Madison, Wisconsin, Wisconsin Public Radio, July 13, 2026: A potent weedkiller can drift for miles, killing crops and trees. EPA’s new rules may not stop it
About 50 miles southeast of St. Louis, in the small town of Tilden, Illinois, the leaves on the burr oak trees looked odd earlier this spring. Some were curled and cupped around the edges, while others were misshapen. These are classic symptoms of drift from potent herbicides like dicamba or 2,4-D, said Kim Erndt-Pitcher, director of ecological health at Prairie Rivers Network. “Once you see it, you can’t unsee it,” Erndt-Pitcher said. The nonprofit has been documenting pesticide drift in Illinois for nine years. In 2024, the group published their findings, reporting 99.6 percent of the 280 sites surveyed statewide had symptoms of drift damage, and 90 percent of the tree tissue samples collected had herbicide in them. “Year after year, we’re seeing decline in numerous species,” Erndt-Pitcher said. “Some of the most concerning are our oak species because they are keystone species in our hardwood forests and really important to our communities as well.” The Environmental Protection Agency’s decision to issue a new set of regulations for the herbicide dicamba in February brought forth a plethora of concerns from fruit and vegetable producers and environmentalists who worry the rules won’t stop the chemical from drifting…
Minneapolis, Minnesota, Star Tribune, July 13, 2026: To save some trees, one Twin Cities suburb is cutting others down
Bloomington wants to preserve trees — by cutting others down. A $20 million project partially funded by a local sales tax will address erosion and invasive species at Nine Mile Creek, a burbling stream that snakes through dense forest in the heart of the southern suburb. A key goal is restoring the once dominant oak savanna, an ecosystem known for fire-tolerant oak trees that shade grasses and wildflowers. But to foster that fusion of prairie and woods, the city will cut down numerous trees that compete with native oaks, incensing some residents who prize the area’s shade. In dense, developed suburbs like Bloomington, debates about trees can quickly become heated. “Do we want to walk through a shady woodland, or do we want to walk through a really hot savanna?” said Michele Lloyd, a Bloomington resident who co-founded the group Save Our Woods to oppose the tree removal. “We don’t want to just be under the beating sun…”
Kraków, Poland, Notes from Poland, July 13, 2026: Researchers seek to solve mystery of Poland’s “Crooked Forest” before the trees die out
Scientists are seeking to solve the mystery of Poland’s “Crooked Forest” – a set of 90-year-old trees with bizarrely curved trunks – by developing “tree-bending technology” to recreate their unusual growth. The Crooked Forest, located near the town of Gryfino in northwestern Poland, has long intrigued researchers, locals and tourists. Yet the reason why the pine trees have such dramatic C-shaped curves at the bottom of their trunks remains unknown. Efforts to better understand the phenomenon have recently accelerated as some of the trees have been dying out, leading to fears that now is the last chance to unravel the mystery. The researchers and local authorities hope that the new project can create a “Crooked Forest 2.0” for future generations to enjoy. The Crooked Forest is estimated to have been established around 1934 on a plot of land spanning around 1,600 square metres (17,222 square feet), reports the Polish Press Agency’s (PAP) science news service, Nauka w Polsce. It once featured around 400 of the oddly curved trees, though now only around 100 remain. The forest has become a point of curiosity, drawing large numbers of tourists and sparking various theories about how the trees obtained their unusual shape…
Seattle, Washington, Washington Week, July 13, 2026: The PacWest Center Pine Tree Has Died at Age 42
The pine tree on the 25th floor terrace of PacWest Center downtown has died. It was 42 years old. The quirky fixture of the Portland skyline was removed for safety reasons, according to Wyatt Cerny, vice president of real estate at Fountainhead Development, the Fairbanks, Alaska–based company that has owned PacWest Center since October 2025. An exact cause of death was not given, but an arborist evaluated the pine and determined it was “in declining health and no longer viable,” Cerny said. “A new cherry tree has since been planted, and we look forward to it maturing into a new curiosity of the Portland skyline,” Cerny said in an email. A dead tree was spotted on the terrace of 1211 SW 5th Avenue as recently as July 9. The pine tree was planted in 1984, when PacWest was built, and eventually stood about 40 feet tall. Environmental historian Dave Hedberg, author of From Stumptown to Tree Town, had been scoping out the evergreen for the Oregon Heritage Tree Program, but those hopes died with the tree…
Washington, DC., Post, July 12, 2026: A California school district wants trees removed. A community seeks to stop it.
It was at a high school named for the father of environmental preservation, John Muir, that activists chained themselves to trees after their screams did not stop the chainsaws. Every day for weeks the group had taken shifts to scout the campus. They were on alert for the day that Pasadena Unified School District might cut three American sweet gum trees that have grown for decades. This act of defiance is the latest escalation in a conflict over nearly 200 trees that sit in contaminated soil on Pasadena’s public school campuses. Pasadena Unified School District, working with the California Department of Toxic Substances Control has said the trees need to be removed along with the soil before school starts in August. Activists argue that other methods can be used to clean the fire-tainted soil without removing the trees and that many are protected by a local ordinance…
Aeon, July 12, 2026: Lore of the Rings
We were a team of five: Jan, Paul, Jonas, Claudia, and me. Four dendrochronologists and one son of a dendrochronologist. Jan Esper flew in from Germany. Paul Krusic drove his Land Rover from his home in Stockholm down to southern Italy and then on the ferry across to Greece. He had brought his son Jonas, a precocious 12-year-old Viking. Claudia Hartl and I drove in from neighbouring Albania, where we had already spent 10 days sampling. We all met up in Samarina, a small Greek village at the foot of Mount Smolikas, the highest peak in the Pindos mountains. The reason we were there was to core trees called Bosnian pines (Pinus heldreichii), which we suspected could be old. What we didn’t know that morning was quite how old. Nor just how much these trees would tell us about the centuries of events and circumstances they had experienced in their lifetime. Trees hold stories: they are witnesses of time and history. Of course, we can read a tree’s age and local climate from its rings, but in recent years we’ve discovered so much more. Deep inside a tree’s trunk is an archive waiting to be found: tales of planetary shifts, cosmic events, and even turning points in human history. And the oldest trees have seen it all…
Salt Lake City, Utah, Tribune, July 9, 2026: One of Utah’s biggest trees burned in a wildfire. Residents are saying a tearful goodbye.
No one is really certain when the massive tree tucked deep in the Tushar Mountains first took root or who was the first to stumble upon it. It’s also not clear what allowed that specific pine to grow to 123 feet tall. Some estimate the towering ponderosa near the small town of Beaver — where residents affectionately call it “Big Tree” — has been there at least 350 years, making it a century older than the United States. Others guess it has to be at least 150 years old, outliving any one human who might know the answer. “When you’re standing at the base of a living thing that big and that ancient, it’s a humbling feeling,” said Chelsie Rios, who grew up in Beaver. The central Utah community has embraced the tree for generations as a symbol of a slower, more meaningful way of life… And now that it’s gone, the loss is being mourned by many in Beaver like a death in the family…
Phys.org, July 12, 2026: Trees for hotter cities: New approach can bolster community input in meeting targets
Efforts to plant more trees in cities could be boosted thanks to a new tool for planners and community groups, published by an international group of researchers. Residents, policymakers and tree officers in Cardiff, Milton Keynes, Edinburgh, York and Camden worked with academics to develop new advice to grow trees in a way that benefits both people and nature. Trees in urban areas are increasingly recognized as important for tackling climate change, improving biodiversity and supporting health and well-being. They also help cities adapt to rising temperatures, providing shade and reducing exposure to extreme heat. The UK government has a target to increase tree planting to 30,000 hectares per year as part of efforts to tackle climate change and biodiversity loss…
Salem, Illinois, WJBD Radio, July 9, 2026: Large fire break out in large logs at tree-cutting service in Salem early Thursday morning
A fire that is believed to have started from spontaneous combustion in large logs stored outside Top Notch Tree Service on East Main Street in Salem is under control, but is expected to burn out over the next few days. Salem Assistant Fire Chief Bill Fulton says the city used a track hoe to split the burning trees from those not on fire to keep the fire from spreading. He says flames were shooting from the trees upon their arrival. “Found was part of the pile of debris that they bring in form the tree service was on fire towards the very south end. It’s all interconnected, so what we tried to do is put a stop between it and the major part of the pile. It would be hard to get the whole pile completely disposed of and put out.” The fire department was later assisted by Salem Public Works who brought an end loader to the scene to cut a bigger gap between the burning and non-burning trees. The city then pushed together the burning trees so they could be allowed to burn themselves out. Fulton believes he knows the cause of the fire…
Boston, Massachusetts, Globe, July 7, 2026: In the woods of Maine, searching for an answer to a ticking climate bomb
Scientist Kathleen Savage leaned out from the basket of a boom lift, a red safety helmet perched on her head. She sealed a few needle-covered stalks from an Eastern Hemlock tree inside a clear plastic cylinder and pulled out her phone. On the screen, a meter rose and fell as the level of gases inside the cylinder fluctuated. The question she was asking: What were the microscopic bugs on the stalks and leaves doing in there? The answer would provide limited data — just one point, from one portion of a tree in one forest. But looked at another way, it could also buy the planet critical time as the world races to address the climate crisis…
Science Daily, July 8, 2026: Trees keep absorbing carbon long after they stop growing
Trees do not necessarily keep growing for as long as they keep photosynthesizing, according to a new study published in Science Advances. Researchers found that oak trees continue absorbing carbon dioxide well after their annual growth has ended, suggesting forests may store less carbon in wood than many climate models currently predict.
The discovery challenges a long-standing assumption that higher rates of photosynthesis naturally lead to greater tree growth. If trees continue taking in carbon without turning much of it into new wood, less carbon may remain locked away over the long term. Forests play a major role in slowing climate change because trees remove carbon dioxide (CO2) from the atmosphere and store much of it in their trunks, branches, and roots. Scientists have generally expected that rising atmospheric CO2 levels would boost photosynthesis, leading to faster growth and increased long-term carbon storage…
Las Vegas, Nevada, KLAS-TV, July 8, 2026: Summerlin neighbors say officials know why hundreds of mature trees are dead, missing
The bark of the ash tree in front of a Las Vegas post office is unseasonably dry and waning. It’s barely budding, and Summerlin neighbors said elected officials know why, but they want you to see that not much is being done to change the situation. Approximately 200 mature ash trees are dead or missing in the North Summerlin area and many more in Hills Park, after the early implementation of Nevada Assembly Bill 356, passed in 2025, which imposes restrictions on most grass across the valley. The January 2027 deadline is spurring the removal of “nonfunctional grass.” However, it appears that miles of grass removed was essential to the life of hundreds of over 20-year-old trees throughout the Summerlin area. Once the grass was removed around the summer of last year, some in other phases, the trees appeared to decline rapidly…
Plattsburgh, New York, WPTZ-TV, July 8, 2026: Two men fined $35k for cutting down 300+ trees to build illegal mountain bike trail in Stowe
Two Vermont men have agreed to pay $35,000 and remove unauthorized trail features after state officials alleged they illegally built mountain bike trails in Mt. Mansfield State Forest, the Vermont Attorney General’s Office announced. Attorney General Charity Clark said Cyril Brunner and Aaron Rice settled allegations that they unlawfully constructed approximately 8,000 feet of mountain bike trails in the state forest in Stowe between 2016 and 2021. “No one should be treating state land and state forests like their backyard,” the attorney general said Wednesday. An investigation by the Vermont Agency of Natural Resources found the men cut down about 327 trees and permanently altered rocks by drilling holes to anchor wooden trail crossings, according to the settlement. “The investigation was probably done by the Agency of Natural Resources and they referred the case to us,” said Clark. “We get this information about what had happened and then take the steps we need to hold the bad actors accountable for the timber trespass…”
The Economist, July 8, 2026: How the biggest trees survive droughts
Towering over 100 metres above the forest floor, the dipterocarp—named after its winged seeds, which spiral away in the wind—is the tallest tropical tree in the world. For a plant, being tall is an advantage: if your neighbours cannot overshadow you, that leaves you with the lion’s share of the sunlight. But trees need water as well as light, and here being tall presents a problem. The physics of moving liquid through thin channels means that the taller a tree gets, the harder it is to pump water from the soil to the leaves in the crown. Scientists had assumed that would leave big trees, like dipterocarps, more vulnerable than their more diminutive competitors when water was scarce. But in a paper published on July 2nd in Science, a team led by Paulo Bittencourt of Cardiff University have shown that, thanks to some clever evolutionary engineering, that is not true. A tree’s trunk contains a network of tubes known as xylem whose job is to ferry water from the roots to leaves. While many animals pump fluid around their bodies with a heart, trees rely on evaporation to keep the liquids flowing. As water in the leaves escapes into the air, it creates suction in the xylem. That draws more water up to fill the space. That process is aided by the properties of water itself. Water molecules tend to cling to their neighbours, so that as one is drawn up, others follow. The molecules also adhere to the walls of the xylem, helping to counteract the downward pull of gravity…
Portland, Oregon, The Oregonian, July 7, 2026: Portland backs PGE plan to cut hundreds of mature Forest Park trees in what critics call a backroom deal
A controversial transmission project that would cut hundreds of mature trees on about 5 acres of Portland’s beloved Forest Park is likely to move forward under a new agreement between Portland General Electric and the city of Portland. Opponents say the deal could set a precedent for additional utility projects and more environmental damage in the park. The project would require PGE to fell more than 370 of the nearly 700 trees assessed within the project area, primarily Douglas firs. Many Oregon white oaks, bigleaf maples and lower-growing vegetation would remain, the utility said, because they are less likely to conflict with the transmission lines…
Deutsche Welle, July 8, 2026: The Australian tree reshaping the world’s wildfires
Each year, more than 400,000 hikers descend on Galicia for the Camino de Santiago pilgrim walk, crossing misty hills and dense green woodland. But much of the forest surrounding the route is no longer native. Instead of indigenous oak and chestnut, large parts of northwestern Spain are now dominated by eucalyptus. That transformation is not unique to Galicia. Prized by the pulp and timber industries for its rapid growth and profitability, vast monocultures of the Australian tree have been planted in places such as Brazil, Chile, California, India and South Africa. Globally, eucalyptus plantations now cover 22 million hectares across more than 90 countries, and in many regions, they have become a cornerstone of rural economies. But hiding beneath the seemingly tranquil canopies are landscapes vulnerable to extreme wildfires because scientists regard the trees as highly flammable…
Wichita, Kansas, The Wichita Eagle, July 6, 2026: Wichita issues warning after person trims park tree during World Cup watch party
The city of Wichita is warning residents to not trim or cut trees on city property after video began circulating of a partygoer trimming tree branches at Sunday’s World Cup watch party. Monday morning, a Wichita Eagle reporter verified the video by going to the downtown park and noticed branches that had been recently cut and a pile of small limbs set aside on a nearby sidewalk. The video in question said the branches were in the way of the screen at the park showing the Mexico v. England game. “Trees in our parks are public assets that enhance the park experience for all visitors, and any pruning or maintenance is performed by authorized City staff,” city spokesperson Tyler Schiffelbein said. City ordinance strictly prohibits unauthorized cutting or alteration of trees on city property…
Palm Springs, California, KESQ-TV, July 6, 2026: Palm Springs-based nonprofit to oppose city’s proposed palm tree trimming
A Palm Springs-based nonprofit organization focused on protecting local wildlife and wildlife habitats urged the city today to reject a proposal to remove more than 2,000 dry fronds from city-owned palm trees. According to a proposal going before the Palm Springs City Council on Wednesday, city staffers are calling for the removal of dry fronds, otherwise known as skirts, from California fan palms located in pedestrian areas to eliminate potential risks to the community. A skirt can potentially injure pedestrians or arborists when they fall, since skirts can weigh more than 1,000 pounds, according to the staff report. Additionally, roof rats and cockroaches are known to nest in palm tree skirts throughout Southern California, posing health risks since they both can carry serious diseases, according to the report. If the proposed resolution moves forward, the city’s roughly 2,150 California Fan Palms — under the classification of Washingtonia filifera and Washingtonia robusta — will be removed of skirts, fruit pods and trunks over the next four years at a cost of $300,000…
