Trees of Colorado The Ponderosa Pine
Hoss and Little Joe may have roamed the Ponderosa in Nevada, but the Ponderosa pine is right at home along Colorado’s Front Range. In fact, it’s the most widely distributed pine in North America, covering vast areas of the western US including 2 million acres in Colorado. The Nature Conservancy considers it one of the five most iconic trees of the state. It plays a vital role in Colorado’s drinking water supply, especially in the heavily populated areas of the Front Range. Its thick foliage and carpet of needles hold snow and moisture, tempering runoff and making the Ponderosa pine a high priority for conservation and forest management.
Don’t Neglect Storm Damage
The strong winds of early April left a lot of tree damage in their wake. Broken branches and fallen trees were common across the metro Denver area. Now that the worst of the damage has been cleared up it’s time to take a look at the aftereffects.
Walk around your property and look for leftover damage such as exposed wounds where branches were torn away and partial breaks that have weakened limbs. Check around root areas to see if there are signs of partial uprooting.
