More wilderness in Southern California?
Roadless lands to be evaluated for wilderness qualities
FRISCO —In a rare administrative reversal, regional U.S. Forest Service officials told the Los Padres National Forest to reconsider its plans for seven roadless areas encompassing more than 220,000 acres in Santa Barbara, Ventura and Kern counties.
The decision directs forest planners to reevaluate the wilderness characteristics of seven areas and clarify how biologists will monitor and protect imperiled wildlife. Continue reading

New website offers glimpse of ongoing efforts to ‘de-federalize’ the West
FRISCO — On and off efforts to force the transfer of federally managed public western lands to individual states have grown beyond campaign rhetoric.
These days, there’s a semi-organized effort on the part of lawmakers in several western states to try and take over millions of acres of forests and rangelands. The history of the so-called Sagebrush Rebellion, with roots in the Reagan era, is outlined in detail on this University of Colorado website. Continue reading

A new study finds that human disturbance drives forest changes in eastern U.S. bberwyn photo
Fire suppression, land-clearing outweigh climate factors, study says
FRISCO — Climate change may only be a secondary factor in the changing composition of Eastern forests. Changes in disturbance regimes have had a much bigger impact in the past century or so, according to Marc Abrams, a researcher in Penn State’s College of Agricultural Sciences.
Abrams says eastern forests are still in a state of disequilibrium resulting from massive clear-cutting and burning during the late 1800s and early 1900s, and aggressive forest fire suppression has also had a far greater influence on shifts in dominant tree species than minor differences in temperature.

Predator restoration stirs the ecosystem pot
By Summit Voice
FRISCO — Long term ecological monitoring in Yellowstone National Park shows a surge in aspen growth following the restoration of wolves to the ecosystem, with overall shifts in landscape conditions not seen in more than a century.
A series of studies show the recovery of vegetation as elk numbers drop, a decline driven by the return of the region’s apex predators. Biologists long hypothesized that wolves keep elk populations in check and also affect their grazing habits. Continue reading

The U.S. Forest Service this week eradicated an illegal marijuana growing operation in Colorado.
Feds say illegal marijuana growing is harmful to the environment
FRISCO —Colorado’s legalization of marijuana may mark a new era on the state level, but some things haven’t changed. Each year, profiteering outlaws try to use public lands to grow and harvest marijuana, which remains illegal under federal laws.
This week, law enforcement officers with the U.S. Forest Service eradicated a major pot farm on national forest lands near Ruedi Reservoir after it was reported to the Forest Service by the public. After uprooting more than 2,600 mature plants, Forest Service officials estimated the value of the plants about $6 to $8 million based on the average value of $2,500 per pound. Continue reading

Study shows no clear link between beetle-kill and ecological severity of western wildfires
FRISCO — For all their frenzied tree-killing during the past 10 years, mountain pine beetles haven’t been a big factor in the ecological severity of wildfires in the West, a team of university scientists said this week.
Weather and topography are the main factors in determining how much damage a wildfire does to forest ecosystems, according to the researchers with the University of Wisconsin-Madison and the Washington State Department of Natural Resources.
The new study, published in the Proceedings of the National Academy of Sciences, provides some of the first rigorous field data to test whether fires that burn in areas impacted by mountain pine beetles are more ecologically severe than in those not attacked by the native bug. The study didn’t look at fire behavior, including how fast they spread or how dangerous they are to fight. Continue reading

A new study examines the history of wildfires along the Colorado Front Range.
Historic wildfires in the pre-suppression era burned just as intensely, scientists say
FRISCO — New research challenges the conventional wisdom that wildfires along the Colorado Front Range have become more severe.
A detailed assessment of fire history across more 1 million acres of forest suggests that only 16 percent of the area showed a shift from historically low-severity fires to severe, potential crown fires that can jump from treetop to treetop.
Even in the days before fire suppression, fires along the Front Range were often destructive, killing many mature trees in the burn areas, the study concluded. Continue reading
