Pinaceae -- Pine family

    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). It  grows farther north than any other American pine and is the most widely  distributed pine species in Canada. It is a pioneer species in succession  and invades areas where mineral soil has been exposed by major  disturbances such as fires. It usually grows in even-aged pure or mixed  stands on less fertile and drier soils than those required by other native  species in its range (38).
