Ponderosa pines, spruce may exhibit ‘winter burn’ by Colo State Forest Service

A cold snap in October, coupled with last week’s extreme temperature fluctuations, injured ponderosa pines, other pine species and spruce trees in the Douglas and Elbert county areas, including Castle Rock, Franktown, Parker, Elizabeth and Kiowa. With warm weather preceding winter last year, the trees did not have the chance to transition into dormancy before freezing occurred. Large shifts in outside temperatures last week exacerbated the damage.
