The Michigan Department of Natural Resources is applying herbicide treatments at six sites in the eastern Upper Peninsula this week in preparation for red and jack pine
For example, American Linden (Tilia americana), Douglas fir (Pseudotsuga menziesii), balsam fir (Abies balsamea), Eastern hemlock (Tsuga canadesis), Norway spruce (Picea abies), paper birch (Betula papyrifera), Jack pine
(Pinus banksiana) and white pine (Pinus strobus) are all considered highly vulnerable to the coming changes.
For nearly 30 years, American Forests has been restoring the Michigan jack pine
forests the Kirtland's warbler depends on for habitat.
The company said the assets are stocked with primarily red pine, jack pine
and hardwood forest types, which will supply a diverse customer base that manufacture utility poles, lumber, studs and pulp and paper products.
Coniferous species include red pine, white pine (Pinus strobus), jack pine
(Pinus banksiana), and eastern hemlock (Tsuga canadensis).
Often referred to as the "jack pine
warbler," the bird depends on breeding habitat that consists of large stands of dense, young jack pine

Eight-foot (2.4-m) 2 by 6-inch (38 by 140-mm) kiln-dried lumber was obtained of three species: jack pine

(1916-17), place him firmly in the wilderness among its pristine lakes and grand, beautiful trees.
Expanses of jack pine
(Pinus banksiana) and, in places, red pine (Finns resinosa) could be found on dry sandy ridges and uplands.
After the treatments the harvest sites were replanted with black spruce and jack pine
seedlings, said Hazlett.
Even as the mountain pine beetles run out of lodgepole pines to devour in the United States, in 2011 the insects made their first jump into a new species of tree, the jack pine
, in Alberta.
