Growth and yield models for mixed Jack pine / black spruce stands by Gordon Donald Nigh Download PDF EPUB FB2

Growth and yield projections for monospecific and mixed stands of Scots pine and European beech were made by means of a previous model developed from a set of the Spanish National Forest Inventory.

Individual-tree distance independent diameter growth models were developed for black spruce and jack pine plantations. Data used in this study came via stem analysis on black spruce (Picea mariana [Mill.]B.S.P.) and jack pine (Pinus banksiana Lamb.) trees sampled from 75 stands of 25 even-aged monospecific plantations for each species in the Canadian boreal forest region of northern Cited by: Individual-tree models of five-year basal area growth were developed for jack pine (Pinus banksiana Lamb.) and black spruce (Picea mariana (Mill.) BSP) in northern Ontario.

Tree growth data were collected from long-term permanent plots of pure and mixed stands of the two species. The models were fitted using mixed model methods due to. The purpose of this study was to develop growth inter-cept models for black spruce, jack pine and balsam fir in r objective was to provide an interim valida-tion of the models based on an independent data gen-eral, the modelling technique closely follows that of Nigh (a), which should be consulted for additional details.

Individual-tree distance independent diameter growth models were developed for black spruce and jack pine plantations. Data used in this study came via stem analysis on black spruce (Picea.

Forest growth models are mathematical or computer models to project the future state and yields of forest stands or forest trees, over a time scale of from a few years to many decades.

Structure and function of growth models vary: some are purely empirical, based on the reproduction of past observations, while others explicitly mimic specific processes relative to tree ecophysiology, stand.

The growth intercept models pre-sented in this Extension Note are based on data collected by researchers at the University of British Columbia to study black spruce ecosystems and their productivity (Krestov et al.

Here we studied the growth of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) in mixed versus pure stands on 32 triplets located along a productivity gradient through Europe, reaching from Sweden to Bulgaria and from Spain to the Ukraine.

A follow-up of these estimates, using a different modelling approach, provided a new set of net C drawdown values for boreal afforestation sce-narios, ranging from 58 to 97 t C ha–1 (after 70 years) depending on whether larch, black spruce, or jack pine was the planted species (Boucher et al.

The objectives of this study were to develop a growth and yield model for yellow-poplar that can be used to evaluate thinning options.

This model should be efficient to use and provide detailed information about stand structure. To accomplish these objectives, we 1.

The observed patterns of radial variation in the mechanical properties of Scots pine in the current study (i.e., a rapid increase in the juvenile zone toward larger, more stable mature wood values) were similar to those reported in previous studies on Scots pine (Verkasalo and LebanAuty and Achim ), hybrid larch (Leban and Haines Cited by: 5.

This model allows the user to simulate stand dynamics of even-aged naturally regenerated longleaf pine forests under different management scenarios. Black spruce, Picea mariana (Mill.) B.S.P., in Alaska is largely overlooked in terms of growth and yield research because of its small size and slow growth.

Growth and yield information is therefore limited or nonexistent. This study developed the first polymorphic site index (height-age) curves and height-diameter functions for predicting height and volume for Alaska black.The height-increment models, as expressed in, provide individual tree height-increment predictions for white spruce and aspen grown in the boreal mixed-species stands in Alberta.
