The mountain pine beetle has killed large numbers of the lodgepole pine trees in the northern mountains of the US state of Colorado. Chemical prevention is effective but too costly for large-scale use. If not removed the dead trees increase the incidence of wildfires, and may contribute to climate change as they decay. Uses have been found for the dead wood including composting and in construction, and potentially to make biochar.
The beetles infest the lodgepole pine, which makes up 8% of Colorado’s 22 million acres (89,000 km2) of forests. Lodgepole pines are found at elevations between 6,000-11,000 feet. A previous notable outbreak occurred in Colorado in the 1970s but was significantly less detrimental than the current infestation. Of the 1,760,000 acres (7,100 km2) of lodgepole pine, about 70% have been damaged. High temperatures have allowed beetle infestations at higher elevations. According to a recent study, pine beetles have expanded their infestation by 400,000 acres (1,600 km2). The infestation is primarily concentrated in the state’s northern mountains. The infestation has been moving north and east from the Granby and Winter Park area towards Larimer County. It is estimated that beetle kill will leave behind a deforested area the size of Rhode Island.
Uses of beetle kill wood
Although beetle kill has resulted in a significant amount of dead trees, there are some options for use of the trees after they are killed. For instance, Summit County has begun composting by combining wood chips from beetle kill trees with other organic materials. By doing this, they are creating a product that could be used in landscaping and re-vegetation projects.
The ancient practice of biochar is also emerging as an option. A product of the bio char process is a synthetic gas that can be used as fuel. Some forestry experts predict this fuel can be used to power plants where beetle kill wood is processed.
Beetle kill wood is also being used in local projects. Multiple housing complexes are beginning to use beetle kill wood to replace sidings of houses, like a condo complex at Copper Mountain which is replacing old siding with blue-stain wood, which is named for the dark color in the wood that is caused by fungus carried by the pine beetle. Local Interior Designer Drew Witmer is experimenting with the wood and used it to build the fixtures in the Jiberish clothing store. Denver Design Build used the material to build many of the fixtures used by the US Open of Snowboarding.
Another company, owned by Randy Piper, GreenWay Building Products, LLC markets and distributes beetle kill wood from Colorado for flooring, paneling, and siding. GreenWay's 'blended value' business model seeks to bring social and environmental benefits together with an economic model that allows both public and private landowners to reduce or eliminate the cost of treating affected lands.
The Beetle Kill Trade Association has been established to “to unite and align the self interests of business invested in or interested in the removal and recycling of standing beetle killed lodgepole pines in order to remove obstacles to the creation of a viable, vibrant and sustainable market for products utilizing beetle kill pines as raw material.”
There are different views regarding beetle kill in Colorado. Some view it as a natural cycle while others believe it should be prevented. Unfortunately, such prevention measures are very expensive and not practical. Chemical treatments applied to lodgepole pines in the spring is effective, but the costs are $50 per tree in addition to annual treatments as needed.
Werner Kurz has pointed out that hundreds of millions of tons of carbon will be released into the atmosphere as the dead timber decays or burns, contributing to climate change that may further devastate Western forests. He advocates logging most of the dead trees and replanting quickly.
Although human efforts to stop beetle kill outright in Colorado may be futile, some are taking measures to help alleviate the side effects of beetle kill, such as wildfires. Currently, measures are being taken by Colorado politicians to help this issue gain attention nationwide. State Rep. Christine Scanlan, D-Dillon, and state Sen. Dan Gibbs, D-Silverthorne, have testified that wildfires caused by beetle kill could be detrimental to the nation's water supply and damage the nation's electrical grid. In doing this, they hope to help Colorado receive more federal funding for forest fire prevention and water purification that occurs because of beetle kill.
