New study eyes impacts to aquatic insects

Staff Report

Using a vast sample of data collected in a citizen science project, researchers say they’ve been able to discern how hydropeaking affects aquatic insects that form the base of river food chains. The information could help resource managers develop alternative hydropower practices that aren’t as harmful to ecosystems, according to a new study published in the journal BioScience.

Hydropeaking refers to the practice of increasing river flows at times of peak demand, generally during the day. This study shows how abrupt water level changes affect aquatic insects in every stage of life. The research was done by scientists with the U.S. Geological Survey, Oregon State University, Utah State University and Idaho State University.

Conservation groups, Native Americans united in bid to oppose real estate speculation near national park

Staff Report

The U.S. Forest Service has nixed a tentative plan to develop a new mega-resort near the South Rim of Grand Canyon National Park.

As proposed in April 2015, the the plan would have resulted in major real estate sprawl around the village of Tusayan, with up to 2,100 residential units and 3 million square feet of retail space along with hotels, a spa and conference center.

The Forest Service had to decide whether to permit road and infrastructure improvements on publicly owned lands near the Grand Canyon that would have facilitated the development. Last week,  Kaibab National Forest Supervisor Heather Provencio rejected the plan. Continue reading “Forest Service rejects development bid near Grand Canyon”

2015 in Review: Public lands

Energy issues drive public lands debates

Rocky Mountain National Park turned 100 years old in 2015.

Staff Report

The battle over fossil fuel exploitation on public lands heated up in 2015, as environmental advocates launched an aggressive #keepitintheground campaign aimed at convincing the Obama administration to stop issuing leases and permits for oil and gas drilling. But along with the political and environmental battles, there were also some feel-good stories. Right here in Colorado, for example, two beloved tracts of land administered by the National Park Service celebrated centennials. Read more about those birthdays here.

It was a big year for public lands preservation. With Congress gridlocked on many issues, President Obama took the initiative to set aside hundreds of thousands of acres as national monuments under the Antiquities Act, including Browns Canyon, in Colorado. Read more about the creation of Browns Canyon National Monument in these Summit Voice stories, and learn more about President Obama’s use of the Antiquities Act here.

Monument designation sought to prevent mining, preserve Native American heritage

Staff Report

Native Americans in northern Arizona are supporting far-reaching protection for culturally and environmentally important lands around the Grand Canyon.

The Navajo Nation and the Hopi, Havasupai, and Hualapai tribes have joined forces to back a bill by Congressman Raúl Grijalva (D-Ariz.) that would protect more than a million acres near the canyon.

Petition seeks new mining regulations to prevent future disasters like the Animas River spill

Common sense tweaks would require more monitoring as well as reclamation

Staff Report

FRISCO — Congress, under fierce lobbying pressure from the mining industry, may not have the political wherewithal to make meaningful changes to mining laws.

But public land agencies could tweak their regulations to reduce the chances of another event like the spill from the Gold King Mine that tainted the Animas and San Juan rivers earlier this month.

A coalition of community and environmental groups hopes to spur those changes at the Department of the Interior and Department of Agriculture with a formal petition under the Administrative Procedures Act. The petition seeks four key changes to mining rules that would go a long way toward averting future toxic spills.

The rules changes would:

  • Limit the lifetime of a mine permit,
  • Impose enforceable reclamation deadlines and groundwater monitoring requirements on mines
  • Require regular monitoring and inspections,
  • And limit the number of years that a mine can remain inactive.

Pollution runs deep in the Colorado River

The confluence of Havasu Creek with the Colorado River (river mile 157) is a popular place for boaters to stop and admire the striking blue-green water of Havasu Creek. The turquoise color is caused by water with a high mineral content. At the point where the blue creek meets the turbid colorado river there often appears a definite break.

Fish in the Grand Canyon show levels of mercury and selenium that exceed risk thresholds for wildlife

Staff Report

FRISCO — Pollution runs deep in the Colorado River, according to U.S. Geological Survey scientists who recently documented traces of mercury and selenium contamination in fish living in the Grand Canyon.

Similar studies have documented mercury contamination in fish in Rocky Mountain National Park. In the bigger picture, the USGS has also documented mercury contamination in 25 percent of U.S. streams. In the Arctic, polar bears are being exposed to similar contaminants. Continue reading “Pollution runs deep in the Colorado River”

Impacts to water quality, cultural resources at stake, as conservation groups seek new environmental study

Staff Report

FRISCO — A U.S. Forest Service decision to allow uranium mining near the Grand Canyon will be tested in court once again.

Conservation groups last week said they’ll appeal a lower court ruling that affirmed the agency’s decision on the mine, located about six miles from the South Rim of the Grand Canyon.

U.S. District Court Judge David Campbell last month said conservation groups and the Havasupai Tribe failed to show that the U.S. Forest Service violated environmental laws, but that decision will now be tested in a federal appeals court.
