225 active alerts in this region

TreeIssues monitors plant and tree health threats across Colorado. Below you will find current alerts for pests, diseases, fungi, and invasive species that have been detected in the state. Alerts are sourced from USDA, USFS, and Colorado state agricultural agencies. Each alert includes severity ratings, affected species, symptoms, and recommended treatments.

Mountain Pine Beetle

CRITICAL
Insect

A native bark beetle responsible for massive die-offs of lodgepole, ponderosa, and whitebark pines across western North America. Climate change has expanded its range northward and to higher elevations. Outbreaks have affected tens of millions of acres.

Affecting 9 regions

Dutch Elm Disease

CRITICAL
Disease

A devastating vascular wilt disease spread by elm bark beetles that has killed millions of American elms since the 1930s. The fungus blocks water-conducting vessels, causing rapid wilting. It fundamentally changed the American urban landscape.

Affecting 45 regions

Thousand Cankers Disease

HIGH
Disease

A disease complex involving the walnut twig beetle and an associated fungus that has caused significant mortality of black walnut, particularly in western states. Thousands of small cankers coalesce to girdle branches and the trunk.

Affecting 15 regions

Rhizosphaera Needlecast

HIGH
Fungus

A common fungal disease of spruce trees, especially Colorado blue spruce, throughout the Midwest and Northeast. The fungus infects current-year needles through stomata, causing them to turn purple-brown and drop prematurely. Inner and lower branches are affected first because humidity is higher there, and the disease progresses upward and outward over successive years. Severely affected trees may retain only the current year's needles at branch tips.

Affecting 25 regions

Stigmina/SNEED Needlecast

HIGH
Fungus

A fungal disease of spruce very similar in appearance to Rhizosphaera needlecast but caused by a different fungus. Often occurs alongside Rhizosphaera. It has become increasingly recognized as a major cause of spruce needle loss, particularly on Colorado blue spruce. Diagnosis requires microscopic examination to distinguish from Rhizosphaera.

Affecting 20 regions

Cytospora Canker

HIGH
Fungus

A common fungal disease of spruce and other conifers that causes branch dieback, typically starting from the lowest branches and progressing upward. Colorado blue spruce and Norway spruce are especially susceptible. The fungus enters through wounds or stressed tissue. White resin bleeding on bark is a hallmark sign. Stressed trees are most vulnerable.

Affecting 25 regions

Verticillium Wilt

HIGH
Fungus

A soilborne fungal disease that affects hundreds of plant species including maples, elms, redbuds, and many other trees. The fungus invades through roots and colonizes the vascular system, blocking water transport. Symptoms often appear suddenly on individual branches. Maples are particularly susceptible. Olive-green to brown streaking in the sapwood is diagnostic.

Affecting 27 regions

Bronze Birch Borer

HIGH
Insect

A native North American wood-boring beetle that attacks birch trees, especially paper birch and European white birch in landscape settings. Larvae feed under the bark in a serpentine pattern, disrupting nutrient and water transport. Dieback starts at the top of the crown and progresses downward, the opposite pattern of many other pests.

Affecting 26 regions

Emerald Ash Borer

MODERATE
Insect

An invasive wood-boring beetle native to Asia that has killed hundreds of millions of ash trees across North America since its discovery in Michigan in 2002. Larvae feed on the inner bark, disrupting nutrient and water transport.

Affecting 36 regions

Ips Bark Beetles

MODERATE
Insect

A genus of bark beetles that attack stressed and weakened pines throughout North America. While they typically colonize dying trees, drought and overcrowding can trigger outbreaks that kill healthy timber.

Affecting 19 regions

Dothistroma Needle Blight

MODERATE
Fungus

A fungal disease of pines that causes premature needle loss and can significantly reduce growth and vigor. It affects many pine species but is especially damaging to Austrian, ponderosa, and Monterey pines. It has increased in severity with climate change.

Asian Lady Beetle

MODERATE
Insect

Found alive but in terrible shape. Was swimming around in the water bowl we put out for feral cats here. Also appeared to have had a run in with a spider web, as it had something stuck all over it. Got a lot of suggestions for fungi and parasitoids that target ladybeetles, so maybe its appearance is more a function of a disease or parasite process taking place. It was definitely having trouble getting adound, but could be due to having been in the water for a long time and/or having bits of web
