SPRINGFIELD, Ill. — It was just a few years ago that the approved use of a powerful herbicide was expanded to soybeans. Now environmental groups say native trees in Illinois are becoming collateral damage.

In the past, Dicamba was primarily used to clear weeds from fields prior to planting, and new formulations claim to have lower potential to drift. However, retired Illinois State Biologist Martin Kemper said there have been an unprecedented number of reports of Dicamba damaging susceptible crops over the past several years in Illinois.

He said just as concerning is the parallel rise in injuries to dogwoods, oaks, sycamore and other native trees and plants characteristic of exposure to herbicides such as 2,4-d and Dicamba.

"We are seeing a serious decline in the health of many trees and we've crossed the threshold of mortality for some,” Kemper said. “Trees take a long time to grow. Many of the oak trees that are being injured are keystone species. They provide acorns for wildlife hard mast. Those are very important food sources."

A year ago, the Environmental Protection Agency approved the use of Dicamba on soybeans and cotton for two more years, but required additional restrictions for application and for chemical manufacturers to study off-site movement of the herbicide during the growing season. Kemper argued much more research is needed on what the use of the herbicide could mean for the health of crucial ecosystems and wildlife in Illinois.

Kim Erndt-Pitcher is Habitat and Agricultural Program Specialist for the Prairie Rivers Network, which has a voluntary Tree and Plant Health monitoring program in Illinois to identify symptoms of herbicide injuries. She said they've documented more than 100 cases of off-target herbicide damage to native trees, as well as wildflowers and food crops.

"Everyone concerned about this issue wants to see a high level of coordination and information-sharing as well as a lot of research that is really and truly looking into the aspect of volatilization and the long-term and short-term ecological impact of these exposures,” Erndt-Pitcher said.

Instead of relying primarily on herbicides for weed control, Erndt-Pitcher encourages the diversification of cropping systems and the use of cover crops to suppress weeds, build soil health, protect the environment and reduce the use of toxic chemicals.

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.

April is Earth Month, and North Carolina's climate justice groups are addressing the crucial roles of air, land, water and health in protecting the environment.

CleanAIRE NC and Sol Nation are working together on an Earth Day event to raise awareness about the environmental challenges confronting communities across the state.

Madison Fragnito, partnership manager for CleanAIRE NC, said they are taking a holistic approach and planning STEM activities, with a focus on vital areas like transportation, energy and land conservation.

"We're going to have a lot of activities that focus on plants, conserving land, air quality," Fragnito outlined. "We're going to have some activities related to environmental justice and storytelling, as well as recycling and how you can take everyday actions in your life to improve your commitment to sustainability."

The urgency of addressing these issues is underscored by the state health department, which reports concerning trends from rising temperatures and sea levels to deteriorating air quality and weather extremes due to climate change.

The Earth Day event is on April 20, at the Charlotte Museum of History, from noon to 4 p.m. ET.

Fragnito explained the event also aims to raise awareness about the organizations and the work being done to combat pollution and other environmental concerns. She added in the evening, they will show two short films highlighting environmental justice issues.

"There's kind of a strong community-building aspect," Fragnito pointed out. "Watching the film together, building that sense of community among attendees, and fostering connections and solidarity. Storytelling builds allyship, and it's intended to create an educational and guided dialogue space."

The screening is at the Charlotte Museum of History from 6 p.m. to 8 p.m. ET.

Fragnito emphasized the Earth Day celebration should inspire positive change and show more people how they can engage with groups and take action to protect and preserve North Carolina's natural resources.
