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.
Restoration and public use among the key focus areas
FRISCO — After years of planning and public input, U.S. Fish and Wildlife Service officials this week said they’ve completed all the environmental studies and a conservation plan for the San Luis Valley National Wildlife Refuge Complex, in south-central Colorado.
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.

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.
‘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.

Findings come as EPA edges toward final new clean water rule

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.
