This book was released on 2011 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of hectares of red pine (Pinus resinosa Ait.) plantations were established during the early 20th century to restore abandoned agricultural lands and increase forest cover. Concern over the ecological integrity [i.e. the degree to which a community is determined to be characteristic of its natural region, including abiotic and biotic components, likely to persist and maintain the rates of change and supporting processes (Canada National Parks Act (S.C. 2000, c. 32) 2011) of these plantations and a desire to increase native forest cover has prompted a more thorough understanding of the understory succession of these plantations. This study addresses the question, how does the understory vegetation composition and diversity in managed red pine plantations compare to the understory of a reference deciduous forest?. I examined the understory diversity in a chronosequence of managed red pine plantations owned by Simcoe County. Biophysical characteristics including diffuse non-interceptance (DIFN), tree regeneration, litter depth, and soil physical and chemical properties were gathered from three replicates of each of four age groups and from a reference deciduous forest group in order to determine how each variable changed and influenced the succession of the understory diversity. Field investigations were completed during the spring, summer, and fall of 2009 in order to examine seasonal differences in diversity. A two-way analysis of variance with a Tukey's post hoc test was used to determine if the forest groups were significantly different from each other for each variable measured. Species diversity (measured by the Shannon-Wiener Index) generally increased with plantation age and seasonal differences were apparent. A lack of significant difference between the oldest plantation group (est. 1927-1932) and the reference forest group indicates diversity is increasing; this is intriguing because, in contrast, species composition is only 30% similar. This may indicate either not enough time has passed for the understory to regenerate or the understory in the plantations is succeeding in a different trajectory. Furthermore, spring ephemeral species were lacking in the understory of the plantation forests indicating this phenological group is not regenerating in the plantations. Tree density is generally increasing in the plantation groups and the dominant tree species regenerating in the oldest plantation group includes a similar suite of species to that found in the reference forest groups. This indicates that the canopy is succeeding towards a native forest community. Pearson correlation analysis revealed that litter depth is significantly negatively correlated to diversity in the summer and fall (p

Book excerpt: This report reviews the literature relating to red pine and eastern white pine succession in the Great Lakes-St. Lawrence Forest from establishment to age 50. Research areas included red and white pine autecology, early red and white pine establishment and survival, post-disturbance natural successional patterns, and the effect of past and current management practices on early red and white pine survival and establishment. Professional foresters, working in Ontario, were consulted to determine current forest management practices.

Available in PDF, EPUB and Kindle. Book excerpt: "This bibliography includes a list and descriptions of the content of publications written or co-authored by staff of the Ontario Ministry of Natural Resources' Ontario Forest Research Institute between 2006 and 2010. During this five-year period, over 150 publications were produced by the institute's 14 research scientists, including a book, 83 journal articles, 31 reports, 10 technical notes, 5 newsletters, and 11 papers/summaries in conference/ workshop proceedings. The overall focus of the publications is forest resource management-related research and practice. Topical areas and scales of investigation are diverse and include natural disturbance regimes and landscape dynamics; carbon budgets and effects of climate change on forests; and silviculture studies on site preparation, tree improvement, vegetation management, growth and yield, disease management, and harvesting in conifer, mixedwood, and hardwood forests. Author and subject indexes are provided."--Document.

Available in PDF, EPUB and Kindle. Book excerpt: Classical silviculture has often emphasized timber models, fundamentally based in production agriculture. This books presents silvicultural methods based in natural forest models—models that emulate natural disturbances and development processes, sustain biological legacies, and allow time to take its course in shaping stands. These methods, dubbed “ecological forestry,” have been successfully implemented by foresters for decades managing a wide variety of forestlands. Ecological silvicultural strategies protect threatened and rare species, sustain biological diversity, and provide habitat for game and non-game species, all while providing timber in profitable ways.
