Environment: More signs of coral damage from BP’s 2010 Deepwater Horizon oil disaster

Coral reefs miles away from the Deepwater Horizon oil disaster were afffected by the spill.

Ecological footprint of oil spill spread farther than previously believed

Staff Report

FRISCO — Oil from the 2010 Deepwater Horizon oil disaster soiled seafloor corals more than 12 miles from the spill site, Penn State University researchers said after doing a detailed survey of the area.

“The footprint of the impact of the spill on coral communities is both deeper and wider than previous data indicated,” said Penn State biology professor Charles Fisher. “This study very clearly shows that multiple coral communities, up to 22 kilometers from the spill site and at depths over 1800 meters, were impacted by the spill,” Fisher said.

The oil from the spill in the Gulf of Mexico has largely dissipated, so other clues now are needed to identify marine species impacted by the spill. Fisher’s team used the current conditions at a coral community known to have been impacted by the spill in 2010 as a model “fingerprint” for gauging the spill’s impact in newly discovered coral communities.

FRISCO — Crowdfunding isn’t just for journalism and tech start-ups anymore. These days, entire communities have joined in the action, with towns seeking direct support for projects, like in Liverpool, England, where a new playground was funded after a project was successfully funded on Spacehive, a platform for community projects.

At Summit Voice, we only have three days left to reach our goal of $5,000 to support two months of intensive environmental journalism that will look at the effects of global warming in the Rocky Mountains, and we need your help to reach the target. Thanks to the readers and subscribers who have already generously helped with pledges of support. Please visit our crowdfunding page for all the details and to make a pledge now: http://www.beaconreader.com/projects/rocky-mountain-climate-rangers?updated=1. Continue reading

Biodiversity: Some progress for Mexican gray wolves?

Feds propose updates to management of Southwest wolves

FRISCO — Rare and beleaguered Mexican gray wolves may get a little more room to roam in the Southwest, as the U.S. Fish and Wildlife Service proposes changes to a recovery plan from the species, including new releases of captive-bred wolves to bolster wild populations.

The new releases could happen in new areas of New Mexico and parts of Arizona where there are no wolf packs yet, and the federal agency’s proposed changes would also allow wolves to roam from the Mexican border to Interstate 40, a much broader region than currently permitted.

Only 83 Mexican wolves live in the wilds of the Southwest, including just five breeding pairs. Scientists have shown that inbreeding caused by a lack of wolf releases to the wild, coupled with too many killings and removals of wolves, is causing smaller litter sizes and lower pup-survival rates in the wild population. Expanding wolf releases to New Mexico’s Gila National Forest, in particular, would enable managers to diversify the population through new releases and diminish inbreeding. Continue reading

Oceans: Pacific bluefin tuna on the brink as feds seek input on new fishing regulations

FRISCO — Pacific bluefin tuna won’t last long at any sustainable level without immediate and drastic intervention by fisheries managers, according to ocean advocates who are urging the federal government to adopt strict limits on bluefin tuna catch.

Overall, many tuna populations are on the brink of collapse. Five of eight tuna species have been assigned threatened or near-threatened status on the international Red List maintained by the International Union for the Conservation of Nature.

In the Gulf of Mexico, for example, the Deepwater Horizon oil disaster spewed millions of gallons of oil into the species’ prime breeding grounds, and a 2010 report by the International Consortium of Investigative Journalists showed how illegal fishing and inadequate enforcement are decimating tuna stocks all over the world.

FRISCO — Yes, it’s fun to visit foreign locales, sample exotic food and take photos of new and different subjects. But you don’t always have to venture far to get a good shot. All the images in this set were taking in places where we walk our dogs on a daily basis, in some cases, right in our neighborhood, or more accurately where our neighborhood edges against the open space at the edge of Dillon Reservoir. Sometimes it’s just a matter of finding a new perspective in a familiar place.

Environment: Ongoing cleanup tackles toxic Peru Creek

July 30 site visit gives public a chance to see progress in $3 million remediation project at abandoned mine in Summit County

Staff Report

FRISCO — With recent increases in levels of toxic metals in Peru Creek, the ongoing remediation work at the abandoned Pennsylvania Mine, near Keystone, Colo., takes on an even greater importance in the context of water quality in the Blue River Basin and the Upper Colorado.

The mine, which produced huge amounts of silver 100 years ago, has been pinpointed as one of the main sources of acid mine drainage. Water seeping through the rocky ground trickles into the old mine workings, picks up contaminants along the way, then percolates back into Peru Creek near the head of the beautiful alpine valley.

During the last couple of summers, scientists and engineers have been working to reduce the pollution, and this coming week (July 30) there will be a public field trip to the site, led by Jeff Graves of the Colorado Division of Reclamation Mining and Safety, as well as other members of the Snake River Task Force.

Environment: USGS study shows neonicotinoid pesticide pollution common in Midwest streams

Concentrations in some streams are high enough to kill aquatic organisms

By Summit Voice

FRISCO — Scientists with the U.S. Geological Survey studying streams in the Midwest have found levels of neonicotinoid insecticides at up to 20 times the concentrations deemed toxic to aquatic organisms. The systemic pesticides have raised concerns because they’ve been linked with honey bee declines.

Traces of the chemicals were widespread in streams throughout the region — not surprising in the heart of the country’s agricultural belt. In all, nine rivers and streams, including the Mississippi and Missouri Rivers, were included in the study. The rivers studied drain most of Iowa, and parts of Minnesota, Montana, Nebraska, North Dakota, South Dakota, and Wisconsin. These states have the highest use of neonicotinoid insecticides in the Nation, and the chemicals were found in all nine rivers and streams. Continue reading
