JACK PINE

PINUS BANKSIANA

 

Where does it come from ?

Jack pine is the most common species in the boreal zone. We found jack pine mostly in Abitibi, in the north part of the Mauricie and in Saguenay-Lac-St-Jean. Jack pine represents an annual volume of roundwood to transform more than 2.5 millions of m³. Its gnarled wood contains less resin than other species. With a low drying shrinkage, it has good dimensional stability when well dried. The heart of Jack Pine is known to have low permeability and even resistant to impregnation.

How is it used by the wood industry ?

This tree of 10 to 20 meters high is quite variable shape. Its pointed and slightly bent needles are 2 to 5 cm long. With pale yellowish green color, they are grouped by two and divergent. The color of the rind ranges from reddish brown to gray, then it becomes dark brown, scaly and sharp irregular grooves. It is commonly used to make posts, poles, fences, gates, moldings, floors, stairs, laminated glued panels, doors and windows, shelves, racks, furnitures. Jack Pine wood can be treated at high temperature.

How was it used traditionally ?

Several species of the boreal forest were used for their anti-inflammatory properties by the indigenous peoples of North America and Pinus banksiana is one of them. Boiled cones were used to make an anti-inflammatory balm, while the leaves were used in aromatherapy to treat patients in coma and to clean congested lungs. The gum was chewed to cure the common cold and its taste was considered excellent. A poultice for wound healing was made from inner bark previously crushed and boiled. This bark was also eaten as such. The oil and pine resins were used as disinfectants, antiseptics and insecticides. The infusion of bark was prescribed to treat breathing problems.
