Somebody is trying to take away your public lands

Congress once again toys with extremist agenda

Staff Report

Congress may not be able to get it together to deal with issues like crumbling infrastructure or deadly opiate epidemics, but when it comes to trying to strip Americans of their unique public lands heritage, there’s no shortage of legislation.

The Center for Biological Diversity is warming there are four bills pending in the House and Senate natural resource committees that could affect public lands — and not in a good way. One of the measures would block the creation of new national monuments and parks, while others could enable the transfer of federally managed public lands to state governments.

Climate change may be factor in spread of tree fungus

Signs of hope? A single Douglas-fir grows at the base of the clearcut area along Swan Mountain Road. It'll be interesting to watch the area during the next few years to see how it regenerates.

Commercially valuable tree stands take hit in Pacific Northwest

Staff Report

Global warming may be a factor in the spread of a fungus affecting valuable Douglas fir forests in the Pacific Northwest. Needle cast disease has recently spread across 590,000 acres in Oregon,  quadrupling since the start of surveys in 1996. The annual economic loss has been estimated at $128 million.

“The correlation between disease severity and climate factors, such as spring moisture and warm winter temperatures, raises the question of a link between disease expansion and climate change,” said  researcher Gabriela Ritokova. “Those factors, in combination with lots of Douglas fir and with large springtime fungal spore production, have us where we are now.” Continue reading “Climate change may be factor in spread of tree fungus”

Forests may not benefit from rising CO2 levels

Study says disastrous tipping points could be reached by 2050

Staff Report

Forests of the future may not be able to remove heat-trapping CO2 from the atmosphere as effectively as previously thought, scientists said in a new study that’s based on an extensive analysis of tree ring data from the past.

“We utilized a network of more than two million tree-ring observations spanning North America. Tree-rings provide a record into how trees that grow in different climates respond to changes in temperature and rainfall,” said Brian Enquist, a professor in the UA’s Department of Ecology and Evolutionary Biology and a fellow of the Aspen Center for Environmental Studies in Aspen, Colorado.

The research challenges assumptions about how forests will respond to warmer average temperatures, increased greenhouse gas emissions, and shifting rainfall patterns. It also suggests that the warming climate already is rapidly pushing many forests towards an ecological tipping point, which may be reached as early as 2050, Exposure to unprecedented temperatures hampers tree growth and makes them susceptible to other stress factors.

Court deal a win for fee-free public lands access in SoCal

Settlement addresses pesky Adventure Pass fees on 4 Southern California national forests

Staff Report

A long-running and stubborn battle by activists against the spread of public lands access fees has paid off once again in Southern California, where the U.S. Forest Service agreed to designate and mark free parking areas for hikers who aren’t using developed facilities.

The court-sanctioned deal stems from yet another legal battle over federal recreation fees. Public land agencies started charging for access to plug alleged budget holes; public lands advocates have been trying to limit the spread of the fees and make sure they’ve only levied in the places specifically authorized by Congress — namely at developed recreation sites, and not just for general hiking access.

California tree deaths part of global wave of forest mortality

Climate change is wiping out forests on a staggering scale

Staff Report

California’s multiyear drought killed even more trees than previously thought, the U.S. Forest Service announced this week. Aerial and ground surveys show that 26 million trees across six counties in Southern California died, in addition to the 40 million trees that died statewide from 2010 to October 2015. Four years of drought, high temperatures and an outbreak of tree-killing bark beetles all contributed the historic levels of tree die-off, the agency said.

The tree mortality in California is the latest crest in a wave of forest die-offs in the past few decades linked with global warming. In the Southwest, an outbreak of ips beetles after the 2002 drought killed 80 percent of the piñon pine forests in the Four Corners region.

Around the same time, pine beetles started spreading across northern Colorado, parts of Wyoming and North Dakota, ultimately killing millions of acres of forest. And just as the pine beetle infestation waned, a spruce beetle outbreak in southern Colorado started to spread. Since 1996, spruce beetles have killed trees across about 1.5 million acres of forest.

Huge swaths of Colorado aspen forests also died in the early 2000s in a mortality event linked with extreme heat, and forest researchers say hardwood forests in the northern U.S. are also at risk from global warming. Continue reading “California tree deaths part of global wave of forest mortality”

Environment: Can prescribed fires make forests more resilient?

New study focuses on drought-stricken California forests

Beetle-killed forests now dominate the landscape in Summit County. Prescribed fires are needed to help regenerate forests and clear dangerous fuels, according to White River NF supervisor Scott Fitzwilliams.

Staff Report

A rising tide of insect infestations, tree mortality and wildfires — all caused by global warming — has resulted in political pressure for more logging in U.S. Forests, but there’s plenty of research showing that cutting down trees doesn’t do much good and can even increase the fire danger.

Exploring alternative options for strengthening forest resiliency, researchers with the U.S. Geological Survey and the National Park Service recently found that thinning forests with prescribed fires can reduce drought.

U.S. wildfire season on pace to break last year’s record

Global warming a key factor in surge of giant forest blazes

By Bob Berwyn

With about 1.5 million acres already scarred by wildfires across the U.S. this year, Agriculture Secretary Tom Vilsack is warning of a long, hot fire season ahead. Following a meeting with regional Forest Service leaders, Vilsack, along with Forest Service Chief Tom Tidwell, said that federal budgets are not keeping pace with the steep increase in fires.

Vilsack said 2015 was the most expensive fire season in the department’s history, costing more than $2.6 billion on fire alone.

“The 2016 wildfire season is off to a worrisome start. Southern California, the Great Basin in Nevada, portions of the southwest, and even Florida and Hawaii are particularly vulnerable this year,” Vilsack said. The sustained California drought killed more than 40 million trees, which are all potential fuel, and projections for hot summer weather, driven by global warming and a massive El Niño hangover, will likely increase the danger even more, he added.
