Field Trips and Workshops

2016 Schedule

Field trips arranged by Martha McLaud Tonucci, CBS Field Trip Chair

CBS Field Trips are open to anyone with an interest in learning more about Connecticut’s Native and Naturalized Plants.  This year for the first time we have labeled a few trips as “kid 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 ok to bring them if you think they might be interested.

April 16, Saturday, 10 AM

Meriden, Giuffrida / Lamentation Park

Should we have a late cold spring, this trip may be postponed until the following weekend, 4/24. If in doubt, call the leader a day or two prior to 4/16 at 802-318-1600.

Lamentation Mountain is a 700’ trap rock mountain in Meriden on the Metacomet Ridge.  The top of the mountain has many scenic vistas, which are relatively easy to reach, with about a 400’ gradual rise in elevation, but not a difficult walk.  Additionally, the area has many unique microclimates and rare plant communities.  It sits beside Crescent Lake and borders Guiffrida Park. This will be an early spring trip to see many ephemerals in bloom: Dicentra cucullaria, Micranthes virginiensis, Sanguinaria canadensis, Claytonia virginica, Asarum canadense and Erythronium americanum.  A large area at the end of the reservoir of Anemone americana  always puts on a good show.  We’ll see many other species on the walk down to this patch, and may explore further up the mountain as well. This will be an all-day trip, stopping for lunch on the trail. A half-day trip is optional.



Travel I-91 either north or south. Take Exit 20 and proceed west (left off exit from north or left, then right from the south) onto Country Club Road.  The Park entrance is on the right.  Parking areas are readily available at the Park.  Trails start at the Crescent Lake parking lot. Giuffrida Park, 500 Westfield Road, Meriden, CT  (41.556448°, -72.763941°)

Pachaug State Forest by Wyassup Lake, North Stonington, CT

This is a joint trip with the Rhode Island Wild Plant Society.  Pachaug State Forest is a massive 27,000 acres, and the portion north and west of Wyassup Lake includes a series of hills, ridges and wetlands.  This is a two-part hike, with the second part optional.  The first part is a one-way hike of 2.7 miles lasting about 3 hours.  We’ll hike Cossaduck Hill with a hickory-hop hornbeam forest. Heading downhill, we’ll cross Yawbucs Brook as it flows through a dark, hemlock ravine.  The ravine is broad and lush with ferns and mosses.  After passing a beaver pond and its surrounding meadows, we’ll come to a park-like grove of sugar maples underlain with Christmas ferns, blue cohosh, and hepatica.   The second part is a 1.5 mile loop north of Wyassup Lake lasting 1-2 hours to a series of steep ridges.  We’ll explore the flatlands between them, where rich, fertile soil has built up and flowing streams keep it watered.  Here among the sugar maple, tulip and ash trees you can find herb Robert, red elderberry, maidenhair spleenwort, blunt-lobed grapefern, cut-leaved grapefern, and more cohosh.  Expectations are high for a beautiful display of spring wildflowers. Bring a drink and snack, and wear your comfortable hiking shoes.  Most of our time will be on well-used trails with a couple small hills; moderate difficulty.


From the west: In North Stonington, from Route 2 (Norwich-Westerly Rd), turn east onto Ryder Rd. Go 1.6 miles and turn left (northwest) onto Wyassup Rd. Go 2.1 miles and turn left (northwest) onto Wyassup Lake Rd. Go almost 0.7 miles and turn right into the boat ramp parking lot.  This parking lot is on the west shore of the lake. Map here:

Connecticut Bioblitz: East Hartford, Two Rivers Magnet Middle School

This is a 24-hour inventory with command central at Two Rivers Magnet Middle School, 337 East River Drive, East Hartford, a wonderful facility on the banks of the Connecticut and Hockanum Rivers. The goal is to identify as many Connecticut species as possible: plants, insects, amphibians, reptiles, birds, invertebrates, etc. This year’s BioBlitz in East Hartford responds to the call from the National Geographic Society and National Park Service for every state to run a BioBlitz in 2016, in celebration of the Park Service’s 100th anniversary.More than 100 scientists will begin the species survey on Friday at Great River Park, and will canvass habitats found within a four-mile radius of the Two Rivers Magnet School. Surveyors will be sampling the Connecticut and Hockanum rivers, floodplains, forests, freshwater ponds, open fields, as well as more human-dominated and developed areas, and are hoping to catalogue more than 1,500 species.

Pound Ridge, NY, Westchester Wilderness Walk (Zofnass Family Preserve)

This is a joint field trip with the Torrey botanical Society. The Westchester Wilderness covers over 150 acres of rocky woods, streams, lakes and wetlands. The trails and land have been assembled through the hard work of Paul Zofnass who offered the first contribution of land and then persuaded surrounding neighbors to also contribute land. The end result is a remarkably beautiful and protected wild wilderness. Wear footwear for use on rocky trails.


Exit 34 on the Merritt Parkway, to Long Ridge Road. Go north 5.4 miles on Long Ridge Road. Take a right onto Upper Shad road. Go about 1/4 mile and park on the pull-off on the left side of Upper Shad near the entrance to the Preserve.

Hampton, Cat Den Swamp

Cat Den Swamp is located in part of the Natchaug State Forest in Hampton CT.  It is about a mile north of the old Hampton reservoir. This sphagnum dominated swamp has wild cranberry, cotton grass, Virginia fern and a wide variety of other wetland and bog habitat species. North of the swamp a pipe line offers a good stretch of xeric community plants and east of it we have a dry upland oak forest so botanizing should be splendid. Turkey vultures and porcupine nest and den in a rocky boulder strewn hillside adjacent to the swamp –this area has not been botanized in years.


Please be on time as we will meet and carpool from James L. Goodwin State Forest Conservation and Education Center, 23 Potter Road, Hampton, CT which is off of RT 6 (about 40 Minutes from Hartford and 8 miles east of Willimantic.) It is about an 8-minute drive from the conservation center to Cat Den Swamp. Directions will be available for latecomers, but be advised that access to Cat Den is via a wood road that is well maintained but higher vehicles will find it easier to navigate.

Branford, Horse Island in the Thimble Islands

This trip is dedicated to the late Penni Sharp, a longtime CBS member, director and field trip chair, and also a well-known naturalist in Connecticut and on Fishers Island. Lauren Brown, today’s trip leader, and Penni visited the Thimble Islands frequently and together authored a treatise about the islands’ vegetation.

Horse Island is one of the Thimble Islands, a granitic archipelago which harbor a distinctive assemblage of species.  Horse is owned by Yale University but is not normally open to the public; all of the other islands, except one, are private.   This trip is of interest not only for seeing coastal vegetation but also for seeing the effects of – and the recovery from - Storm Sandy.  We took this trip a few years ago in June, but September will highlight different species.  Transportation will be on a small ferry boat which only carries 14 people.  You must reserve a space by contacting Lauren Brown at or (203)481-0377. There is a $10 fee per person.


Directions and meeting time will be given to those who register with the trip leader.
