2010 FIELD TRIP SCHEDULE

The 2010 field trip schedule is under development. Below are the field trips scheduled so far. The complete schedule will be posted in spring.

January 17 (Sunday)
Botany in the Winter: Nottingham County Park, Chester County, PA

Nottingham Park, encompassing one of the largest of Pennsylvania's State Line Serpentine Barrens, contains one of the richest floras in southeastern Pennsylvania, including a plethora of woody species. Our goals are first to see how many species we can identify at this time of year using identifying marks such as buds, bark, old leaves, and remnant fruiting material, and second to learn how to identify plants when they are not in leaf or flower.
Directions: The Park Headquarters is 150 Park Road, Nottingham, PA 19362. We will meet in the main parking lot.
Leaders: Jack Holt and Janet Ebert, (610) 459-0585, email

March 28 (Sunday)
Spring Break Botany: Nottingham County Park, Chester County, PA

Those who skipped the January 17 trip because of the heavy rain will have another chance. Nottingham Park, encompassing one of the largest of Pennsylvania's State Line Serpentine Barrens, contains one of the richest floras in southeastern Pennsylvania, including a plethora of woody species. Our goals are first to see how many species we can identify at this time of year using identifying marks such as buds, bark, old leaves, and remnant fruiting material, and second to learn how to identify plants when they are not in leaf or flower.
Directions: The Park Headquarters is 150 Park Road, Nottingham, PA 19362. We will meet in the main parking lot.

May 15 (Saturday)
Sussex Branch Trail, Sussex County, NJ

Joint trip with the Torrey Botanical Society
The Sussex Branch Trail near Andover, NJ goes through a variety of limestone-based habitats, including a wetland in an old sinkhole, limestone outcroppings, ponds, and woods. Plant diversity here is high. Our goal is to catch Ranunculus flabellaris, Trillium cernuum, and several other showy species in bloom. The rocky habitats offer Aquilegia canadensis, Arabis lyrata, and several species of Asplenium. Be prepared for soggy ground and for some bushwhacking. Bring lunch.
Directions: Meet in the parking lot of the Twin Lakes boat launch. From the south, take Route 206 north through New Jersey. Get onto interstate 80 west via the ramp on the left. After 1.8 miles, take Exit 25 to continue on Route 206 north toward Newton. After 8 miles (or 1.5 miles after passing through Andover Borough), look for Goodale Road on your right. Follow Goodale Road for about half a mile. Twin Lakes boat launch is on the left.

June 5 (Saturday)
Unionville Barrens, Chester County, PA

Joint field trip with the Muhlenberg Botanical Society
One of Pennsylvania's highest-quality serpentine barrens, the Unionville Barrens finally received long-sought protection in 2008 from Natural Lands Trust as part of the nearly 1,100-acre ChesLen Preserve. The grasslands and blackjack oak-post oak woodlands are remnants of a landscape managed for centuries by American Indians using fire. With fire exclusion, the species-rich serpentine grasslands have shrunk from nearly 60 acres in 1937 to less than 9 acres today. The loss in area has led to species extirpation: 16 state-listed species occur there now but 4 more seen historically are gone. N.L.T. plans to restore and maintain at least 40 acres of oak savanna. A 2005 report, "Protecting the Unionville Barrens" (available at Roger Latham's web site under Publications) describes the site's history, flora and ecology. Appendix A is a survey by Janet Ebert listing 174 vascular plant species. We will see the globally rare serpentine aster (Symphyotrichum depauperatum) and many species in flower or fruit, likely including Carex bicknellii, C. richardsonii, Deschampsia cespitosa, Dichanthelium oligosanthes, D. villosissimum, Helianthemum bicknellii, Packera anonyma, Quercus nigra and Scleria pauciflora. Meet at 10 a.m. Wear footgear suitable for wet walking.

The meeting is based at Buxton School in the heart of Williamstown, down the street from the Clark Art Institute and Williams College. This is a lovely country setting with hiking trails close by.
Program: Field trips, by bus, will include Mt. Greylock, the highest mountain in Massachusetts with its own unique sub-alpine boreal forest and rare plants, and Bartholomew's Cobble, National Natural Landmark, which has one of North America's greatest diversity of fern species and many interesting plants amid the unusual geology of the cobbles. Other trips will depend on the best botanical locations at the time. There will be a variety of evening lectures. Leaders are Pam Weatherbee, Berkshire County Botanist, and Dr. C. Barre Hellquist, Biology Professor Emeritus, Massachusetts College of Liberal Arts.
Housing, meals, and cost: Accommodations are in the school dormitory rooms, though other options are available (see the
