Distinguishing the Pines Willows: Narrowleaf, Scouler's, Bebb and others not native to Colorado, such as the Whitebark pine and Black cottonwood in Yellowstone National Park, the Leaves: Oblong, 5 to 7 lobes with deep sinuses. Engelmann Spruce White Fir The Junipers Colorado Junipers: Rocky Mountain, One-seed, and Utah, The Spruces Uncommon Colorado natives coming from adjacent states For Colorado trees, I think the material presented here is still quite useful. Habitat: Grows on rocky soils in the foothills and on the plains; often associated with piñon pines. Green in development; tan when ripe. Bark: Green-white, smooth and thin with raised dark patches; on very large trees, trunk base is often gray, thick and furrowed. The Junipers and much of Wyoming including Grand Teton and Yellowstone National Parks. often grow as large shrubs - low diversity for such a large forested region, some 25,000 square miles, with many There are only some fifty kinds of trees native to all of Colorado, or even less if you do not count those which Botanical names are frequently revised and no attempt has been to to follow changes; the genus and species names are Habitat: High, cold forest environments on moist, northern slopes; with subalpine fir and other conifers. Colorado’s major tree species include bristlecone pine, Colorado blue spruce, Douglas-fir, Engelmann spruce, limber pine, lodgepole pine, narrowleaf cottonwood, quaking aspen, piñon pine, plains cottonwood, ponderosa pine, Rocky Mountain juniper, subalpine fir and white fir. White Fir Distinguishing the Spruces Where are you – there are no birch trees growing naturally in the lower Rocky Mountains. than for the same trees from other regions with different sizes and appearance. Dark green, palmately lobed; veined with 3 to 5 lobes. Trees were essential in the White Fir Bark: Gray, smooth and thin when young; red-brown, rough and furrowed into scaly ridges at maturity. May survive low severity fire; Top-killed by more severe fires, but may resprout. I also describe something about the trees' habits and the role of the trees in the forests of Colorado. Subalpine Fir Leaves: Broad-leaf foliage is shiny green with a pale underside; narrow and 2 to 3 inches long; lance shaped with a fine, serrated edge and a pointed tip. Fruit: Cones are yellow-brown, unique, short and squatty; 1 to 2 inches long. the surrounding foothills, shrublands, plains, and deserts. Leaves: Lance-shaped, 2 to 4 inches; light green turning bright yellow in autumn. than for the same trees from other regions with different sizes and appearance. Subalpine Fir The forest populations in Relation to Fire: Generally killed by fire due to thin bark, shallow roots, low growing branches, tendency to grow in dense stands and support heavy lichen growth.
