‘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

New study shows need for better monitoring
FRISCO — Wetlands have been pinpointed as one of the largest sources of global methane emissions and new research shows that much more of the potent heat-trapping greenhouse gas will be pumped into the atmosphere as northern wetlands thaw and tropical ones warm, according to a new international study led by a University of Guelph researcher.
The study, published in Global Change Biology, is based on one of the largest-ever analyses of global methane emissions, with more than 20,000 field data measurements collected from 70 sites across arctic, temperate and tropical regions.
The results show the need for improved monitoring of wetlands and human changes to those ecosystems – a timely topic as the Intergovernmental Panel on Climate Change prepares to examine land use impacts on greenhouse gas emissions, according to Prof. Merritt Turetsky, lead author of the new study.

FRISCO — After a snowy start to April, winter finally relaxed its grip late in the month, with warmer days and at least a handful of clear mornings and evenings. Nothing against plentiful snow — I love it — but after months of shooting gleaming white snowscapes, it’s nice to get some color back in the scene, and it feels good to hike around on bare ground. Plus, the first wildflowers are starting to show (pasque flowers along the Ptarmigan Trail), and even though the early displays are modest, all the winter moisture should translate into a brilliant display of blooms the next few months. Click on the photos to see them full size, and check our online gallery at Fine Art America for more Summit County nature and landscape photos. 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
