This book was released on 2002 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study represents an analysis of regeneration processes for eastern white pine (Pinus strohus L.). The objective is to develop an integrated approach to evaluate the influence of factors that, alone and in combination, determine regeneration outcomes. This study is composed of three sections. The first chapter is a literature review of white pine regeneration dynamics. The purpose is to present a process for understanding the regeneration process of a single species and present a conceptual approach to integrated evaluation of influential variables. Six interrelated ecological factors (seed tree density, competition, disturbance, seedbed conditions, soils, and damage agents) were identified and their impact on the regeneration process is evaluated. A conceptual model of the integration approach and two examples of how this approach can be utilized in assessing regeneration operations are presented.

This book was released on 1993 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plots were established to monitor the survival of immature lodgepole pine (Pinus contorta var. latifolia Engelm.) in over 70 cutover areas in the subalpine and boreal forest regions of west-central Alberta. A method for rating site productivity, based on weights assigned to soil associations, drainage classes, and elevations was used to group the areas into three productivity classes. Three-year survival rates spanning a 9-year period are given for most of the sampling areas, grouped according to site productivity. The major causes of mortality were rodents, western gall rust (Endocronartium harknessii [J.P. Moore] Y. Hiratsuka), Armillaria root rot (Armillaria spp.), Warren rootcollar weevil (Hylobius warreni Wood), blister rust (Cronartium spp.), browsing, blowdown, as well as undetermined causes. Mammal damage of all types and pitch blister moth (Petrova albicapitana [Busck] and Petrova metallica [Busck]) infestations were considerably higher in thinned stands. Armillaria root rot and the Warren rootcollar weevil caused more damage to dense stands.
