Relative Impact of Aspen Competition and Soil Factors on the Performance of Lodgepole Pine and Hybrid White Spruce in North-central British Columbia
Author: C. DeLong
Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 26
Book Description
"Releasing conifers from the competition effects of aspen (Populus tremuloides Michx.) is a key focus of plantation management in sub-boreal and boreal forests, often at considerable cost. However, other factors affect early plantation performance. This study investigates the relative influence of aspen competition and soil factors on the performance of planted lodgepole pine (Pinus contorta Dougl. ex Loud.) and hybrid white spruce (Picea glauca [Moench] Voss x engelmannii Parry ex Engelm.) in north-central British Columbia. Plots were established across a gradient of natural aspen competition levels that resulted from a test of aspen control treatments at one site. Within these plots, 240 of each of the target conifer species were measured and their immediate soil and vegetative environment quantified. Regression trees and regression analysis were used to examine the importance of aspen competition relative to other factors in determining target conifer size."--Document.

Sustaining Forest Ecosystems
Author: Klaus von Gadow
Publisher: Springer Nature
ISBN: 3030587142
Category : Technology & Engineering
Languages : en
Pages : 429
Book Description
Forest ecosystems include a great variety of communities of organisms interacting with their physical environment: multi-aged natural forests, even-aged monocultures, and secondary forests invaded by foreign species. The challenge is to sustain their ability to function, by adapting to changing climates and satisfying a multitude of human demands. Our first chapter sets the scene with a discussion about the effects of forest management on ecosystem services. Details about forest observational infrastructures are introduced in the second chapter. The third chapter presents methods of analysing forest density and structure. Models for estimating the shape and growth of individual forest trees are introduced in chapter 4, models of forest community production in Chapter 5. Methods and examples of sustainable forest design are covered in chapter 6. New scientific contributions continue to emerge as we are writing, and this work is never finished. We hope to continue with regular updates replacing obsolete sections with new ones, but the general aim remains the same, to introduce a range of methods that will assist those interested in sustaining forest ecosystems.
