Ecosystems work best when diverse

New research at the Cedar Creek Ecosystem Science Reserve north of the Twin Cities adds to a growing body of evidence that diversity matters in healthy ecosystems.

Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present.

A new University of Minnesota long-term study of plant biodiversity found that each species plays a role in maintaining a productive ecosystem, especially when a long time horizon is considered.

Rivers group: South Kawishiwi among most endangered

River restoration and protection group American Rivers has placed the South Kawishiwi River in the Boundary Waters Canoe Area Wilderness on a list of 10 most endangered rivers in America.

THREAT: Copper and nickel mining

AT RISK: Recreation economy, drinking water, and wilderness

Long winter adding to the challenge of manure storage and disposal. This spill threatens a prized fishing and water trail.

A million gallons of manure broke through a concrete-walled pit in southeastern Minnesota late Sunday night, fouling two trout streams before making its way into the Root River, in a major spill that has compounded widespread manure runoff problems in farming counties.

The spill is the latest incident in what one county official described as “perfect storm” of manure problems around the state.

20,000 gallons of crude oil spill as train derails in Otter Tail Co.

Frozen ground should help keep the oil out of surface water

Authorities say 14 cars of a Canadian Pacific Railroad have derailed in western Minnesota and at least three have spilled or leaked crude oil.

The Otter Tail Sheriff’s Department says the 94-car train was headed south near Parkers Prairie Wednesday morning when it lost air pressure and went into an emergency braking mode. Fourteen cars derailed at a rural intersection.

Complex clean-up efforts ongoing at site of fatal truck crash into Red Cedar

When a semi-truck slid off of Interstate 94 and into the Red Cedar River near Menomonie, WI, the initial response focused on finding the bodies of two men believed to be in the river. The trucks cargo is now a concern. Nearly 600 bags of Scotts brand fertilizer with a herbicide have dumped into the river. Now crews are in a race against the warming weather to minimize the damage to fish and the river’s ecosystem.

The difficult and dangerous cleanup of chemicals from the Red Cedar River at Menomonie continued Thursday with cleanup crews making significant progress, the state Department of Natural Resources reports.

Jordan Sands mining project delayed near Mankato

Health department seeks potential for groundwater contamination at the site.

Lime Township’s next decision on the Jordan Sands silica sand mining project has been delayed until May after the company asked for 60 extra days to respond to public comments on an environmental study.

Jordan Sands asked for the delay to thoroughly answer questions about the study, CEO Scott Sustacek said.

“We think we can cover all the comments and questions that came up,” he said.

Fifty-two people and agencies submitted more than 130 pages of comments on the study, said Beth Proctor, a 3rd Avenue resident who lives near the proposed mine.

1 teaspoon of salt pollutes 5 gals. of water, 365,000 tons used on metro road over winter

“One teaspoon of salt can pollute five gallons of water,” said Brooke Asleson, metro watershed project manager for the Minnesota Pollution Control Agency. At high concentrations, chloride is lethal to fish, bugs and vegetation, she said, but even at lower levels it can harm their ability to reproduce and thrive.

Especially vulnerable, said Asleson, are lakes and streams in the metro area, which uses about 365,000 tons of salt each winter on roads.

“We’re not saying fish are more important than being able to drive safely,” she said. “We have to get around safely in winter. But we also need to protect our water resources.”
