Findings challenge carbon-balance assumptions of woody biomass energy boosters

FRISCO — Logging forests may have a more significant impact on carbon storage in soils than previously believed, Dartmouth College researchers found after taking a close look at at how timber harvesting affects mineral soil carbon over 100 years.
The study found that, while logging doesn’t immediately release carbon stored in a forest’s mineral soils into the atmosphere, it triggers a gradual release that may contribute to climate change over decades. Continue reading

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

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

Plenty of healthy grasses, forbs and shrubs, along with young lodgepole pines two to three feet tall in this unlogged patch of beetle-killed pines.
Shrub removal also key to moderating fire behavior

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

New study helps quantify logging as part of the forest carbon cycle
By Bob Berwyn
FRISCO — Scientists and resource managers have long been trying to solve the carbon-balance equation from using wood for energy, but they may have to add a new factor to their calculations.
A research team led by scientists with Dartmouth College found that logging releases large amounts of carbon from the soil. The processes by which that happens aren’t completely understood, but the findings suggest that calls for an increased reliance on forest biomass should be re-evaluated.
Forest carbon analyses are incomplete unless they include deep soil, which stores more than 50 percent of the carbon in forest soils, said Dartmouth Professor Andrew Friedland, one of the co-authors of the paper recently published in the journal Global Change Biology. Continue reading

Logging company leaves numerous spills, damaged vegetation

FRISCO — Forest Service officials with the Dillon Ranger District said they will investigate several small oil spills at a long-term logging camp at the abandoned campground at Officers Gulch.
The agency authorized the logging crew’s stay at the site, where several people lived in campers most of the winter and stored equipment and fuel. In one area, diesel fuel leakage from an old generator spilled off the pavement and into the forest and other spills of unknown materials are visible in the camping area.
In other places, numerous limbs were slashed off young lodgepole pines, presumably to give large trucks room to maneuver in and out. In other spots, snowplows used to clear access to the site in the winter uprooted willow bushes and broke down other trees. Continue reading

Proposed Senate bill would require widespread national forest logging

By Summit Voice
SUMMIT COUNTY — Federal land managers could get wider authority for more backcountry logging under a new bill proposed in the U.S. Senate by Michael Bennet (D-CO), along with co-sponsors Mark Udall (D-CO), Ron Wyden (D-OR), and Max Baucus (D-MT).
The National Forest Insect and Disease Treatment Act is being pitched as a way to help Forest Service treat insect and disease epidemics and promote overall forest health. As drafted, it directs the agency to treat threatened watersheds while prioritizing preservation of old-growth and large trees when possible. Continue reading
