JEFFERSON CITY, Mo. -- Wildlife habitat near corn ethanol refineries has been destroyed at a fast pace since a federal law was passed to produce more biofuels. A new study says that across the U.S., 4 million acres of land within a 100 mile radius of ethanol plants have been converted to agricultural use within four years of passing the Renewable Fuel Standard.

Landscape ecologist and study coauthor Chris Wright said the corn belt states have seen much of the habitat destruction.

"It was the ethanol refineries out on the periphery of the industry where we saw significant land-use change,” Wright said.

Congress passed the RFS in 2007 to require blending corn-based ethanol and other renewable fuels with gasoline.

Ben Larson, senior manager of forestry and bioenergy at the National Wildlife Federation and a report coauthor, said the federal law contains language to protect wildlife habitat by not allowing recently converted land to be used for biofuel production. But he said the EPA took a shortcut in implementing the policy: instead, it adds the total of all cropland and looks at whether it increases over time at the national level.

"Well at that national level, you really can't see the concentrated pockets of conversion that we show are happening around ethanol plants,” Larson explained. "It's like if you pull back from the earth far enough, you lose sight of where the impacts are happening."

Another study found 7 million acres of land nationwide had been converted to crop production in the four years following the passage of the RFS, with corn being the most common crop. Larson said this kind of conversion rate has a serious impact on wildlife.

"For the wildlife species that rely on grasslands and wetlands that are being converted to cropland, habitat loss is not an academic issue,” he said. "For instance, grassland birds as a group have suffered the most severe population declines of about any group of species. And that's largely as a result of habitat loss."

The study was conducted by researchers at the University of Minnesota Duluth, University of Wisconsin, and the National Wildlife Federation.

As the Sunshine State grapples with rising temperatures and escalating weather events such as hurricanes, a new study sheds light on the pivotal role of Florida's Wildlife Corridor in mitigating the effects of climate change coupled with a surge of new residents.

The report is trumpeted as a first-of-its-kind study showcasing how the 18 million acres of the Wildlife Corridor, which runs throughout the entire state, ease the worst impact of climate change. It paints a picture of investing in resources supporting cohabitation to be mutually beneficial with nature and the economic growth coming from people who flock to the state to enjoy it.

Colin Polsky, professor and founding director of the School of Environmental, Coastal and Ocean Sustainability at Florida Atlantic University, and the study's lead author, said the corridor benefits the state.

"It's an attempt to welcome the 1,000 people a day approximately who move to Florida, but to do so in a way that allows for the wildlife to continue to thrive," Polsky explained.

About 10 million of the 18 million acres of corridor are permanently conserved. The report calls on state leaders to keep working on investing the remaining 8 million. In March, the governor and Cabinet touted the state's largest investment in decades, a 25,000-acre acquisition within the Caloosahatchee-Big Cypress Corridor.

Joshua Daskin, project manager and director of conservation at the Archbold Biological Station, said since the corridor effort was steering billions of dollars toward land conservation in the state, the report's focus is on showing the science behind it all.

"Climate resilience is one area in which land conservation can help both nature and people," Daskin pointed out. "But no one had assembled the state of the science for all of the ways that climate resilience can be impacted by land conservation."

The report shows 24% of all Florida properties have a more than one in four chance of being affected by flooding in the next 30 years. To combat it, one solution is to keep floodplains undeveloped. The corridors have 10 million acres of floodplain. The report also recommends mixed-use development to minimize habitat fragmentation and keep working lands in production.

Ballots are due back in the Montana Secretary of State's office later this week, as lawmakers decide
whether to override Gov. Greg Gianforte's veto of a high-profile funding bill that would reapportion money from the state's marijuana sales tax.

Gianforte vetoed Senate Bill 442 after the Montana Senate had adjourned last session, which left lawmakers no chance to override it.

It would fund veterans' services, provide permanent property tax relief for vets & Gold Star families, invest in county road maintenance, and support land conservation and habitat management.

Montana Wildlife Federation Executive Director Frank Szollosi said the legislation has received broad support inside and outside the capitol.

"That's why agricultural interests have supported 442," said Szollosi. "Counties have supported 442, and the conservation & sporting communities have supportted 442, and local governments."

Gianforte said in his veto note that using state funds for local responsibilities such as road improvements is a "slippery slope."

A veto override requires the approval of two-thirds of lawmakers. Ballots are due back in the Secretary of State's office on Thursday.

Twenty percent of the sales tax revenue would be used specifically for habitat conservation - but equally important, supporters say, is the money that would be spent to improve veterans' programs and rural infrastructure.

The bill's sponsor, state Sen. Mike Lang - R-Malta - said S.B. 442 would provide services for groups that have not historically shared common interests.

"I just want to bridge the gap," said Lang, "between recreationists and hunters, and private landowners."

Critics of SB 442 have argued the funding distribution formula isn't equitable, while supporters say it directs resources towards those who need them most.

The bill passed the Legislature with 130 of 150 votes in last year's session.

More than $11 million in federal grant money will go to improve land and water conservation in the upper Verde River Watershed and Big Chino Grasslands in north central Arizona.

The grant requires a 50% non-federal match, which The Nature Conservancy Arizona and partners will provide - bringing the total to $23 million.

Kimberly Schonek - Arizona water director for the conservancy - said the Verde River is one of the state's last free-flowing rivers, and calls it a "critical water supply" for not only the Phoenix metro area but for the biodiversity around the river, which starts just north of Prescott.

She said the conservancy in Arizona will be using the money to purchase easements from willing landowners to ensure land preservation and limit groundwater use.

"The landowner will continue to ranch and farm their property into the future," said Schonek, "but it'll restrict that ability for them to develop it, and what that does is keep the water use on the land what it is now."

Schonek said as Arizona thinks about its future, it's important to limit the amount of water use in what she calls a "critical area."

She added that her organization has been enacting conservation easements and other measures along the Verde River since 2012.

Schonek said no landowners are required to participate, but adds many find value in being compensated and reinvesting those funds onto their properties.

Schonek said over the last 20-years, with drought, they've noticed river levels drop - and have also seen land usage around the river change.

She added that while certain areas of the river have less flow, others are now experiencing more water due to the collaborative work the conservancy and agricultural partners have fostered.

"So the future looks good, so long as the community continues to engage, and everybody has a part to play," said Schonek. "And so we are really excited and optimistic to continue partnering with rural communities and agriculture in protecting this river for the future."

Schonek said it is exciting to see this level of investment as they've been working on conservation efforts for decades.

She added that this is by the far the largest amount of money that'll be dedicated to the Verde River.
