Forest Service and Michigan Department of Natural Resources developed a habitat program that would manage jack pine
stands on a 50-year rotation.
Reference-specific gravities for each species (jack pine
420 kg/[m.sup.3], white spruce 350 kg/[m.sup.3], and Pacific silver fir 340 kg/[m.sup.3]) were used to convert results from weight per weight CuO to give weight per volume (kilograms per cubic meter) of the formulation assuming a 2:1 CuO/quat ratio.
also grew on soils with intermediate moisture where it was joined by white spruce (Picea glauca), balsam fir (Abies balsamea), and white birch (Betula papyrifera).
The bay was completely developed now, with a shopping list of water toys and accessories secured for the season, replacing the jack pine

Fire-dependent ecosystems, like prairies or jack pine

The beetles have also breached the historic geological barrier of the Northern Rockies and have moved halfway across Alberta where they now are infesting jack pine

Coatings were applied to heat-treated jack pine
The camera follows Sophie through a year as she harvests plants, taps balsam tree sap, cuts the edible inner bark from a Jack pine
that can save a lost hunter's life, and boils up raspberry branches on her stove for medicine.
AS SEEN HERE among the charred trunks of black spruce (Piceamariana) and jack pine
(Pinus banksiana), the resilient fireweed (Epilobium angustifolium) lives up to its reputation.
of New Brunswick, Canada) covers the 12 most common species indigenous to North America (balsam fir, eastern hemlock, tamarack larch, eastern white pine, jack pine
, pitch pine, red pine, black spruce, red spruce, white spruce, eastern juniper, and eastern thuja), follows the life cycle of the tree, from seed to sapling, and compares genera and species at each stage.
The Kirtland's Warbler, North America's rarest songbird, has one of the most limited ranges of any landbird on the continent and breeds almost exclusively in Michigan, though some breeding occurs in Wisconsin and Ontario, in early succession jack pine
(Pinus banksiana) stands.
Vancouver opera has commissioned a children's opera, Jack Pine
, with music and libretto by composer Veda Hille.

? He's gnarled but he's got a tender side for he is also a "nurse tree" that shelters the seedlings of other trees.
