Pinus banksiana - Jack Pine
Abstract. Increased fire frequency, extent and severity are expected to strongly affect the structure and function of boreal forest ecosystems. In this study, we examined 213 plots in boreal forests dominated by black spruce (Picea mariana) or jack pine (Pinus banksiana) of the Northwest Territories, Canada, after an unprecedentedly large area burned in 2014. Plant Guide - USDA PLANTS defoliates mature jack pine. The jack pine budworm, native to North America, has a range that coincides almost exactly with jack pine, its preferred host.

The type shows little variation.
