Fall leaves on the lawn might seem like a nuisance, but they actually play an important role for the environment. A new survey from the National Wildlife Federation reveals most people know that leaf layers provide a home to moths and insects, which birds need to survive - and yet, they continue to bag them up and send them to a landfill.

Tim Ifill, director of trees, Pennsylvania Horticultural Society, explained trees are an essential part of the environment.

"They're these living things that are used to this nutrient cycle where, you know - in a forest setting, you can imagine - they drop their leaves on the ground, those leaves slowly decompose, return nutrients to the soil, and then the tree roots will take up those nutrients and use them to grow," he said.

The "Leave the Leaves" survey found more than 70% of people know that fallen leaves and leaf layers are beneficial to wildlife, soil health and biodiversity. But only one in four keeps their leaves on the lawn.

Instead of buying mulch for landscaping, Ifill said he runs over the leaves with a mower, which helps add organic matter to the lawn, and explained chopping up and using leaves also offers the benefit of moisture absorption, in a way that is friendly to the local ecosystem.

"The basis of that food chain, in many cases, is this great insect life," Ifill continued. "And they need that leaf litter to reproduce every year and to overwinter. And if we take that away from them, then they're not going to have any places to overwinter. And we're not going to have that basis of the food chain that every other beneficial animal is going to need to survive."

Ifill said another important part of the ecosystem is for people to put native plants in their yards and gardens, which also helps support wildlife.

David Mizejewski, a naturalist with the National Wildlife Federation, said the lawn still needs to breathe, so leaving it totally covered with a few inches of leaves is too much. It is better to chop them up, and added putting leaves in bags for disposal is not a good idea.

"Bagging them up and sending them to the landfill actually is a really bad thing," he explained. "It really contributes some really nasty greenhouse gases to the atmosphere that are a piece of climate change."

The survey notes around 14% of people toss ten or more bags of leaves into the trash per year. Mizejewski said Pennsylvanians can share their space with a wealth of wildlife if they "leave some leaves" and give them some habitat.

A Virginia group is working out ways to reforest former mines across Appalachia.

The state has several hundred thousand acres of mine land, which was being handled under the Virginia Department of Energy's Abandoned Mine Land Economic Revitalization Program. But other groups feel reforesting mine lands can play a role in reducing global carbon levels.

Diana Dombrowski, carbon research fellow at Appalachian Voices, said this is the kind of project the carbon-offset market can invest in.

"They're interested in projects that not only are maybe more local, to where they're based, but also have an environmental justice perspective," Dombrowski explained. "When it comes to the work of reforesting mine land, we're aware of a need in central Appalachia."

The process begins with reclaiming the mine land, which could cost from $7.5 billion to almost $10 billion. But the carbon offset market made $277 billion last year, so it sounds possible. There also are other options available. The Bipartisan Infrastructure Law provides almost $113 billion, appropriated for Virginia's Abandoned Mine Reclamation Fund.

Reforesting former mining areas can help Virginia achieve its climate goals. The projects can add to resilience against storms for communities, and help keep air and soil healthy.

Dombrowski noted other challenges could come up, such as how to identify the best sites for reforesting projects.

"Designing a project that can plan for the most carbon sequestration," Dombrowski suggested. "Where you pick the best land versus a project where you are maybe running over an average, that maybe people will see in the public at large."

Since the work is in the earliest phases, other challenges could arise. Dombrowski pointed out one priority is to focus on environmental justice. She added if any projects turn a profit, the funds will be reinvested into the workforce or materials to keep the work going.

Wildlife advocates are pushing back on a bill in Congress which would remove federal wilderness protections from some Montana land.

There are currently 44 Wilderness Study Areas, making up a million acres of Montana's wildest prairies, river breaks, deep forests and mountain peaks in all corners of the state. Experts agreed they provide unparalleled wildlife habitat, clean air and water.

But Senate Bill 2216, sponsored by Sen. Steve Daines, R-Mont., would remove 100,000 acres from the study areas, including Hoodoo Mountain, Wales Creek and the Middle Fork of the Judith River.

Gayle Joslin, a retired wildlife biologist for the state of Montana, called it a move in the wrong direction.

"These areas would be released to mining, to timber harvest, to recreational development," Joslin pointed out.

A 2022 voter survey found only 6% of Montanans support eliminating protections from the study areas. Daines and other supporters of what's been dubbed the "Montana Sportsmen Conservation Act" countered the study areas are "restrictive" and could be better managed to mitigate wildfire risk and increase public access.

The wilderness areas are open to recreational users but not to motorized vehicles, which the bill would change. It is a slimmed-down version of a measure Daines introduced in 2017, which would have removed protections from 500,000 acres but was defeated.

Joslin argued Montana residents are unanimous in their support for public lands and for many reasons, not the least of which is they are disappearing.

"They are simply not making wild country anymore," Joslin stressed. "Every acre we lose is a loss for wildlife and for, really, wildland scenic and spiritual opportunities for people."

Polls also show close to three-quarters of Montanans want to maintain or increase environmental protections and see development as a 'serious threat.' Critics of the bill said Daines sidestepped input from the public and from federal environmental officials. The measure awaits action in the full Senate.

The Arizona Governor's Office of Resilience and industry leaders discussed clean energy investments in the state at Honeywell's facility in Phoenix Monday.

The event highlighted the partnership between the public and private sectors and how federal funds can be leveraged to continue making investments in renewable energy sources across Arizona, made available through the bipartisan infrastructure law and the Inflation Reduction Act.

Blaise Caudill, energy policy adviser to Arizona Gov. Katie Hobbs, contended when Arizona industry thrives, so do Arizona families. "Emerging, advancing and exciting," are some of the words Caudill used to describe Arizona's current clean energy economy.

"A few months back, the governor was able to attend a ribbon cutting in Northern Arizona for a wind farm," Caudill recounted. "What was so unique about this project in particular was that this wind farm was placed on and co-sited with the largest cattle lands in the state. That is truly Arizona."

Caudill argued it is remarkable to see what he called "one of Arizona's initial five C's - being cattle," coexisting alongside efforts to better handle the state's "emerging climate." He added it is an exciting time for the state to continue developing the clean energy economy, and encourages Arizona stakeholders to expand workforce development programs to meet the state's needs.

David Shilliday, vice president and general manager of advanced air mobility for Honeywell, said the company has had a long-standing history with the state of Arizona and currently employs about 10,000 people, adding they are interested in not just today's economy, but the future.

Shilliday contended the state could improve the current infrastructure of clean energy, which requires establishing improved facilities and fostering what he calls the "workforce of the future."

"We're also deeply involved in local universities," Shilliday pointed out. "To ensure that there are opportunities for developing the curricula for what we think the future needs are for a resilient and enduring Arizona economy that leans forward into this clean energy space."

Shilliday added Honeywell has been able to tap into incentives made available by the bipartisan infrastructure law and the Inflation Reduction Act, and invested the resources in what he called clean energy solutions, renewable energy as well as to upgrade their facilities.
