MADISON, Wis. -- Wisconsin is among the top ten states for ethanol production, with nine plants pumping out more than 500 million gallons of ethanol each year. But a new study shows a strong tie between ethanol production and the destruction of wildlife habitat.

Environmental Protection Agency rules say wildlife habitat should not be converted to crop production. But study coauthor Ben Larson, senior manager of forestry and bioenergy at the National Wildlife Federation, said the EPA has been taking shortcuts and not enforcing that rule. He said wildlife habitat near ethanol plants is being turned into land for crop production.

"Rather than actually requiring that ethanol plants check where their feedstocks were coming from, EPA said they would just look at a national level, and assume that none of the feedstocks were coming from recently converted land,” Larson said.

The study shows this assumption is faulty, and shows a clear connection between corn ethanol production and habitat destruction.

A University of Wisconsin Madison study showed that millions of acres of wildlife habitat nationwide have been converted to crop production - most of it planted with corn for ethanol. Study coauthor Chris Wright, a complex systems analyst with the Natural Resources Research Institute, said that land was habitat for ducks, butterflies, grassland birds, and other species. But there's another impact.

"Those lands play an important role in terms of preventing excessive runoff, erosion control; they also actually absorb a lot of carbon from the atmosphere,” Wright said. "So, they have a positive benefit in terms of greenhouse gas reduction."

Larson said the study points to the need for the EPA to rethink how it implements the Renewable Fuel Standard, and to enforce the rule about ethanol plants and corn use.

"Mind you, we're talking about millions of acres - it's not like we're talking about minute areas of land,” he said. "But on a national scale, even millions of acres are relatively small. But for the species that rely on grasslands and wetlands, this is a really major impact, because we've been losing grasslands and wetlands for a long, long time."

The National Wildlife Federation has said it wants to work with the EPA and Congress on strong policies that protect wildlife habitat and water quality, while still promoting sustainable fuels to reduce American dependence on foreign oil.

Environmental advocates are urging Washington state lawmakers to require cargo ships to plug in while in port.

The Port of Seattle will require all cruise ships to use shore power by 2027, but cargo ships face no such requirement. One ship idling for 40 hours emits 30 tons of carbon dioxide and sends 22 pounds of toxic soot into the air, which can harm port workers and adjacent neighborhoods.

Teresa Bui, climate policy director for the group Pacific Environment, said the sheer volume at regional ports requires action.

"The Northwest Seaport Alliance saw visits from 1,700 cargo vessels in 2023," Bui pointed out. "While the port is vital to the state economy, there is both a climate and a public health imperative to transition away from diesel and require these ships to plug in."

A 2023 study found diesel exhaust contributes more than 80% of the cancer risk from toxic air pollutants in the Seattle-Tacoma area.

Legislation to require shore power was introduced in the state House in January but did not make it out of committee. The legislation would apply to any terminal with more than 20 vessel visits per year. State lawmakers have committed more than $50 million toward port electrification.

With the third-largest container ship complex on the West Coast, Bui anticipates strong job creation.

"The additional benefit of requiring ships to plug in is there's job growth potential," Bui emphasized. "The TOTE terminal created 55 local jobs. IBEW supported this measure when it was introduced in the legislature."

A Maritime Administration estimate anticipates 100% shore power at the Port of Seattle would create hundreds of jobs over 30 years.

Environmental and wildlife conservation in Montana took hits during this year's state legislative session, including vetoes from the governor on bills that received bipartisan support.

Among bills Gov. Greg Gianforte vetoed was House Bill 477, which would have phased out some single-use Styrofoam food containers in favor of those made from Montana agricultural byproducts.

The bill's sponsor, Rep. Marilyn Marler, D-Missoula, called it "discouraging" when such a bipartisan effort is vetoed.

"Because it seems to me he did not listen to a wide variety of people, even in his own party," she said. "I think that with this particular bill, it just didn't send the right message about what our values are."

Tourism and recreation are important and growing industries in the state, and as Marler put it, "People don't come here to see trash."

Constituents can see how their lawmakers voted on conservation this session on the Montana Conservation Voters 2025 legislative scorecard.

Marler also voiced concern about weakening the Montana Environmental Policy Act, which was designed to uphold Montanans' constitutional right to a clean environment. While there was a win for habitat funding, Marler added she is seeing continued privatization of wildlife.

"It was not a great session for conservation and it was not a great session for Montana hunters," she explained. "It is becoming very hard to keep commercialization of wildlife off the books."

In renewable energy news, Gianforte vetoed the Montana Solar Shares Act, which would allow Montanans to buy shares in an energy-generating solar array. But a veto override poll for lawmakers is currently underway by mail.

Conservationists are celebrating the protection of five miles of river frontage along the White Salmon River. The 174-acre site was purchased by The Conservation Fund more than a decade after the removal of Condit Dam. The dam was breached in 2011, draining the former Northwestern Lake. The lakebed makes up much of the acquisition.

Gates Watson, vice president of The Conservation Fund, said the removal restored a 44-mile free-flowing river.

"The dam's presence had an impact on the migration route for fish, including regional salmon populations, and disrupted Yakama Nation's right to fish and gather and hunt along this land, and with this transition that will be restored," he explained.

The land was purchased from PacifiCorp, which operated the hydroelectric dam. The site is located in the ancestral territory of the Yakama Nation. The acquisition will be managed by The Conservation Fund temporarily, before being acquired by Yakama Nation on a permanent basis.

Planning for the long-term restoration brought together PacifiCorp, Yakama Nation, The Conservation Fund and an owners association whose cabins sat near the shores of Northwestern Lake. Cabin owners had been leasing land from PacifiCorp. Site surveys were conducted to establish individual lots so owners could acquire the land under their buildings.

Watson said site planning also included a conservation easement and more.

"The vision for the completed White Salmon Corridor project is five miles of connected riparian habitat and a foot trail along the White Salmon River that is owned and managed by Yakima Nation, restoring opportunities for tribal members to access the river and fish," he continued.

The river is a breeding habitat for steelhead, Chinook and coho salmon, and researchers have found juvenile fish are returning in strong numbers.
