The Cary Institute’s headquarters, the Tozer Ecosystem Science Building, at dawn.
Cary Institute of Ecosystem Studies is well known in Millbrook and the area surrounding it for its 2,000 acres of nature walks, trails, ferns and plants as well as its many forums and presentations.
Over the past few years, the institute was completely renovated. There are new buildings clad in copper; a courtyard; and progressing nicely, a field of native pollinating plants.
What is most important about Cary, however, is what we don’t see: the work that goes on in labs, in fields and streams, not just in this area but across the world. President Joshua Ginsberg is justly proud that Cary is a force behind much of the research concerning important ecological issues of the day and how that research can impact local, state, federal and international laws and decisions.
It is difficult to prioritize Cary’s research and contributions to science and the environment; all of the projects are important.
Cary was founded in 1983 by Gene Likens, the co-discoverer of acid rain in North America. His research and experiments on precipitation and chemistry in streamwater, carried on in the 1960s at the Hubbard Brook Experimental Forest, became the foundation in shaping environmental legislation. He was an advisor to governors in New York, New Hampshire and Connecticut as well as advisor to a U.S. president and the author of 26 books and more than 600 scientific papers, and was awarded the National Medal of Science by President George W. Bush in 2001
His research strongly influenced the Clean Air Act Amendments of 1990, which greatly expanded federal control of toxic air pollutants. To this day, Cary is known for having the longest running continuous data set on acid rain.
Invasive insects
Cary was instrumental in taking the initiative on researching invasive forest pests that come into the U.S. by various means. The late Cary scientist Gary Lovett perceived the problem of invasive species early on; New York state had the more new invasive pests in their forests than any other — 62 types were discovered in the state. These pests, such as the Asian long-horned beetle, discovered in 1996 in Brooklyn, the hemlock woolly adelgid, the emerald ash borer and others, come in through international trade, in lumber and packaging and in live trees and plants.
Scientists sought to strengthen laws regarding the problem, and brought attention to it in highlighting the Agricultural Improvement Act of 2018. Yet the problem persists; just recently in this area, there was a huge problem with the spongy moth and the spotted lanternfly.
Lovett was concerned that not enough was being done and a set of science-based policies were developed, and recommendations made, to block the importation of insects and diseases brought in through international trade systems. Cary scientists, along with others, continues to work with legislators and through partnership to implement Tree-SMART Trade legislation.
A petition was started April 8, 2022, to ask Congress to do something about it. With Lovett and Cary Institute spearheading the petition, it was delivered with over 1,700 signatures to the House and Senate agricultural committees, requesting action be taken in the form of a congressional hearing on these invasive forest pests. On April 4, 2023, a bill was introduced to the Committee on Agriculture, Nutrition and Forestry for action by the Senate.
Foliage fans
Cary scientists understand the importance of trees in ecology. They are studying the impact of forest fires on our ecological system. They conduct research in the U.S. and around the world.
When rain forests below the equator are burned or plundered, we lose all the potential medicines and other undiscovered treasures that they’re hiding.
Trees produce shade, which cools temperatures, and they release water vapor through their leaves. This also helps cool the air. This has an effect on energy costs for the consumer. With three carefully placed trees, a homeowner can save $100-$250 yearly on energy costs, according to the U.S. Department of Energy.
Trees absorb carbon dioxide, releasing the oxygen back into the air and storing the carbon. This helps in reducing the effects of climate change. A mature tree can absorb 48 pounds of carbon dioxide and will provide oxygen in its place.
Animals also benefit from trees, as a source of both shelter and food. Trees produce fruits and nuts, as well as some spices, which we use daily, and provide lumber for building.
Water protection
Water is an element we can’t live without. Emma Rosi, recently retired from Cary, studied how failing wastewater infrastructure plays a part in polluting streams and creating antibiotic-resistant “superbugs.” Rosi’s research showed how prescription and illicit drugs that invade our waterways impact freshwater quality and the aquatic life it should support.
After earning her master’s and doctoral degrees at the University of Georgia, Rosi took on a leading role in the area of freshwater science and researching how emerging contaminants shape these systems. She has served on the U.S. Environmental Protection Agency’s Science Advisory Board.
Disease prediction
Joining the Cary Institute in 2014, Barbara Han got her doctorate in zoology from Oregon State University. Her research involves ecology, global health and computing, all of which she uses to predict outbreaks of new zoonotic diseases, the ones that jump from animals to humans. Of the many cases reported each year — over 1 billion — most can be attributed to zoonotic pathogens.
Han has partnered with collaborators at IBM and NASA on predicting global disease and has also helped the U.S. government and the World Health Organization to apply this specialized research to disease prevention.
Lyme prevention
Richard Ostfeld and Cary Institute partnered with Bard College, the Centers for Disease Control and Prevention, the New York State Department of Health and the Dutchess County Department of Behavioral and Community Health on The Tick Project, a five-year study that began in 2016 to find out if neighborhood-based prevention would have an effect on the amount of cases of Lyme and other tick-borne diseases were contracted.
Simple methods believed to be safe for the environment were used on both humans and pets. Twenty-four neighborhoods were chosen to participate, each consisting of 6 to 10 blocks. They used bait boxes to catch rodents and MET52 insecticide spray. The number of ticks in the yards with bait boxes was reduced to about half the usual number, while the spray had no effect on the number of ticks found. Neither method had an effect on people’s incidences with ticks, but pets’ diseases from tick-borne infection was lower by about 50% in yards using either the traps or the spray.
Cary is a nonprofit. Its website at caryinstitute.org includes forums, scientific papers, biographies and notes on its scientists as well as a place to donate.
Dr. Mark Marshall, an internist at Sharon Hospital, said, “The statistics suggest it’s the worst flu season in 30 years.”
A severe and fast-moving flu season is straining health care systems on both sides of the state line, with Connecticut and New York reporting “very high” levels of respiratory illness activity.
Hospitals, schools and clinics are seeing a surge in influenza cases—a trend now being felt acutely across the Northwest Corner.
“The statistics suggest it’s the worst flu season in 30 years,” said Dr. Mark Marshall, an internist at Sharon Hospital.
According to the U.S. Centers for Disease Control and Prevention, respiratory illness activity is currently classified as “very high” in both Connecticut and New York. Emergency department visits for influenza are very high and increasing, the agency reported, while COVID-19 and respiratory syncytial virus (RSV) activity remain at low levels but are also trending upward.
Health officials say the holiday season created prime conditions for the virus to spread, as people gathered indoors in close quarters and traveled more frequently, increasing exposure and transmission.
Hospitals, schools, nursing homes and primary care providers across the Northwest Corner are also reporting unusually high flu volumes.
Dr. Sarah Humphreys, chief medical officer at Community Health and Wellness Center in North Canaan, said influenza has dominated patient visits since the holidays.
“We’re seeing a ton of influenza. People are coming in with body aches, fever, congestion and gastrointestinal issues,” Humphreys said.
She noted that clinicians are also seeing many infected children, particularly those connected to boarding schools. One private school in the region, she said, shut down prior to winter break after reporting more than 100 flu cases. “At boarding schools it spreads like wildfire.”
At Sharon Hospital, emergency department physicians are reporting a sharp increase in influenza cases, with more patients requiring hospitalizations than in a typical winter.
Between Dec. 1 through Dec. 9, “Our emergency department saw 100 patients who tested positive for influenza A,” said Marshall. Of those patients, he said, 11 required hospitalizations.
The Sharon Hospital physician said clinicians have seen an uptick in flu cases since the COVID-19 pandemic eased, which he attributed in part to people becoming less vigilant about preventive measures such as staying home when sick, masking when appropriate and hand hygiene.
He also noted that a mutated strain of influenza A, H3N2 subclade K, which is associated with more severe illness, particularly among older adults and individuals with preexisting health issues, is contributing to higher hospitalization rates.
That local experience mirrors what health officials are reporting across New York.
The New York State Department of Health announced Jan. 2 that the state recorded the highest number of flu-related hospitalizations ever reported in a single week.
“We are having a more severe flu season than prior years,” State Health Commissioner Dr. James McDonald said in a statement. “Almost 12,000 more people were admitted to a hospital during this most recent seven-day period compared to the prior week.”
The department’s most recent data shows a total of 4,546 flu-related hospitalizations statewide, nearly 1,000 more than the previous week.
Marshall said the impacts of the flu season extend beyond Sharon Hospital and the Northwest Corner, with mounting pressure within the broader Nuvance/Northwell health network, underscoring the pace at which the virus continues to spread.
He described what clinicians refer to as “surging,” a rapid influx of patients arriving with respiratory illness, many of whom require hospitalization, which leads to backups as patients wait in emergency departments for inpatient beds.
“We’re seeing a little of that in Sharon, but at Vassar, they are seeing severe surging,” Marshall said, referring to Vassar Brothers Medical Center, a 349-bed, acute care hospital in Poughkeepsie.
The North Canaan Community Health and Wellness Center has been inundated with flu-infected children in recent weeks, and officials advise families to isolate sick children from older adults and others most at risk for serious illness.
The facility’s chief medical officer emphasized that clinicians continue to recommend the seasonal flu vaccine, despite misinformation suggesting this year’s vaccine is ineffective because it was distributed before the emergence of the H2N3 strain.
“The flu vaccine will decrease the severity of the illness. Unfortunately, it has not stopped spreading,” said Humphreys, who also advised people to protect themselves by wearing a mask in waiting rooms or while moving through health care facilities where the virus may be airborne.
Public and private schools across the region have also been affected by this year’s brutal flu season, particularly in the weeks leading up to the holiday break.
On Dec. 19, the last day before winter break “about 12 percent of the high school’s population, 39 students, were absent,” Nichols noted. Teachers, too, caught the flu, with about 36 staff members falling ill prior to the break.
However, once students returned to class after break, flu cases declined.
“When you don’t have 200 to 300 kids in the same space, you lessen the transmission,” said School Superintendent Melony Brady-Shanley.
“I wouldn’t be shocked if in the next couple of weeks to 10 days, between COVID, RSV and Flu, that the numbers go up.”
Brady-Shanley stressed the importance of keeping children home when sick until they are fever-free, and reinforced basic hygiene.
“If you can get kids to wash their hands three to four times per day, they are less likely to get sick.”
Ed Sheehy and Tom Taylor of Copake, New York, and Karen and Wendy Erickson of Sheffield, Massachusetts, traveled to Salisbury on Saturday to voice their anger with the Trump administration.
SALISBURY — Impassioned residents of the Northwest Corner and adjacent regions in Massachusetts and New York took to the Memorial Green Saturday morning, Jan. 10, to protest the recent killing of Minneapolis resident Renee Nicole Good at the hands of a federal immigration agent.
Good, a 37-year-old mother of three, was shot at close range by an officerwith Immigration and Customs Enforcement, commonly known as ICE, on Wednesday, Jan. 7. She and her wife were participating in a protest opposing the agency’s presence in a Minneapolis neighborhood at the time of the shooting.
The incident sparked protests and vigils nationwide, both in remembrance of Good and in opposition to what demonstrators described as a broader pattern of government overreach.
In Hartford on Thursday evening, Jan. 8, two vehicles that authorities believe were operated by ICE officers drove through a crowd that had gathered in memory of Good. Connecticut Public Radio reported that at least one person had been struck by the vehicles and that police are investigating potential charges.
In Salisbury, the protest unfolded calmly but with a palpable sense of urgency. Just before noon, roughly 160 demonstrators lined Route 44, holding signs and cheering as passing motorists honked their horns.
Organizer Sophia deBoer stood alongside her husband, Lee deBoer, and fellow activists Kathy Voldstad and Amy Lake to greet demonstrators as they arrived. Along with Al Ginouves, the group has organized weekly protests against the Trump administration since April 2025’s nationwide “Hands Off” movement.
“It’s time that people stood up to this lawless administration,” Sophia deBoer said as the crowd waved their signs.
Local immigrants’ rights advocate John Carter echoed that sentiment. “I need to put my body where my soul is,” he said.
Attendees cited a range of emotions for turning out, from anger and fear to cautious optimism
Joan Gardiner said it was “outrage and fear” that brought her to the protest, while Christine Clare said, “Being out here today, this makes me hopeful.”
Calls for justice dominated many of the messages displayed on protesters’ signs. Asked what motivated him to attend, Salisbury resident Louis Tomaino pointed to the words on his sign: “We all saw Renee Good murdered. And we all saw murder excused.”
Area ambulance squad members, along with several first selectmen, attend a Jan. 5 meeting on emergency service providers hosted by Nuvance/Northwell.
FALLS VILLAGE, Conn. — Paramedic coverage in the Northwest Corner is continuing despite concerns raised last month after Sharon Hospital announced it would not renew its long-standing sponsorship agreement with Northern Dutchess Paramedics.
Northern Dutchess Paramedics (NDP), which has provided advanced life support services in the region for decades, is still responding to calls and will now operate alongside a hospital-based paramedic service being developed by Sharon Hospital, officials said at a public meeting Monday, Jan. 5, at the Falls Village Emergency Services Center.
“We haven’t missed a beat; we’re still taking calls,” said Andrea Downs, president of the Falls Village Volunteer Fire Department and an employee of NDP, speaking at the meeting, which was attended by ambulance squad members, first selectmen and representatives of Sharon Hospital.
Sharon Hospital announced Dec. 11 that it would not renew its annual agreement with NDP, ending a 28-year relationship and initially stating that service would cease Jan. 1. Hospital President and CEO Christina McCulloch said the decision was based on compliance concerns tied to the hospital’s role as sponsor.
“Being a sponsor is a big deal,” McCulloch said. “Our concerns were big enough that we couldn’t sign. It was a difficult decision.”
She said the hospital had discussed the issues with NDP representatives and cited unmet state requirements.
Without a sponsoring hospital, NDP could not operate in Connecticut. That issue was resolved when NDP finalized an agreement with Stamford Hospital, allowing it to continue providing services in the Northwest Corner.
At the same time, Sharon Hospital is establishing a hospital-based paramedic service through Nuvance/Northwell, owner of the hospital. Under the current model, the service consists of a single paramedic, who begins the day at New Milford Hospital before traveling to Sharon, prompting concerns from some volunteer ambulance crews about response times while that paramedic is in transit.
Addressing those concerns, hospital officials said while the new paramedic service covers a wide area, so too does NDP, which is based out of Rhinebeck. Some volunteer ambulance crews also said their concerns relate to the transition to two providers, with Sharon Hospital’s service still being built out and not yet fully stationed in Sharon.
Falls Village First Selectman David Barger asked whether more than one paramedic service could operate in the region.
“There could be more than one,” McCulloch said.
Matt Cassavechia, director of emergency services for Sharon Hospital, said Litchfield County Dispatch, which handles all ambulance and fire dispatching for the region, will call whichever paramedic service is available at the time of an emergency.
He acknowledged that the current arrangement could be improved and said the hospital hopes to expand on-site paramedic coverage in Sharon. Doing so would require state approval through a need-for-service application, which Cassavechia said would benefit from letters of support from the community and area first selectmen.
Several volunteer ambulance representatives expressed concern about how changes could affect basic life support services and volunteer operations. Cassavechia said the hospital does not intend to replace volunteer squads.
“We’re not snapping up patients,” he said. “That’s not what we do. We are deliberate and purposeful. We have zero intent of putting volunteers out of business.”
Questions were also raised about possible delays in transferring patients from Sharon Hospital to other facilities.
Gabrielle Tessler, of Copake, writes on a large sheet of paper expressing her opposition to the project as speakers address more than 100 attendees at a community meeting Saturday, Jan. 10, at Copake’s Memorial Park Building.
COPAKE — There was standing room only on Saturday, Jan. 10, when more than 100residents attended a community meeting to hear experts and ask questions about the proposed 42-megawatt Shepherd’s Run solar project that has been given draft approval by New York State.
The parking lot at the Copake Memorial Park Building was filled, and inside Sensible Solar for Rural New York and Arcadian Alliance, two citizen groups, presented a program that included speeches, Q&A, videos and workshop-like setups.
Speakers urged everyone to attend public hearings on the Hecate Energy LLC plan that are scheduled for Wednesday, Jan. 21, and Thursday, Jan. 22, in person at the Copake Town Hall, and in a virtual setting on Tuesday, Jan. 27.
There were representatives from local, state and county government on hand, including from State Sen. Michelle Hinchey’s, D-41, office. Hinchey has expressed concerns about the project. Assemblywoman Didi Barrett, D-106, plans to attend one of the in-person hearings. Sam Hodge, chair of the Columbia County Democratic Party and a potential primary challenger to Barrett, was also present, as were Columbia County Clerk Holly Tanner and Copake Town Supervisor Richard Wolf.
“The vast majority of Copakians don’t want this project,” Wolf said as he began to talk, arguing that the local environment would be damaged, no permanent jobs would be created and the electricity generated would be transmitted downstate.
The state has overridden 16 of the town’s zoning regulations, he said.
“I encourage people to come to the hearings,” he said. “Make your opinions and voices heard.”
Wolf has been frustrated in dealing with the Chicago-based solar developer from the start and asserts that Hecate has “no interest in Copake.”
“I haven’t heard from anybody at Hecate in 20 months,” he said.
Lindsay LeBrecht, a Copake Lake resident, spoke as a member of a panel and questioned why prime farm land is being taken for this so-called solar farm. “It’s not a farm,” she said. “It’s an industrial site.”
One concern cited by the project’s opponents is the adjacency to Taconic Hills Central School in Craryville and the prospect of fire risk. William Murphy, a retired Battalion Chief with the New York City Fire Department, spoke about the fire threats, and said there isn’t enough fire-fighting capacity in the Craryville, Copake and Hillsdale area to adequately respond in the event of a fire. In New York in 2023, he said, there were three large solar facility fires. He also said they are increasing in number and often are unreported.
When he was asked by the school to develop an evacuation plan, he said he declined.
“No plan is fast enough to keep the students safe,” Murphy said.
Animal expert Nick Jacinto, who is based on Long Island and who brought two live owls and a falcon to the community meeting, expressed concern about probable breeding pairs of peregrine falcons and bald eagles that could be threatened by the project.
“Will solar panels become this generation’s DDT,” he said, in a reference to the pesticide that nearly devastated bald eagle populations in the U.S. in the 1960s.
Questions from attendees focused on ways to stop the project, such as banding together to raise funds that could be used to buy out the lease options on the land, or having the town bring a lawsuit. Supervisor Wolf said there is a contingency plan that could bring this into court, but he didn’t believe the lease options can be touched at this point.
There was a lot of community spirit to go around. After the two-hours elapsed, people clustered together to continue discussing the project that has been in the wind in the agricultural hamlet since 2017.
Vicki Sander, a member of Sensible Solar who helped organize the meeting, said she invited Hecate to come. But “I didn’t hear back.”
