After a series of winter storms pummeled California this winter, thousands of trees across the state lost their grip on the earth and crashed down into power lines, homes, and highways. Sacramento alone lost more than 1,000 trees in less than a week. Stressed by years of drought, pests and extreme weather, urban trees are in trouble.

The U.S. Forest Service estimates that cities are losing some 36 million trees every year, wiped out by development, disease and, increasingly, climate stressors, like drought. In a recent study published in Nature, researchers found that more than half of urban trees in 164 cities around the world were already experiencing temperature and precipitation conditions that were beyond their limits for survival.

"So many of the trees that we've relied upon heavily are falling out of favor now as the climate changes," said Nathan Slack, the urban forest superintendent for the city of Santa Barbara. Conifers, like pines and coastal redwoods, once extensively planted along the coast, are dying in droves, he said. "The intensity of heat [and] the longer periods [without] rainfall really force us, as urban forestry managers, to reimagine what are good street trees."

Trees help keep neighborhoods cool, absorb rain water and clean up air pollution. But in order for them to provide those critical functions they need to survive those same conditions. For many cities, that means reconsidering what species are planted.

Slack said he is looking to trees that typically grow further east, like the paloverde, that do better in warmer, drier conditions. "The trees that survive in the desert are going to be much more useful to us here," he said.

In Sacramento, species like the "Bubba" desert willow are replacing redwoods, said Jessica Sanders, the executive director of the Sacramento Tree Foundation. "It's sad because it's an iconic tree," Sanders said, "but it's not really suited to the Sacramento region's climate at this point."

It's not just California cities that are rethinking their canopies.

In Harrisonburg, Virginia, officials are bringing in willow oak and sweetgum - trees that are more tolerant to heat than many local species - from the coast. In Seattle, they're planting more Pacific madrone and Garry oaks, which stand a better chance of surviving hotter, drier summers.

In Detroit, which was once known as the "City of Trees," for its extensive canopy, officials are planting hardy trees like the Eastern redbud, American witch hazel and White oak that can withstand extreme heat and flooding.

City officials are also expanding species diversity to fend off disease, aiming not to allow any single species to comprise more than 10% of the city's canopy. Detroit lost much of its canopy between the 1950s and 1990s to Dutch elm disease and an invasive beetle called the emerald ash borer. Today almost 40% of the trees that remain are considered "poor quality," said Jenni Shockling, the senior manager of urban forestry in Detroit for American Forests, a nonprofit. "[They] consist of species that are prone to disease and storm damage, cause property and infrastructure damage, and drop heavy amounts of debris."

Preserving urban tree cover can mean the difference between life and death on a heating planet. Extreme heat kills roughly 12,000 people annually already in the United States; experts say that figure could reach 100,000 by century's end. A study published by the Lancet in January found that increasing a 30% increase to a city's tree cover could cut heat-related deaths by a third.

Poorer neighborhoods with large non-white populations tend to have less tree cover and can get up to 20 degrees warmer than wealthier (and greener) neighborhoods, according to several studies. "A map of trees in any city in America is a map of income and a map of race," said Jad Daley, the president and CEO of the nonprofit American Forests.

Cites may soon see some relief. The Inflation Reduction Act, signed into law last year, includes $1.5 billion for the Forest Service's Urban and Community Forestry Program, amounting to a five-fold increase in the program's annual budget.

The funding has the potential to transform urban canopies, according to experts like Daley. But as Slack and other arborists across the country turn to new species to fill their streets, they're running into a new issue: supply.

"Right now there are bottlenecks in the traditional nursery supply line," said Shockling. "Growers tend to favor specific species because they grow well in the nursery or grow quickly, but that doesn't necessarily speak to the species diversity standards that we're trying to adhere to."

American Forests has partnered with the U.S. Forest Service to invest in and develop nurseries across the country to improve the supply chain. "The nurseries need some assurances that what they're growing is going to have market value, and we have the assurance that what we're going to purchase will have a supply," Shockling said.

Those large-scale investments will be crucial to updating the make-up of urban canopies, according to David Teuschler, the chief horticulturist at Devil Mountain, one of California's largest nurseries.

According to Teuschler, even California native trees, like the Coastal Live oak, are struggling in the state's droughts. He'd like to invest more in trees like Mesa oak or Silver oak to sell in Northern California and Swamp mallet or Salt Marsh gum to sell in Southern California, but it can take years to grow trees to a saleable size, and then he has only a limited time to sell those seedlings. Unsold trees are usually composted, burned, or otherwise destroyed.

He needs to know he'll have customers who have a clear eye toward the future.

"You have to remember that there are a lot of old-school people out there that want to plant redwoods," he said. "You want to be the nursery that has these drought-adapted species, but if you can't sell them, it's waste."

One of Devil Mountain's longtime customers is California arborist Dave Muffly, who stocks all his projects with drought-tolerant species.

Muffly first began looking for drought-resistant trees 15 years ago, while leading a project to plant 1,000 trees along a two-mile stretch of highway that runs through East Palo Alto. He wanted evergreens, to block freeway pollution from reaching the low-income community on the other side, and drought-tolerant varieties, but most of the state's nurseries held few options.

Muffly began scouring the Southwest for acorns from hardier species of oaks; with more than 500 species of oak around the world that can breed and create viable hybrids, the trees are particularly likely to evolve traits that can help them survive rapid climate change, Muffly said.

With Teuschler's help, his projects - including a 9,000-tree mega-project around Apple's campus - have served as a proof of concept for cities as they work toward climate-resilient tree canopies.

Through channeling federal funding toward nurseries like Devil Mountain, this kind of holistic system could be replicated around the country to meet each region's unique needs, Muffly said.

"The truth is we don't grow anywhere near enough trees in the United States to spend the money that the government just put out," Muffly said. "So now it's time to build an arsenal of ecology, and the production lines are the new nurseries that will have to be built to grow the trees."

New Mexico farmers finding it more difficult to grow historic crops are taking up conservation techniques to meet the challenge.

Drought, water scarcity, and extreme weather events combine to require growers to adopt new methods and modern tools.

John Idowu, extension agronomist specialist at New Mexico State University, shows farmers how to improve soil health and help control wind erosion. For long term success, he said they need to focus on sustainable, regenerative practices.

"How can I optimize my system and make it more resilient to climate change, to weather changes?" Idowu explained. "Once we have all those things worked out, farmers will tend to stay in business for longer."

Earlier this year, a NOAA satellite captured an image of winds lifting vast amounts of dust and dirt from New Mexico's dry farmlands. Some forecasters compared it to images last seen in the 1930s Dust Bowl.

Plowing agricultural fields annually was a common practice until the Dust Bowl period but in recent decades no-till or low-till farming operations have gained traction.

Bonnie Hopkins Byers, program director for the San Juan County Extension Service, encouraged New Mexico farmers to get a soil analysis and consider adopting the less aggressive approach. She said it could mean they do not need to till every year.

"One of the biggest problems is that people do something because that's the way they've always done it, or because it's the way their parents have done it, or their grandparents," Hopkins Byers acknowledged. "My philosophy has always been if you're going to till something over, till something in."

Intense dust storms known as "haboobs" were originally thought to be confined to Africa's Sudan but are becoming more common in other arid regions such as the Southwest.

Idowu stressed it makes the adoption of regenerative practices more urgent, as topsoil on New Mexico farmland disappears due to drought, land use changes and wind, which he noted has been particularly strong this year.

"The wind has been a major force, especially in the spring, so many days where you couldn't do anything outside because of the wind," Idowu observed. "You have a lot of dust and that means a lot of erosion and that is exactly what you don't like when it comes to crop production."

The New Mexico Healthy Soil Working Group formed to help farmers improve their land and livelihoods.

At Mountain View Holsteins in Bethel, Pennsylvania, owner Jeremy Martin is always working to make his dairy more efficient.

Currently, he has his sights set on a manure solid-liquid separator. He'd like to use the solid portion of his manure as bedding for his 140 cows and the liquid as fertilizer.

But the project is pricey - he expects the equipment alone will run around $100,000. So Martin hopes to defray the cost through grant funding for dairy projects that reduce greenhouse gas emissions. Removing much of the solids from manure reduces the feed for the methane-producing microbes that thrive in the anaerobic conditions of liquid manure.

The approach is just one of many dairy practices now considered "climate-smart" because they could cut production of climate-warming gases.

For Martin, a manure separator wouldn't be possible without a grant.

"Once it's in place and going, I think some of these practices will pay for themselves, but the upfront cost is more than I can justify," he says. "If there's money out there to pay that upfront cost to get started, it makes sense to me to do it."

Across Pennsylvania, dairy farmers are learning more about climate-smart practices and funding opportunities, and weighing whether these changes are really sustainable for their businesses as well as the environment.

The Latest Buzzword

USDA has defined climate-smart agriculture as an approach that reduces or removes greenhouse gas emissions, builds resilience to the changing climate, and sustainably increases incomes and agricultural productivity.

"Before climate-smart was a thing, we called it conservation. We called it stewardship," says Jackie Klippenstein, a senior vice president at Dairy Farmers of America.

Indeed, long before the Food and Agriculture Organization of the United Nations coined the term "climate-smart agriculture" in 2010, Pennsylvania dairy farmers had adopted many of the practices that now fall under the label.

For dairy, climate-smart practices largely include strategies that reduce greenhouse gases emitted from cows, manure or fields. Tried and true conservation practices like cover cropping and reduced tillage count.

So do newer practices like using the feed additive Bovaer to reduce methane production in a cow's rumen, or precision nitrogen management to reduce nitrous oxide emissions from fields.

Paying for Climate-Smart

"Margins are very tight on the dairy farm," says Jayne Sebright, the executive director of the Center for Dairy Excellence, a public-private partnership to strengthen Pennsylvania's dairy industry. "Some of these (climate-smart practices) are good for the climate, but they don't make good economic sense until they're subsidized."

In 2022, the center joined a Penn State-run program called "Climate-smart Agriculture that is profitable, Regenerative, Actionable and Trustworthy" to provide dairy farmers with funds for switching to climate-smart practices.

CARAT was launched with a $25 million USDA Partnerships for Climate-Smart Commodities grant, but the future of the Pennsylvania project is in doubt. In April, USDA canceled the partnership program, suggesting that recipients reapply to a new USDA initiative called Advancing Markets for Producers.

Over 60 dairy farmers across Pennsylvania, including Martin, had already applied and been accepted into the first phase of CARAT. This initial phase was intended to help farmers identify the best climate-smart practices for their operations. In the second phase, farmers would have applied for funding to implement those practices. One farmer was already paid for his project before the USDA canceled the partnership program.

"There are fewer funding sources for climate-smart projects than in the last administration. However, private organizations and other entities are funding climate-smart projects," Sebright says. "Depending on what the practice is, (climate-smart) could also be conservation projects. It could be water quality projects."

Sebright suggests that dairy farmers also look for support through state-level funding, such as Pennsylvania's Resource Enhancement and Protection program, which offers tax credits for implementing practices that benefit farms and protect water quality.

Pennsylvania dairy farmers can also contact their county conservation districts to ask about funding opportunities for climate-smart projects, says Amy Welker, a project manager and grant writer for Pennsylvania-based Jones Harvesting, which operates Maystone Dairy in Newville and Molly Pitcher Milk in Shippensburg.

In the next year, Jones Harvesting plans to install a methane digester and solid-liquid separator at a site near Maystone Dairy. The digester is funded with an Agricultural Innovation Grant from the state and an Environmental Quality Incentives Program grant from USDA, along with private funds.

There's money out there for farmers who implement climate-smart practices, says Welker. But "you can't just look at one source."

Long-Term Payoffs

Ultimately, for climate-smart projects to make economic sense, they must continue paying for themselves long after the initial investment. One major goal of the USDA's Partnerships for Climate-Smart Commodities program was to develop markets where farmers adopting these practices could earn a premium.

Some dairy farmers might see that return in the carbon market. National checkoff organization Dairy Management Inc. and its partners have pledged to shrink the industry's net greenhouse gas production to zero by 2050. There are growing opportunities for companies working toward that goal in the dairy supply chain to pay farmers for their contributions.

Early last year, Texas dairy farmer Jasper DeVos became the first to earn credits through the livestock carbon insetting marketplace. DeVos earned carbon credits by reducing methane emissions with a feed protocol that included the feed additive Rumensin. Dairy Farmers of America then purchased those credits through Athian, a carbon marketplace for the livestock industry.

Increased Efficiency

Even without direct monetary payoff, many farmers who adopt climate-smart practices reap rewards in improved efficiency and productivity.

"When you look at climate-smart, you also have to look at what's farm smart," Sebright says. She suggests that farmers choose practices that benefit their farms, not just the climate.

A farmer might decide to put a cover and flare system on a manure pit, not only because it reduces methane emissions but also because it keeps rainwater out of the pit and reduces the number of times each year the pit must be emptied.

Andy Bollinger of Meadow Spring Farm in Lancaster County has been running a manure separator since 2009. The liquid fertilizes his fields, and a portion of the solids becomes bedding for his cows.

He estimates the system saves him at least $20,000 a year in bedding costs.

"We put a fresh coating of it onto the stalls that our cows lay in every day and scrape the old stuff out," says Bollinger, who is also the vice president of the Professional Dairy Managers of Pennsylvania. "It seems to work quite well, and it saves us from buying other bedding products."

No-till farming is also a cost saver because it reduces field passes with equipment, says James Thiele of Thiele Dairy Farm in Cabot, which has been 100% no-till for at least six years. The practice saves him money on fuel and herbicides.

"You're saving your environment, and you're also saving green," he says.

But Thiele questions whether some other climate-smart practices like methane digesters would be practical for his farm, which has 75 to 80 cows.

"I don't know if it'd be worth it for somebody as small as I am," he says.

"I think over the next few years, we'll rapidly see (climate-smart) tools become more available, and we'll see more organizations like DFA talking to our small to mid-sized farmers to make sure they understand they've got a place in this, they can benefit from it, and the practices and tools are affordable to them as well," Klippenstein says.

Weighing Climate-Smart

Many dairy farmers wonder whether some of the practices championed as climate-smart will really support their businesses.

Donny Bartch of Merrimart Farms in Loysville has adopted environmental practices from cover cropping to a manure management plan.

"I want to protect the environment. I want to keep my nutrients here on the farm and be sustainable for another five generations," Bartch says. "But we have to make sure that we're making the right decisions to keep the business going. And to do some of these (climate-smart) practices, the only way they pencil out is to have those subsidies."

There is also frustration with a system that rewards climate-smart improvements made today without acknowledging the contributions of farmers who were climate-smart before anyone put a name on it.

"You come around and want to start rewarding people for doing these things. You really need to start with the ones that have been doing it for a long time, but that's really not what happens," says Jim Harbach of Schrack Farms in Loganton, whose farm has been no-till for 50 years.

Climate-smart grant money and carbon credits are typically awarded for the implementation of new practices.

"It's just the unfortunate way that all of the policies and regulations were written," Sebright says. "What I would say is, if you do a climate-smart plan, maybe there are practices or things you can do to enhance or support or take what you're doing a step further."

Scientific Measurements on Real Farms

Some dairy farmers also want to know more about how climate-smart practices will affect their farms before jumping in.

Steve Paxton remembers participating in a government program to improve timber over 50 years ago on his family dairy, Irishtown Acres in Grove City. His family members were paid to climb up into their white pines and saw off many of the bottom branches.

The goal was to create a cleaner log. Instead, more sunlight shown through, which caused grape vines to climb up and topple the trees.

"The bottom line is, there was research done, it looked good, but it hadn't had enough time to follow through and see just really what the end results would be," Paxton says.

When Paxton sees estimates of how some practices might reduce greenhouse gases emitted from cows, he wonders how much of that research has been tested on actual dairies.

"I think some of it now is just kind of a textbook estimate of what's happening," he says.

More meaningful data is needed to show how climate-smart practices reduce greenhouse gases on individual dairies, Sebright says.

As part of the CARAT program, Penn State researchers planned to place greenhouse gas sensors on a dozen dairies and test how much greenhouse gas production falls as farmers experiment with different practices. The researchers intended to then use that data to build models that predict how those practices may affect emissions on other farms. They will still measure emissions this spring on one farm that is experimenting with a new approach for spreading manure in fields of feed crops.

"The real goal of (CARAT) is to have research that says, if you put a cover and flare (manure storage system) on a 500-cow dairy, this is how greenhouse gas emissions will change," Sebright says. "Or if you use Bovaer on a 90-cow herd, here's how this will affect greenhouse gas emissions."

Martin of Mountain View Holsteins has his own personal beliefs about where a dairy farmer's responsibilities to the planet begin and end. But from a business perspective, he feels compelled to adopt climate-smart practices because he expects the industry will eventually require them.

"Climate concerns are coming whether I'd like it or not," he says. "So my thought is, I might as well get started on it while there's funding to do it."

Oregon's new state budget cuts funding for programs intended to protect residents from extreme weather and make renewable energy more accessible.

Climate justice advocates said it is a major setback after years of progressive climate policies.

Ben Brint, senior climate program director for the Oregon Environmental Council, is disappointed to lose funding for the Community Renewable Energy Grant Program, which supports a variety of projects tailored to communities, including microgrids and solar storage.

"We felt legislators didn't fund climate resilience programs while fires are raging, people's houses are burning down and the state has already experienced record heat waves in June," Brint pointed out. "Legislators don't see we are in an actual climate emergency and chose inaction."

Brint said the grant program aimed to help low-income, rural and communities of color, those most impacted by climate disasters. Lawmakers attributed the cuts to budget shortfalls and uncertainty over federal funding.

Joel Iboa, executive director of the Oregon Just Transition Alliance, said the Community Resilience Hub program, which creates networks as well as physical places to protect people from extreme cold, heat and smoke also lost funding this session. He argued the hubs are effective because communities design them to meet their unique needs.

"Whether it be a place to plug in your phone or a place to go get diapers or get an air conditioner or whatever your community may need," Iboa outlined. "Depending on what's going on."

A heat pump program for rental housing, aimed at making energy-efficient heating and cooling more affordable, was also cut this session.

Brint added he realizes legislators have to make tough decisions about how to fund health care and housing but emphasized climate change is connected to those issues.

"When we're talking about heat pumps or the C-REP program, we're talking about people's health and livelihoods and saving lives in the face of climate fueled disaster," Brint stressed.

Brint added since climate change is not going away, the movement to push for climate resilience will not either.
