New report highlights actions aimed at buffering ecosystems from climate change
FRISCO — Congress may still be dithering over global warming, but some federal agencies are on a fast-forward path to addressing climate-change impacts to natural resources.
The U.S. Fish and Wildlife Service last month unveiled a new report describing 50 projects launched to strengthen climate resiliency, including wildlife movement areas that help buffer animals from global warming and reforestation projects focusing on climate-resilient native trees.
“Across the nation, a broad coalition of natural resource agencies is working with partners and stakeholders to collectively address the current impacts and future threats of climate change,” said USFWS deputy director Rowan Gould. “The concrete actions documented in this report represent real progress, but helping native species cope with the effects of climate disruption requires us to build on these successes,” Gould said.

Salmon fisheries at risk with open-pit mine proposal
The EPA will be allowed to do a thorough evaluation of the impacts of a proposed copper mine in Alaska’s Bristol Bay, a federal judge has ruled.
By Bob Berwyn
FRISCO — A federal judge Friday ruled that the EPA can proceed with an environmental review of a proposed copper mine in Alaska’ pristine Bristol Bay.
U.S. District Court Judge H. Russel Holland rejected arguments that the EPA exceeded its authority by starting the review process in the absence of a specific permit application, and that the review violates the Alaska Statehood Act.
At issue is the proposed Pebble Mine, which would, according to environmental groups, become the largest copper mine in the world, potentially tainting huge areas of productive salmon habitat with dredged material and other pollutants. Continue reading

EPA raises questions about compliance with Clean Water Act
Denver Water plans to increase transmountain diversions through the Moffat collection system is not drawing rave reviews, as numerous entities have expressed significant concerns about impacts to water quality. bberwyn photo.
By Bob Berwyn
FRISCO — For all the detailed information in the 16,000-page study for Denver Water’s proposed new water diversions from the Western Slope, there are still more questions than answers, according to formal comment letters filed in the past few weeks.
As currently configured, the proposal to shunt more water from Colorado River headwaters streams to the Front Range could worsen water water quality in many streams that are already feeling the pain of low flows, EPA water experts wrote in a June 9 letter. Continue reading

New rule aims to clear up regulatory limbo for seasonal streams and isolated wetlands
By Bob Berwyn
FRISCO — A proposed federal rule would restore protection to hundreds of Colorado streams and big swaths of wetlands, including beloved alpine creeks and the sandy washes of the Front Range that only hold water seasonally.
The seasonal streams and disconnected wetlands long were covered under the Clean Water Act, but a pair of complex U.S. Supreme Court rulings in 2001 and 2006 opened some loopholes the regulations. At the least, the legal limbo caused headaches for scientists and regulators trying to assess impacts of housing developments and new roads. In some cases, they weren’t sure if they even had authority to regulate filling or draining of some wetlands. Continue reading

Freshwater ecosystems at risk, as salt-loving species intrude
By Summit Voice
FRISCO — A combination of sea level rise and upstream freshwater depletion is leading to a decline of the Everglades freshwater plant communities, as salt-loving mangroves spread farther inland.
Satellite imagery over the southeastern Everglades confirms long-term trends of mangrove expansion and sawgrass habitat loss near the shore, according to a new study published in the scientific journal Wetlands.
“I was very surprised at how well the results matched our understanding of long-term trends and field data. Normally, we don’t see such clear patterns,” said lead researcher Douglas Fuller. Continue reading

Measures don’t meet Clean Water Act requirements

SUMMIT COUNTY — Watchdog grous are characterizing a proposed Florida water quality plan as a give-away to polluting industries, creating even more loopholes to spew sewage, manure, and fertilizer into Florida waters, according to watchdog groups who sued the state and federal government in 2008 for their failure to set pollution limits, as required by the Clean Water Act.
“We have record numbers of dead manatees washing up on southwest Florida right now, in the prime of our tourist season,” said Earthjustice attorney David Guest. “Where is the leadership? This is an absolute sell out. This bogus plan gives deep-pocketed polluters even more loopholes. And what do we, the public, get? More gross, slimy algae in the water.”
Earthjustice said the plan was developed in a shady backroom deal without public input, and pointed out that a federal court has to review the plan under the terms of an earlier settlement agreement. Continue reading

Aquatic diversity diminishes quickly
By Summit Voice
FRISCO — Streams are much more sensitive to development impacts than previously believed, according to a new U.S. Geological Survey study. The research shows that loss of sensitive species in streams starts at the initial stages of urban development. For example, by the time urban development had approached 20 percent in watersheds in the New England area, the aquatic invertebrate community had undergone a change in species composition of about 25 percent.
