The Greenwich Tree Conservancy Celebrates its Festive and Fruitful ‘Tree Party’

Greenwich Sentinel / By Anne W. Semmes / May 1, 2026

Since the year 2007 the Town of Greenwich has been graced with a nonprofit effort to enrich, enhance, and add to its trees and forests, “to benefit our health and quality of life.” So read the invitation to the Greenwich Tree Conservancy’s (GTC) annual “Tree Party” benefit held traditionally at the McArdle’s Greenhouse as of last Friday week. And this year the “Tree Party” fell on Arbor Day!

The theme this year was “Flight of the Forest” with some 180 attending ticket holders bringing with their contributions “more trees in our town and enhancing the habitat that lets local and migrating birds sing.” That promise was fulfilled: “You’ll connect with neighbors, who also want to protect our town’s natural heritage and support the vital work of preserving and enhancing our precious tree canopy.”

Colorfully dressed attendees were happily gathered together and surrounded by an aromatic array of extraordinary flowers as GTC Board President Elizabeth Hopley greeted guests. “Happy Arbor Day everyone, delighted to see you all here! Thank you all so much for coming and supporting the Tree Conservancy.” And she thanked James McArdle “and his wonderful team for this always lovely venue.” Her “huge” thanks included such sponsors as

the Peter Malkins, Dave Williams, and U.S. Senator Richard Blumenthal and wife Cynthia Malkin Blumenthal, Bartlett Tree Experts, Sam Bridge Nursery & Gardens, “and Val’s Putnam Wines & Liquors, who generously donated the delicious wines and spirits tonight.”

Our Oldest Trees Draw Crowd, Sense of Stewardship

By Greenwich Sentinel / Featured Article / April 23, 2026

A group of residents stood beneath a towering Japanese white pine on a recent March afternoon, watching as a small team measured its trunk and canopy with practiced precision. The demonstration, part of the Greenwich Tree Conservancy’s Notable Tree Program, drew attendees to the Greenwich Botanical Center.

The gathering focused on something easy to overlook in daily life: the trees that have stood in place long before the town’s roads, homes, and schools were built. These trees, some of them recognized as the largest of their kind in Connecticut, have become markers of both time and stewardship.

Greenwich is well-represented in the database, with 208 trees total, of which 151 are confirmed to be extant. 32 are champion trees and 12 are co-champions, meaning that they were determined to be the largest examples of their kind found in Connecticut. To find out more about the Connecticut Notable Trees project go to: https://oak.conncoll.edu/notabletrees/

The program maintains a database of significant trees across Connecticut, and Greenwich holds a prominent place within it.

Frank Kaputa, co-chair of the statewide Notable Tree Program, led the presentation alongside team members John Kehoe, Marty Aligata, and Kyle Dougherty. Over the course of an hour, the group outlined how trees are identified, measured, and cataloged, and why the effort has grown into a statewide resource.

Tree Tales

By Cheryl Dunson / Greenwich Sentinel

As I write this, it seems that winter’s bitter cold and snowy grip is loosening. Daffodil leaves are pushing through the soil, birdsong can be heard intermittently, and trees are starting to bud. While Greenwich is a beautiful town at all times of year, arguably Greenwich seems at its loveliest in spring with the canopy filled with a lovely array of white, pink, and red flowering trees.

It almost seems miraculous when reflecting on what the trees had to endure this winter. Trees are a marvel in so many ways. It got me thinking about books where trees are a focus that have informed and/or inspired me. And then I wondered about what books may have informed and/or inspired my board and advisory board colleagues at the Greenwich Tree Conservancy. I decided to ask them. Below is an admittedly idiosyncratic list of fiction and non-fiction tree related books that we have enjoyed. We hope you do too!

A New Forest Crisis: The Threat of Beech Leaf Disease in Connecticut

New Canaan Sentinel article by Kate Dzikiewicz

Over the past century, Connecticut’s forests have endured repeated waves of invasive pests and diseases. Dutch elm disease, chestnut blight, and other destructive pathogens have wiped out once-dominant tree species, permanently reshaping the composition and character of our woodlands. Today, our forests face another serious threat: Beech leaf disease.

American beech trees are a foundational species in many Connecticut forest ecosystems and among the most common native trees in our region. Their nuts provide a rich source of protein and fat for wildlife, including squirrels, wild turkey, black bears, and numerous bird and small mammal species. In good health, beech trees can live an extraordinary 300-400 years and when grown in open areas such as parks and yards, their trunks may reach two to three feet in diameter. Connecticut is home to several remarkable specimens, including a magnificent beech in Greenwich Common Park off Greenwich Avenue. This tree is part of the Greenwich Tree Conservancy’s town-wide Arboretum. Arboretum Curator Lisa Beebe found that the trunk measures 14.5 feet in circumference, or over four feet in width!

Unfortunately, beeches in our forests, parks, and backyards are now under grave threat. Since its arrival in Connecticut, beech leaf disease has spread rapidly. Without intervention many of the state’s beech trees could be lost in the coming years, but emerging treatments are offering new hope.

Greenwich Tree Conservancy Elects New Members to Board of Directors

The Greenwich Tree Conservancy is pleased to announce the election of Elizabeth Hopley as President of its Board of Directors.

Ms Hopley’s involvement with the Greenwich Tree Conservancy began in 2018, when she co-chaired the organization’s annual Tree Party.

She joined the Board in 2022 and has since played an active role in initiatives focused on undergrounding utility wires, tree preservation, and town beautification.

A longtime Greenwich resident and RTM member, Hopley is also deeply engaged in numerous regional and national organizations, bringing broad experience and thoughtful leadership to her new role.

The Tree Conservancy also welcomes three newly elected members to its Board of Directors: Matt Popp, John R. Conte III and Betsy Vitton.

Each brings a distinct and valuable skill set to support the organization’s mission.

From Palms to Peaches: What Actually Is a Tree?

The GTC recently explored a deceptively simple question: what is a tree? While scientists often define a tree as a tall, woody plant with a single trunk, the reality is more complicated. Many plants can grow as shrubs or trees depending on conditions, and some familiar “trees,” like palms, bamboo, and bananas, don’t meet the classic biological definition at all.

The confusion extends to taxonomy. Trees aren’t a single biological group; tree-like forms have evolved many times across different plant families. In fact, a peach tree is more closely related to a rose than to an oak.

For the GTC, however, the answer is more practical. Connecticut’s climate naturally limits what can grow here, leaving us with traditionally woody species that thrive locally. Our focus remains simple: planting and protecting the trees best suited to our environment to help create a Greenwich that is greener, healthier, and more beautiful.

Greenwich Kicks Off Tree-Planting and Habitat Restoration at Laddin’s Rock

The GTC is proud to partner with the Town of Greenwich on the first phase of an ambitious habitat restoration and tree-planting project at Laddin’s Rock Sanctuary in Old Greenwich.

Prior to restoration efforts, large sections of the 18-acre sanctuary—featuring natural forest, walking trails and waterways—had become severely degraded by invasive Japanese knotweed. Greenwich Parks & Trees staff successfully removed the knotweed and will continue to monitor and maintain the area in the coming months.

Following the invasive removal, we planted an initial 70 trees throughout the sanctuary, with additional plantings planned for the spring. The trees include a diverse mix of cold-hardy native species commonly found in Connecticut forests, such as American hornbeam, tulip tree and five species of oak.

The Green Infrastructure Upgrade that Will End Blackouts

By Elizabeth Hopley / Column in the Greenwich Sentinel

The day before Thanksgiving, during families’ last minute errands, a construction supply truck snagged the sagging wires along busy East Putnam Avenue, grinding traffic to a halt. Firemen arrived quickly to untangle the mess and divert traffic, but had to leave the wires strewn in the street until the utility company could restring them back to their precarious perch. It’s unknown how many stores and residents lost power, internet, phone, but it begs the question: Isn’t there a better way for utilities to service customers in the 21st century?

This same story plays out countless times across our town and nation: a fragile 19th century system of exposed overhead wires easily derailed by minor mishaps or weather conditions, causing blackouts, lost productivity, and safety issues. Lawrence Berkeley National Lab found that America’s overhead grid costs us $80–$180 billion every year in outages, spoiled food, lost wages, and emergency services.

Now, imagine our town without the unsightly web of overhead wires. Instead of driving past a procession of utility poles leaning under the weight of too many wires, there’s a lush, green canopy of trees, cleaning the air, absorbing storm water runoff and cooling the road in the heat of summer. Meanwhile the underground grid is buried safely along our roads, bringing worry-free reliability to our utilities infrastructure.

. . .

Undergrounding overhead wires and planting trees will deliver four immediate wins: First, blackouts almost disappear and communications like phone and cable become stable and reliable. Second, scenic beauty is restored as trees replace the visual clutter of wires and poles. Third, home values increase by 7–20% in neighborhoods that have underground utilities. And lastly, the cost can be offset by savings in other areas. Outages already cost billions. New drilling technology has slashed undergrounding costs and the outsized costs of maintaining overhead systems are minimized

Trees Take Root at Cos Cob Railroad Station

In early November, the Greenwich Tree Conservancy planted eight new trees at the Cos Cob Railroad Station parking lot, a commuter hub on the New Haven Line of the Metro-North Railroad. Serving residents traveling to New York City and other destinations along the line, the station is one of Greenwich’s primary public transportation centers.

Its parking lots were found to contain substantial unused space suitable for additional trees, including areas where trees once stood but were never replaced after removal.

The Greenwich Tree Conservancy selected the Cos Cob Station parking lot as the latest site in its Parking Parks initiative, which has brought shade and beauty to municipal lots across Greenwich. Unshaded parking lots are major contributors to the urban heat island effect. Air temperatures in full-sun lots can be 4–8°F higher, while the surface temperature of unshaded asphalt can soar nearly 40°F hotter than shaded surfaces. Inside unshaded parked cars, temperatures can spike by as much as 50°F when compared to cars parked under trees.

The eight newly planted trees will help reduce these extreme temperature swings and also improve stormwater management, which is an important benefit for an area that experiences frequent flooding during severe storms. Trees are also important for softening the appearance of parking lots, which can otherwise prove unsightly in suburban neighborhoods.

This planting emphasized native species and trees well-suited to the demanding conditions typical of parking lots. The selected varieties include Kentucky coffee tree, scarlet oak, swamp white oak, and Shumard oak.
