National assessment helps pinpoint conservation issues
The health of American wetlands — at least what’s left of them — in the U.S. is a 50-50 proposition, according to the EPA, which this week released a first-ever national assessment of wetlands conditions, part of a national aquatic resource survey.
Wetlands, once maligned as no-good swamps, are critical for ecosystem health, water quality and flood attenuation, but development and agriculture have chipped away at the waterlogged areas for decades, leaving many degraded.
The UK wants to beef up protection and restoration of peatlands under a new government-backed code that could slash carbon dioxide emissions by 220 million tons and protect rare wildlife at the same time.
The Peatland Code was unveiled at the World Forum for Natural Capital in Edinburgh on November 23 following a successful two-year trial, which has seen businesses fund peatland restoration projects in southwest England, the Lake District and Wales.
The Code is based on research by academics at Birmingham City University and the University of Leeds which revealed that sustainable business investment could reverse the degradation of peatlands and significantly cut greenhouse gas emissions.

More research showing the cascading ecosystem impacts of climate change
FRISCO — Plovers, grouse and other bird species will suffer as global warming changes the hydrology of the UK’s far-reaching blanket bogs, scientists warned after developing a model that shows how climate change will play out in those wetland ecosystems.
The University of York researchers also warmed that the changes could also put drinking water supplies at risk. Warmer temperatures will lead to peat decomposition and altered rainfall patterns, including summer droughts, which could drastically affecting the blanket bog hydrology.
Conservation groups say new rule has too many pollution loopholes
FRISCO — There will be yet more legal wrangling over a new federal clean water rule, as conservation groups said last week they will sue to plug some loopholes that could open the door for more pollution in wetlands and streams.
U.S. Chamber of Commerce leads effort to overturn Waters of the U.S. rule
By Bob Berwyn
FRISCO — A new federal wetlands rule that helps protect water quality and important wildlife habitat will face a federal court challenge from groups representing some of the country’s biggest polluters.
Big loopholes for industry, farms will continue to threaten water quality
FRISCO — After years of wrangling, the EPA has finalized a new rule intended to define which streams are covered under the Clean Water Act. The debate goes back more than a decade to a pair of court rulings that called into question whether smaller tributaries and seasonal streams are subject to federal regulations.
‘Many people would say, what’s the big deal if we drain this small area? But these smaller wetlands are integral …’
FRISCO — A new study by researchers at Waterloo University supports the EPA’s proposed new rule for protecting discontinuous wetlands by showing that those smaller marshy patches function best as a group.
Interconnected pockets of wetlands form a landscape mosaic which provide unique habitat and safe breeding grounds for species such as salamanders and migratory birds. Many traditional wetlands conservation projects tend to overlook that “edge” function and mistakenly focus on preserving only total wetland area, with no consideration of ecosystem services provided by different wetland types.
