DOWNLOAD EBOOK →Tables are presented for second growth stands of coastal Douglas-fir, some regenerated naturally and others planted at various densities. Separate tables describe the developments of stands thinned to 500 or 1110 stems when 6 metres tall.

DOWNLOAD EBOOK →Density manipulation is one of the most powerful tools available to silviculturists to achieve a broad range of silvicultural objectives. One of the most effective methods of planning density management in even-aged stands is through the use of stand density management diagrams. These diagrams graphically depict the temporal relationships between stand density, top height, quadratic mean diameter and mean tree volume. They allow the user to develop and project crop plans through time, to determine the optimum timing of thinnings, to determine the operational feasibility of thinnings, and to contrast potential outcomes from a number of stand management regimes. The stand density management diagrams for lodgepole pine, white spruce and interior Douglas-fir in this report were derived from managed stand yield tables produced by TASS, an individual tree, distance-dependent growth model. The report describes their use in planning thinning regimes and making preliminary yield estimations.

DOWNLOAD EBOOK →Forest Growth and Yield Modeling synthesizes current scientific literature and provides insights in how models are constructed. Giving suggestions for future developments, and outlining keys for successful implementation of models the book provides a thorough and up-to-date, single source reference for students, researchers and practitioners requiring a current digest of research and methods in the field. The book describes current modelling approaches for predicting forest growth and yield and explores the components that comprise the various modelling approaches. It provides the reader with the tools for evaluating and calibrating growth and yield models and outlines the steps necessary for developing a forest growth and yield model. Single source reference providing an evaluation and synthesis of current scientific literature Detailed descriptions of example models Covers statistical techniques used in forest model construction Accessible, reader-friendly style

DOWNLOAD EBOOK →Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.
