More research showing the cascading ecosystem impacts of climate change

Staff Report

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.

Feds face another clean water lawsuit


The federal government is being sued by conservation groups and industry over the new Waters of the U.S. rule.

Conservation groups say new rule has too many pollution loopholes

Staff Report

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.

At issue is the so-called Waters of the U.S. rule finalized by the EPA and the U.S. Army Corps of Engineers in May. That means the feds will be getting sued twice over the rule. Industry groups announced their challenge in mid-July, claiming the new regulations “dramatically expand federal regulatory authority. Continue reading

Polluters sue to block new wetlands regulations

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.

The U.S. Chamber of Commerce, the National Federation of Independent Business,  and the Portland Cement Association last week filed a lawsuit in the U.S. District Court for the Northern District of Oklahoma, seeking to overturn the so-called Waters of the U.S. rule. Continue reading

Environment: New Clean Water Rule finalized, but the fighting is not over

Runoff and rainstorms have combined to keep flows high in the Blue River.

A new EPA rule aims to define which streams and rivers are protected under the Clean Water Act.

Big loopholes for industry, farms will continue to threaten water quality

Staff Report

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.

Yesterday’s announcement probably won’t end the fighting — Republicans in Congress have launched a bitter attack on the rule at the behest of big polluters like industrial farms and factories, and some national conservation groups like the Waterkeeper Alliance say the new rule is too weak, and rolls back protection for some streams that were previously covered.

Small wetlands critical to overall ecosystem functions

‘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.

Environment: Study shows that even ‘isolated’ wetlands are crucial to protecting water quality

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

Staff Report

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
