Understanding interactions between competition and climate in relation to their effects on individual tree growth is crucial the development of climate-sensitive models required for modelling boreal forest succession a changing climate. We used data from permanent yield sample plots western Canada Alaska investigate impact within regional gradient climatic conditions lodgepole pine (Pinus contorta Douglas ex Loudon), jack banksiana Lamb.), trembling aspen (Populus tremuloides Michx.), balsam...

Abstract In the face of anticipated climate change, growth models require modifications to effectively model likely future and survival trees stands. To support incorporation effects in Mixedwood Growth Model (MGM), we developed climate-sensitive mixed for lodgepole pine (Pinus contorta Douglas ex Loudon), jack banksiana Lamb.), trembling aspen (Populus tremuloides Michx.), balsam poplar balsamifera L.) white spruce (Picea glauca (Moench) Voss), examined how tree size, intra- interspecific...

Yield models are important for effective forest management and as such were developed the University of Benin Gmelina arborea plantation, Nigeria. The objectives study to develop, evaluate compare predictions from some non-linear timber volume estimation. A total nine comprising three each weibull, logistic log-normal using independent variables combinations (Basal area merchantable height, diameter at base middle height). assessment criteria (correlation coefficient (R), determination (R2),...
