Common Trees in Colorado

Blue Spruce
Colorado's state tree, stiff blue needles - but needle cast disease is epidemic

Riparian species, fast-growing, brilliant yellow fall color
Active Tree Threats in Colorado
Mountain Pine Beetle critical
Affects: Lodgepole pine (primary), ponderosa pine, limber pine, whitebark pine
Native bark beetle whose populations have exploded due to drought and warmer winters that no longer kill overwintering larvae. Beetles mass-attack trees, introducing blue-stain fungi that stop water t...
Emerald Ash Borer critical
Affects: All ash species - very common urban trees in Front Range CO and Wasatch Front UT
Same devastating beetle as eastern US. Colorado and Utah cities planted heavily in ash - many municipalities have 15-20% ash canopy that will be lost.
Ips Beetle Complex moderate-high
Affects: Spruce, pine - urban and forest settings
Multiple Ips bark beetle species that attack weakened conifers. Unlike mountain pine beetle, Ips can have multiple generations per year and attacks a broader range of species including spruce.
When to Prune in Colorado
Late winter (February-March) for most. Avoid fall pruning - doesn't heal before winter
