Spruce Beetle Remains Most Deadly Forest Pest

Insects and disease have been a huge problem for trees around Colorado for decades. There is one type of beetle that is the most problematic, according to Colorado State Forest.
It’s all about the spruce beetle. Understanding this threat is important to keep the pests to a minimum and protect the trees.

The Problem of Spruce Beetles

In 2021, around 53,400 acres of Engelmann spruce forests in Colorado were affected by spruce beetles. Previously unaffected areas are now starting to be affected, these include Chaffee and Park County forests.

Out of all bark beetles, spruce beetles are proving to be the most problematic. Douglas-fir beetles are also a problem, but not on the same level as spruce beetles. This is all despite the numbers of spruce beetles declining over recent years.

The beetles damage the trees, leading to disease and death. This then increases the risk of wildfires as the trees start to offer the perfect fuel for spreading fires.

Why Are Spruce Beetles So Problematic?

What’s with the growing spread? It’s all linked to drought conditions in Colorado. The temperatures and chances to precipitation levels lead to a tree’s natural defenses dropping. More bark beetles are able to survive in the conditions, leading to issues for the trees.

All types of bark beetles are favoring the rising temperatures. There are more and more above-average temperatures recorded between June and December each year, leading to more of a drought problem unless steps are taken to protect the area.

Other Problematic Beetles in Colorado

While spruce beetles are the worst of them all, there are other bark beetles that are causing problems. As mentioned, the Douglas-fir beetle is a problem for this type of tree.
Warm conditions are also leading to an increase in piñon Ips beetle. These beetles are affecting the piñon-juniper forests, covering around 17,600 acres in 2021.
Another type of native bark beetle to look out for is the roundheaded pine beetle. This type of beetle loves the dry conditions in southwest Colorado, and it is affecting forests around la Plata, Dolores, and Montezuma counties.

Ariel surveys are used regularly to keep track of the problem. By understanding the species and the reasons why they’re growing as a concern, we can all do our part to help protect the trees, thereby protecting the wildlife and the area from wildfires.
