Seismic blasting east of Greenland raises concerns about impacts to marine mammals

Staff Report

FRISCO — The Arctic Ocean north of Alaska isn’t the only area increasingly at risk from oil and gas exploitation. Oil companies are exploring the seabed off the eastern coast of Greenland, and the seismic blasting is likely harm whales and other marine life.

Oil companies use seismic equipment to map underground oil and gas reserves with airguns that emit 259 decibel blasts, a sound intensity would be perceived by humans as approximately eight times louder than a jet engine taking off. Continue reading

El Paso research shows strong link between school performance and air pollution

Staff Report

FRISCO — A new children’s health study by researchers at the University of Texas at El Paso reinforces existing evidence that exposure to toxic air pollution from cars and trucks has a big effect on school performance.

The UTEP study found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower GPAs. The findings are based on an analysis of academic performance and sociodemographic data for 1,895 fourth and fifth grade children in the El Paso Independent School District. Continue reading

Is the EPA doing enough to protect bees?

Beekeepers accuse pesticide industry of trying to ‘hijack’ public policy

FRISCO — The public comment period for proposed EPA rules on bee-killing pesticides may be over, but the battle over pesticide policies will continue, as conservation groups suspect that the pesticide industry may have exerted undue influence over the rule-making process.

Those concerns are reinforced by some of the country’s beekeepers, who say the proposed rule doesn’t do enough to address federal responsibility to address the impact of pesticides on bee deaths. The Pollinator Stewardship Council recently submitted a letter to the EPA detailing its concerns about the proposed new rule. Continue reading

Morning photo: Mountain colors

Dawn patrol … and more

FRISCO —What could be better than a rainbow stretched across the jagged skyline of the Tenmile Range? Maybe the scattered rays of the morning sun coming up over the Continental Divide, or the vibrant buzz of a bumblebee perched on purple thistle, or deepening purple and orange clouds over Frisco’s landmark Peak One. It’s tough to choose, that’s for sure, so I’m glad I don’t have to pick just one favorite image from this week’s photo wanderings in Summit County. If you love these shots, check out the online Summit Voice gallery, where a purchase goes a long way toward supporting independent Colorado environmental journalism.

Another piece in the sage grouse puzzle …

Staff Report

FRISCO — After closely studying a greater sage-grouse subpopulation on the Columbia Plateau in eastern Washington, wildlife biologists said that power lines may be a greater factor in habitat fragmentation than previously believed.

The new study found that transmission lines from hydroelectric dams and wind turbines affect greater sage grouse habitat by isolating fragile populations and limiting movement. The was published online this summer in the journal Landscape Ecology.

“With only a fraction of pre-settlement habitat left in the state for this species, it’s key that all of that habitat be connected in order for the population to be viable in the future,” said lead author Andrew Shirk, a research scientist with the University of Washington’s Climate Impacts Group.

Upcoming seminar spotlights regional water issues

CRWCD’s annual water seminar features leading national and regional water and climate experts

Several weekend stories addressed water quailty issues.

Got water?

Staff Report

FRISCO — Colorado this summer may have escaped the severe drought plaguing much of the West — at least for now — but that doesn’t mean the state is immune from regional water woes.

Planners and water users know very well that huge long-term challenges remain for all the states in the Colorado River Basin, and some of those issues will be highlighted during the Colorado River Water Conservation District’s Sept. 10 water seminar in Grand Junction.

Two of the most important women in Western water leadership will be addressing the Colorado River District’s popular Annual Water Seminar in Grand Junction, Colo., that takes place Thursday, Sept. 10, 2015, from 9 a.m. to 3:30 p.m. at the Two Rivers Convention Center. Continue reading

Wildlife managers have closed several areas this summer due to bear activity and to avoid unwanted encounters

Staff Report

FRISCO — After earlier summer closures of popular national forest areas due to close encounters with bears, Denver Water and Colorado Parks and Wildlife have decided to close Waterton Canyon to public recreation until further notice — for the same reason.

According to a release from Denver Water, there are two sows, each with twin cubs, and other bears actively foraging in the canyon. Friday afternoon, a biker was chased by a bear in the canyon. No one was injured. Continue reading
