Field Trips and Workshops

2018 Schedule

Field trips arranged by Gail Reynolds, CBS Field Trip Chair

Field trips are a long-standing tradition of the Connecticut Botanical Society. They provide an opportunity to learn about Connecticut's plants and habitats from some of the area's most knowledgeable botanists -- and an opportunity to share your own knowledge with others. The trips also add to knowledge of the state's flora. On each field trip, we make a list of all plant species we have identified, and this list becomes part of the Society's records.

For the field trips, wear sturdy footwear and bring a lunch. Sunscreen and insect repellant are also recommended. For plant identification, you may want to bring field guide(s), a hand lens, and a small notebook. Familiarity with plant taxonomy is helpful, but not required.

We have labeled a few trips as “family friendly,” based on the location and whether leaders thought inviting children was appropriate.  This designation doesn’t mean that there is special programming for kids, only that it's okay to bring them if you think they might be interested.

Non-members are welcome to join our field trips. No registration is required, unless otherwise stated in the trip description.

April 28, 9:00 AM (Saturday) This trip is full!

Candlewood Hill Wildlife Management Area, Groton

We'll explore the 201-acre wildlife management area owned by the CT DEEP, located in central Groton on historic Candlewood Hill.  Approximately 44 acres of this property comprise an exposed rocky ridge top, with ~2000-2500 pitch pines (Pinus rigida) with co-dominant mountain chestnut oaks (Quercus montana) and an understory of scrub oaks (Q. ilicifolia).  This pitch pine/chestnut oak/scrub oak woodland is considered one of the most threatened terrestrial habitats in Connecticut.  It is also one of the largest if not the largest pitch pine barren in Connecticut.  Most pitch pine barrens are located on sandy or gravelly terrain left by retreating glaciers.  Ridge-top pitch pine barrens are an even rarer subtype of pitch pine barren. At over 300 feet high, this site is one of the highest in Groton, providing winter views of Long Island Sound.

Beneath the scrub oaks there is a nearly unbroken thicket of black huckleberry (Gaylussacia baccata) with unusually sweet berries.  Almost invisibly mixed in with the huckleberry are large numbers of two lesser known shadbushes, the Nantucket shadbush (Amelanchier nantucketensis) and the dwarf shadbush (A. spicata) which will probably be in bloom at the time of the field trip.  Several taller shad bushes are also present. Common lowbush blueberry (Vaccinium angustifolium), hillside blueberry (V. pallidum), eastern spicy-wintergreen (Gaultheria procumbens), and pink lady’s-slipper (Cypripedium acaule) occur beneath the huckleberry.

This site is one of the most spectacular places in the region for hiking and natural history.  Old Granite quarries, hanging wetlands, pristine streams and vernal pools add historic and scientific interest. 

Moderate terrain.  We recommend sturdy, closed walking shoes and long pants to protect against ticks.


From Center Groton (intersection of Rt. 117 with Rt.184) travel east 0.55 mile on Rt. 184.   Park on the slightly inclined grassy shoulder on the right side of the road.

Massacoe State Forest (Great Pond block), Simsbury

From the intersection of Route 167 (West St.) and Route 202 in Simsbury, proceed west on Route 167 (West St.) for 0.2 mile and turn right on Firetown Road. Follow Firetown Road for 0.8 mile and turn left onto Great Pond Road. Follow Great Pond Road for 1.6 miles and turn right into forest. Proceed to parking area.

Burlingame Management Area, Charlestown, RI

We’ll be exploring the north end of Burlingame, between Watchaug Pond and Buckeye Brook Road.  This area is predominantly Mixed Oak/Hickory Forest.  However, the terrain varies from Atlantic White Cedar Swamps to the Red Cedar Rocky Summits, with pockets of fertile richness, as well as sandy Pine Barrens.  Highlights include the state’s largest population of Minuartia glabra (Appalachian sandplant) and four species of Botrychium (moonwort).  If time allows, we’ll hike to the Shumankanuc Mounds on the north side of the road.  Each mound hosts an assortment of unusual plants.

Blue Pond, Rockville Management Area, Hopkinton, RI

During the flood of 2010, the dam that held back Blue Pond ruptured.  To date, it hasn’t been repaired and the result is an expansive grassland or meadow.  The upper reaches of former pond shore are now dry and sandy, and filling in with little bluestem, cranberry, club-mosses, and sundews.  The lower areas form a damp layer of peat where sedges, rushes, and goldenrods are thriving.  Surrounding the pond is a mature forest of oak, hickory, beech and tulip trees.  On our hike through the woods, we’ll stop and look at some of the exposed ledge and the associated plant communities.  Some uncommon species we might encounter include Bartonia iodandra (purple screwstem), Capnoides sempervirens (pink-corydalis), Paronychia canadensis (smooth forked whitlow-wort), Platanthera clavellata (little club-spur bog-orchid), Proserpinaca pectinata (comb-leaved mermaid-weed), Parathelypteris simulata (Massachusetts fern), and Eleocharis tuberculosa (long-tubercled spikesedge).


    1. We will walk 2-3 miles, on and off trails, through forest, over ledge (easy), sunny fields.
    2. We will walk in wet fields/meadows and the shallow edge of the pond.
    3. Boots will enhance your experience, but are not required.

Coastal Plain Ponds, Myles Standish State Forest, Carver, MA

Myles Standish is state forest in Carver and Plymouth Massachusetts, about an hour east of Providence.  It boasts 26 square miles of Pitch Pine/Scrub Oak forest, and dozens of coastal plain ponds, also known as kettle ponds.  These shallow ponds are not fed by surface streams, but by groundwater and precipitation.  Each summer, as water levels drop, the newly exposed shore sprouts a unique assemblage of interesting plants.  We will explore several ponds as well as some of the pitch pine areas.  Wet feet are not likely.

Rocky Top Ridge, Hamden (Mount Carmel Section)

We will walk the traprock ridge crest of York Hill, south west of Sleeping Giant, locally known as Rocky Top, botanizing open summit habitat, with asters, goldenrods and dry-site grasses, as well as exceptionally diverse, mature forest. One can see tree leaves, twigs, and bark  buds, up close, along a trail section through sapling thicket, a former clear-cut.  The 2.6 mile round trip is mostly level, with a a short climb at the start. Pack a lunch; we shall picnic at the overlook above the western cliffs.  We'll end with  an optional  short side trip into  interesting  seepage swamp in adjacent town-owned land at the headwaters on Shepherd Brook.  This was the very first section of the blue trail, built by Reverend Heermance and his family in the early 20th century. We'll pass the remains of  their cabin.  Eighteen  acres of the Rocky Top Ridge were donated to the Hamden Land Trust at the end of 2017 by the developer. This took place after a successful battle to prevent ridge quarrying and condominium development, led by the Macks and their neighbors, assisted by the CT Botanical Society & the Connecticut Forest & Park Association. 


From Route 10, turn west onto Shepherd Ave (across from Aunt Chilada's Restaurant & golf course by Sleeping Giant), head west and then south for 2.2 miles. Turn left (east) onto Rocky Top Road, between two town public works facilities.  After a few hundred feet, park on the right side or before the road narrows at the sharp bend with a pull-off on the left, where the Blue Trail begins, at 64 Rocky Top Road.

East Rock Park summit, New Haven


There’s more to this heavily used area than one would expect.  Walking less than a mile on a paved road in an urban park, we can see a great variety of species, from common to uncommon natives and exotics.  Many state-listed species have been found on East Rock (which is a trap rock ridge) so you never know what we might find.



From I-91 north or south, take Exit 6, Willow Street.  At the end of the ramp, go right.  At first light, turn right onto Mitchell Drive.  Just past the High School, turn right onto Orange Street.  In a block, Orange Street will end and you will be in the park.  Turn left and follow signs for the summit.   As you approach the summit, look for a small Parking sign on the left and park there.  Do not park at the overlook.
