for further interpretation and analysis.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

This book was released on 1982 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1975-1976, pine trees killed by the southern pine beetle (Dendroctonus frontalis Zimm.) in a 2170-hectare (5362-acre) area at the William B. Umstead State Park in central North Carolina, were monitored by sequential color infrared aerial photography. From 1973 through summer 1975, beetles in 350 infestation spots killed more than 20,500 pines on 137 hectares (339 acres). From October 1975 to July 1976, an additional 301 dead pines were detected at 146 tree mortality centers. Southern pine beetles were associated with 98 percent of these dead trees. Pine mortality dropped rapidly from 248 trees killed in fall and winter at 120 spots to 9 trees killed in July at six spots. The volume of timber killed during the outbreak exceeded 16,000 m3 (7500 cords) of roundwood valued at more than $240,000. Strictly speaking, this is not an economic loss because the Park's management goal is to maintain a "natural forest."

This book was released on 2011 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2007, a multi-year connectivity modelling experiment was initiated to better understand the movement potential of mountain pine beetle (MPB) in Alberta and Saskatchewan pine forests. In the first year, spatial models of highly susceptible pine forest connectivity were developed for Alberta and Saskatchewan. The following year, the study focused solely on Alberta pine forests as our investigation turned to examine the effect that different pine species have on the connectivity model. In the third year (2009-10), the influence of climate on the landscape connectivity in Alberta was explored. To investigate the impacts of possible climate changes, minimum planar graphs were developed for the Alberta pine forests based on a modified stand susceptibility index. It was found that the stand susceptibility index most closely reflected observed MPB spread patterns when there were no climatic limitations in the model. A preliminary verification of the connectivity model was also performed. Using the model to determine expected 2009 MPB locations based on observed 2008 MPB source locations, both visual and statistical comparisons were performed to determine how well the model matched observed MPB spread. Generally, MPB were preferentially selecting closely connected habitat, but some of the direction of spread did not follow expected patterns. Some factor other than habitat connectivity (such as wind direction during MPB flight or topography) was influencing MPB spread: this warrants further exploration.
