    We tested the hypotheses that responses to the mountain pine beetle fungal associate Grosmannia clavigera will differ between the evolutionarily co‐evolved host lodgepole pine (Pinus contorta var. latifolia) and the naïve host jack pine (Pinus banksiana) and that these responses will be influenced by water availability.G. clavigera inoculation resulted in more rapid stem lesion development.

As conditions have warmed, D. ponderosae has expanded to higher latitudes (9 – 11) and breached the geophysical barrier of the Canadian Rocky Mountains. It has now colonized the hybrid crossings of P. contorta and jack pine, Pinus banksiana Lamb., and also the pure P. banksiana .

    Introduction. Temperate and boreal forest ecosystems of western Canada provide more than 60% of Canada's harvest volume, with lodgepole pine (Pinus contorta Dougl. ex Loud.) and interior spruce (Picea glauca [Moench] Voss, P. engelmannii Parry ex Engelm. and their hybrids) being the most important forestry species (Canadian Forest Service ).Climate change threatens these . It has now colonized the hybrid crossings of P. contorta and jack pine, Pinus banksiana Lamb., and also the pure P. banksiana trees in this region (13, 14). These trees are contiguous with P. banksiana forests throughout all of southern Canada east of the Rocky Mountains, connecting with eastern white pine, Pinus strobus L., and red pine.

[G E Rehfeldt; James E Lotan; Intermountain Forest and Range Experiment Station (Ogden, Utah)]. X jack pine (Pinus banksiana Lamb.) were tested to determine whether adaptation and performance in Montana and Idaho justified improvement of lodgepole pine by hybridization.

Average heights, diameters, and survival rates of hybrids, of jack pines native to the Lake States, and of lodgepole pines native to Montana and Idaho were similar after.

Mature jack pine are usually 55 to 65 feet ( m) tall and 8 to 10 inches ( cm) in d.b.h. but can attain a maximum height of feet (30 m) and a diameter of 25 inches (64 cm) [].On extremely harsh, sandy sites, jack pine is small. Taken together, Pinus contorta is one of the most widely distributed pines in the western hemisphere, extending from Alaska south to Mexico and east through the Rocky Mountains to South Dakota.

Pinus contorta can be distinguished from its near relative P. banksiana by its seed cones, which are curved forward on branches, unarmed or with small reflexed apiculi. In P. banksiana the seed cones are spreading to recurved on branches, mostly armed with prickles ().

Jack pine (Pinus banksiana), also called scrub pine, Banksian pine, or Hudson Bay pine, is a small-to medium-sized coniferous tree of the northern forests of the United States and Canada, where it is an important source of pulpwood, lumber, and round timber (1,10,15,16).

Pinus resinosa: needle-like leaves mostly cm long, not or only slightly twisted and seed cones relativley symmetrical (vs. banksiana, with needle like leaves mostly cm long, twisted, and seed cones asymmetrical, curved and/or more developed on one side).

Shore pine is one of four varieties of lodgepole pine. The other three varieties are [9,24]: Rocky Mountain lodgepole pine (Pinus contorta var. latifolia), Sierra lodgepole pine (Pinus contorta var. murrayana), Mendocino White Plains lodgepole pine (Pinus contorta var. bolanderi). This write-up will focus on shore pine.

Pinus contorta, with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America.

It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines (member species of the genus Pinus), it is an evergreen conifer.
