Individual-tree diameter growth model for black spruce and ... 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 1170 black spruce (Picea ... Regeneration of black spruce (Picea mariana) and jack pine ... Age structure analysis was performed in black spruce (Picea mariana (Mill.) B.S.P.) and jack pine (Pinus banksiana Lamb.) stands following fire (i) to determine if there is a time lag between black spruce and jack pine establishment and (ii) to compare the composition of the regeneration with regard to the original stand. The study was conducted in an area burnt in 1983, 100 Black Spruce - Southern Research

In the limited area from which this type is known in Maine, most of the jack pine forest has been clearcut within the last 25 years and is now growing back as young jack pine forest. In areas where mature jack pine has not been cut, regeneration is primarily red or black spruce. Picea mariana - Wikipedia Picea mariana, the black spruce, is a North American species of spruce tree in the pine family. It is widespread across Canada, found in all 10 provinces and all 3 Arctic territories. Its range extends into northern parts of the United States: in Alaska, the Great Lakes region, and the upper Northeast.

The postfire regeneration dynamics of black spruce and jack pine were documented by a study of three successive cohorts (woody debris, snags, seedlings) within a large area burnt in 1989. The objectives of this study were (i) to describe how fire interval can influence the abundance of regenerating ... Black spruce and jack pine dynamics simulated under ... The postfire regeneration dynamics of black spruce and jack pine were documented by a study of three successive cohorts (woody debris, snags, seedlings) within a large area burnt in 1989. The objectives of this study were (i) to describe how fire interval can influence the abundance of regenerating black spruce and jack pine and (ii) to model the future abundance trends of these two species ... Jack pine - Natural Resources Canada Grows in pure stands or mixed with other shade-intolerant species such as white birch, trembling aspen, balsam poplar, red pine, and tamarack Shade-tolerant species such as black spruce, white spruce, and balsam fir often form the understory Climate‐diameter growth relationships of black spruce and ... B.S.P.) trees in boreal Ontario, we modified an existing diameter growth model to include climate variables. Diameter chronologies of 927 jack pine and 1173 black spruce trees, growing in the area from 47°N to 50°N and 80°W to 92°W, were used to develop diameter growth models in a nonlinear mixed‐effects approach.

Plant Life - Taiga The Jack Pine is a tree that is abundant across much of canada from the eastern side of the Rocky Mountains to Nova-Scotia. This tree rarely grows straight. This pine has waxy needles and rough bark that protect it from dehydration caused by cold winds. These features also protect it from forest fires that are common in the taiga.
