Findings come as EPA edges toward final new clean water rule
By Summit Voice
Geographically isolated wetlands like prairie potholes and desert playas in the Southwest are critical to water quality and also provide many other ecosystem services — even though they may lack the regulatory protections of other wetlands, according to Indiana University researchers.
Continued loss of such wetlands is likely “to cause serious harm to North American waters,” according to John M. Marton, a researcher with the IU Bloomington School of Public and Environmental Affairs.
“Geographically isolated wetlands provide important benefits such as sediment and carbon retention, nutrient transformation and water-quality improvement, all of which are critical for maintaining water quality,” Marton said, discussing the conclusions of a new article appearing in BioScience.

Detailed mapping can help plan climate change adaptation
FRISCO — Huge wildfires have driven the conversion of Alaska forests to grass- and shrublands, and the state’s perennial ice and snow fields, as well as its vast wetlands are also shrinking, according to the U.S. Geological Survey.
The changing face of Alaska is revealed in a new land-cover data set, which provides detailed information useful to land use planners and decision-makers. Continue reading

Huge swaths of Colorado wetlands, streams at risk of degradation
By Bob Berwyn
FRISCO — You may not know it as you speed down I-70 from the Eisenhower Tunnel toward Summit County, but a small stream that runs parallel the freeway, just a few hundred yards away, is the main source of drinking water for the town of Dillon.
Straight Creek’s waters gather up between the craggy peaks high above the tunnel, starting from droplets at the edge of a melting snowdrift, to mossy rivulets and roaring cascades amidst granite boulders. Keeping that water pure is important, not only for Dillon residents, but for thousands of visitors staying at local lodges, resorts and campgrounds.
But some of the smallest streams, like the headwaters of Straight Creek, don’t flow year-round, and that has put them at focal point of a long-running debate about the extent of federal clean water rules. The discussion was center stage today during a rare joint hearing of the House Transportation and the Senate Environment and Public Works Committee, where the new GOP majority grilled top EPA administrators about the proposed Clean Waters of the U.S. Rule.

‘Death by a thousand cuts’
FRISCO — Invasive wetlands species are likely to get a boost from climate change, resulting in long-term threats to key native ecosystems, according to new research from Duke University.
“Changing surface-water temperatures, rainfall patterns and river flows will likely give Japanese knotweed, hydrilla, honeysuckle, privet and other noxious invasive species an edge over less adaptable native species,” said Neal E. Flanagan, visiting assistant professor at the Duke Wetland Center, who led the research. Continue reading

Vertical landscape, to emphasize the deep reflections in the pond. This is an unfiltered, unedited shot straight out of the iPhone.
FRISCO — It’s probably no secret, but not all the images in this ongoing series are morning shots (although many are). But today’s sunrise was so cool that I just decided to post a set showing some different flavors of the same scene, with all the shots taken within a half hour and all within a mile of Summit Voice headquarters in Frisco. If the rest of the day is as good as the sunrise, well, it should be pretty spectacular! Continue reading

More money, less red tape would help, experts say
FRISCO — Critical restoration work in the Florida Everglades is lagging well behind where it should be, with government red tape chronic funding shortages blocking the implementation of plans that are already on the books.
A new report says that local, state and federal entities working on long-term restoration of the Everglades ecosystem timely green lights for projects, enough money and some creative policy making to make it all happen. The impacts of climate change — especially sea-level rise — provide a stimulus to accelerate restoration efforts, the report adds.
The report is a congressionally mandated update to the 2011 Central Everglades Planning Project, which outlines ways to renew needed flows in the central Everglades. Continue reading

FRISCO — Conservation biologists in the San Francisco bay area say they’re facing a conundrum, as they try to remove an invasive salt marsh grass while recovering an endangered bird that has come to rely on the non-native plant.
In a study published last month in the journal Science, researchers at the University of California, Davis said that an all-out push to eradicate the marsh cordgrass could hamper efforts to recover the clapper rail, a bird on the brink because of urban development and loss of wetlands.
Their results showed that, rather than moving as fast as possible with eradication and restoration, the best approach is to slow down the eradication of the invasive species until restoration or natural recovery of the system provides appropriate habitat for the endangered species.
Scientists in the southwestern U.S. have faced similar issues as they try to remove invasive tamarisk, which has come to provide habitat for rare southwestern willow flycatchers. Continue reading
