A federal judge in Montana has once again ruled that the U.S. Fish and Wildlife Service violated the Endangered Species Act when it excluded Colorado from a critical habitat designation for threatened lynx. In the end, the rare cat may yet get some protected sanctuaries in the Colorado high county.
Findings can help oil and gas operators minimize seismic risks
For nine months, oil and gas companies pumped 250,000 barrels of industrial wastewater deep underground in the fossil fuel sacrifice zone around Greeley, Colorado — and then, the Earth burped.
On the last day of May, 2014, the wastewater triggered a magnitude 3.2 earthquake that for some area residents felt like a truck hitting their house. The quake was the first in the area in about 40 years, fitting a regional pattern of earthquakes linked with fracking.
Now, a new study by scientists with the U.S. Geological Survey and the University of Colorado shows it may be possible to lessen the risk of frack-quakes by controlling the amount of wastewater being pumped into the ground, and by carefully monitoring seismic activity in fossil fuel development areas.

Draft document highlights global warming threats to state
Colorado Governor John Hickenlooper says a “shifting climate” threatens many of the state’s vital industries, including skiing and agriculture, and he wants the state’s power plants to cut greenhouse gas emissions by 35 percent in the next 15 years from 2012 levels. The goals are outlined in a draft version of an executive order on mitigating and adapting to climate change, which spells out some specific threats of global warming that are already well-known, including:
Greater air pollution will lead to a more hospital admissions and increased cases of respiratory illness;
Changes in precipitation can adversely impact the amount and quality of Colorado’s water resources;
Changes in runoff patterns, intense precipitation, and rising temperatures can negatively affect food production and result in greater risk of food contamination and waterborne illness.
Research to help shape efforts to reduce dangerous air pollution
By Bob Berwyn
Emissions from oil and gas production along the Colorado Front Range are a significant, measurable part of the region’s chronic summer ozone problem, scientists concluded after taking a close look at air pollution during an extensive research project in the summer of 2014.
Ozone levels in the area often spike above 70 parts per billion, a level deemed by the EPA to be dangerous to human health and to the environment, causing respiratory problems and damage to plants. About 17 ppb of that ozone are produced locally; about 3 ppb come from oil and gas industry emissions, according to a new study, published in the Journal of Geophysical Research.
State plans predator control research on Roan Plateau
Colorado wildlife managers say they are set to start a three-year study on whether killing bears and mountain lions can help boost deer populations in the northwestern part of the state, where hunting is a big part of the local economy.
According to Colorado Parks and Wildlife, mule deer populations remain below objective in the state’s largest mule deer herds in the Piceance Basin. Part of a 2015 strategy to boost those numbers is predator control, which is not a popular concept with some wildlife advocates, who believe that habitat fragmentation from oil and gas development is probably a bigger factor in the long-term decline of deer herds.

Dusting off a few more from the Summit Voice archives for a Sunday set highlighting some of the things I love most: snow and trees. From aspens in the Williams Fork Range to the red rocks of Glenwood Springs Canyon, there’s incomparable beauty in the hills of Colorado, and nothing like a little snow to make it all shine!
Non-native predators could threaten endangered species in Colorado River
Colorado wildlife managers will try to curb expansion of non-native northern pike in Summit County’s Green Mountain Reservoir by paying anglers a $20 bounty for each fish they deliver to the Heeney Marina.
The illegally introduced fish are taking a toll on trout in the reservoir north of Silverthorne and could escape to the Blue River and make their way to the Colorado River. That could add to the challenges of trying to recover four endangered native Colorado River fish species, according to Colorado Parks and Wildlife.
