White spruce is native to the northern temperate and boreal forests of North America. This conifer has a long, straight trunk with gray-brown bark, and a narrow, spirelike crown. The bluish-green needles are stiff and sharp-pointed and occur more densely on the upper sides of twigs. Trees typically don't begin producing seeds in quantity until they are 30 years old; seed crops may be plentiful every 2 to 6 years, but more often occur every 10 to 12 years. White spruce needles, bark and twigs may comprise an important component of the snowshoe hare's winter diet. Mice and voles feed on the saplings as well as the seeds of this tree.
