Trees and Shrubs
Most of the trees found in Grand Teton National Park are cone-bearing otherwise known as conifers. Lodgepole pines inhabit areas that are periodically burned by forest fires. Their specially-designed serotinous cones open only when heated by fire causing them to drop a huge number of seeds on the newly sunlit and fertile post-fire soil. Whitebark and limber pines produce nuts that are an important food source for many birds, small mammals, and grizzly bears. Spruce-Fir forests consisting of blue spruce, Engelmann spruce, Douglas fir, and subalpine fir take over after other trees like lodgepole pine and quaking aspen have prepared and stabilized the soil.
Did You Know?
Did you know that the bark on Aspen trees looks green because it contains chlorophyll? Aspen bark is photosynthetic, a process that allows a plant to make energy from the sun, and helps the tree flourish during the short growing season.
