Forests: Spruce beetles spreading fast in southern Rockies

State report details status of insect activities

Spruce beetles are widely active across the mountains of southern Colorado.

Staff Report

FRISCO — Windstorms, mild winters and drought are the key factors in the continued spread of spruce beetles, which have become the dominant change agent in Colorado forests the past few years.

According to the latest annual forest health report compiled by state forest experts, spruce beetles were active across 398,000 acres in 2013, affected more than triple the amount of acreage than mountain pine beetles. Continue reading

Logging no panacea for pine beetle outbreaks

Can we log our way to forest health?

Science sometimes missing from forest management policies

By Bob Berwyn

FRISCO — While politicians and policy makers continue to conflate a number of complex forest health and wildfire issues, a new study suggests there’s little evidence supporting the idea that logging helps to control or contain the spread of tree-killing pine beetles.

Nobody disputes the need to clear trees, brush and other fuels from around homes in fire-prone forest areas, but some lawmakers who should know better have been pushing for more logging under the guise of restoring forest health and as an antidote to insect infestations.

The idea that speedy approval of logging projects could help restore forest health was also used as a basis for short-cutting environmental reviews for logging projects, possibly resulting in negative long-term environmental impacts in forests.

But forest researchers in California and Montana said there isn’t much monitoring to assess the effectiveness of logging, and that failures often aren’t reported, probably because they don’t fit the popular narrative. Continue reading

Colorado: As pine beetle epidemic passes, politicians still pushing for more logging

Budget woes still hindering forest restoration efforts

FRISCO — The Colorado high country may be buried in snow right now, but lawmakers and fire experts are already brainstorming about the upcoming wildfire season.

As part of that process, Sen. Mark Udall (D-Colo.) met with local officials in Summit County recently to get feedback on recent successes and remaining challenges in forest management and wildfire mitigation policies and actions.

“It’s not a question of if we’re going to have more megafires, but when,” Udall said, without ever mentioning global warming as a key factor in the wildfire equation. Continue reading

Good news, bad news for Colorado forests

Pine beetle infestation slows, but spruce beetles continue to spread

FRISCO — There’s good news and bad news for Colorado forests, according to state and federal officials, who said last week that the mountain pine beetle epidemic slowed dramatically in 2013, while spruce beetles continued to spread.

Statewide, mountain pine beetles were active on 97,000 acres in 2013, the lowest acreage of active infestation in 15 years. Since 1996, mountain pine beetles have killed trees across 3.4 million acres.

Spruce beetle were active on 398,000 acres, expanding by 216,000 new acres in 2013, compared to 183,000 new acres in 2012. The total area affected by this beetle since 1996 has reached more than 1.1 million acres. Continue reading

Colorado ready to grant $5.2 million for wildfire risk reduction projects on non-federal lands

Heavy machinery is on the move in the quest to restore Summit County's forests.

Heavy machinery is on the move in the quest to restore Colorado’s forests.

Applications due March 13

Staff Report

FRISCO — Neighborhoods looking to reduce wildfire threats can now apply for grants under a state program that will disburse a total of $5.2 million for projects that reduce the risk for damage to property, infrastructure, and water supplies, and those that limit the likelihood of wildfires spreading into populated areas.

The grant program, administered by the Colorado Department of Natural Resources, is accepting applications through March 13. The grants will be awarded in early May. Information and applications are online at the DNR website. Continue reading

Forests: New CU-Boulder study shows nuances in tree-killing pine beetle epidemic

Smooth-barked trees better able to repel insects

By Summit Voice

FRISCO — Lodgepole and ponderosa pines with smoother bark may be better at repelling tree-killing bugs, according to Boulder-based researchers with the University of Colorado.

The new findings may help forest managers as they plan logging projects, especially in areas where there is a need to protect high-value trees — in developed recreation areas or on private property.

The study was published online in the journal Functional Ecology. While the current pine beetle epidemic has slowed dramatically in many areas, it wiped out millions of trees across 3.4 million acres since 1996. Continue reading

In the absence of fire, intensive mechanical treatments needed to keep ponderosa pine forests healthy

Before: Plenty of healthy grasses, forbs and shrubs, along with young lodgepole pines two to three feet tall.

Shrub removal also key to moderating fire behavior

By Summit Voice

FRISCO — Forest Service scientists say they’ve quantified the relationship between the density of ponderosa pine stands and disease.

The study shows that — no surprise — increased density, mainly due to the agency’s long-term fire suppression policies, makes the trees more susceptible to bark beetles and diseases. Competition for soil moisture, nutrients, and sunlight  in dense stands weakens trees and therefore also contributes to fuel buildup. Continue reading
