Jack pine
Plant - Pinus banksiana
Jack pine, also known as grey or scrub pine, is a species of North American pine. It ranges from 9-22 metres in height. Some jack pines are shrub-sized, due to poor growing conditions. Although it varies among populations, jack pine trees do not usually grow particularly straight, resulting in an irregular shape similar to that of pitch pine. This pine often forms pure stands on sandy or rocky soil. Many populations are adapted to stand-replacing fires, with the cones remaining closed for many years, until a forest fire kills the mature trees and opens the cones, reseeding the burnt ground.
