October 1 (Sunday) at 10 AM: Delhaas Woods, Bucks County, PA
Delhaas Woods, a county preserve in Bristol, PA, is probably Pennsylvania's most intact coastal-plain habitat. It is therefore a refuge for numerous plants that are endangered or threatened in the state. It's also home to many showy flowering plants. We will start in a coastal-plain forest, where the rare plants include Quercus phellos (willow oak), Eubotrys racemosa (fetterbush) and Magnolia virginiana (sweet bay). We will then visit a bog and a wet meadow. We can expect to abundant Gentiana saponaria (soapwort gentian) in bloom, as well as other fall flowers (asters, goldenrods, bonesets). We can probably also catch some late flowers on Polygala sanguinea (purple milkwort), Gratiola aurea (golden hedge-hyssop) and Agalinis purpurea (purple gerardia). If time permits, we will visit a nice marsh at the edge of Silver Lake. The trip will involve around two miles of walking on flat ground with good trails. In the wet meadow, you will have the option of staying dry on the trail or walking onto soggy ground to get a closer look at the plants, so choose your footwear accordingly.
Directions: Meet at the parking lot of the Silver Lake Nature Center, 1306 Bath Road, Bristol, PA. From the Pennsylvania Turnpike, take exit 358 and merge onto US-13 south. After 1.3 miles (at a traffic light), turn right onto Bath Road. On Bath Road, drive 0.8 miles, passing Silver Lake Park, then turning right into the Nature Center. From I-95 northbound, take exit 40 for PA 413 North. At the end of the ramp, turn left onto 413 North. After 0.6 miles, turn right onto Ford Road. Proceed 0.3 miles and bear right onto Bath Road. Silver Lake Nature Center will be on your left after 1.3 miles.

January 7 (Sunday) at 10 AM: Winter Botany in Five Mile Woods, Bucks County, PA
Five Mile Woods has been described as straddling the fall line, (the boundary between the coastal plain and the higher, rockier Piedmont), but it is actually entirely in the Piedmont. However, it has Pre-Wisconsin glacial deposits that produce coastal-plain-like soils and vegetation, making the woods a good place to compare piedmont and coastal plain vegetation. We will also work on identifying plants by the material available in winter: seedpods, bark, twig, bud, etc. We'll even encounter some plants that are at their most attractive in winter. The trip will be cancelled if there is heavy snow (more than 6" either on the ground or in the forecast). Any cancellation will be posted on the this page by 7 PM the night before the trip.
Directions: Meet in the parking lot for Five Mile Woods, 1305 Big Oak Road in Morrisville. From Route 1 (NOT business Route 1), take the exit marked Oxford Valley, then turn left onto Oxford Valley Road. After a half mile, turn right onto Big Oak Road, then, after 1 mile, turn right into the preserve driveway, which is marked with a somewhat inconspicuous Five Mile Woods sign. Note that with some navigation systems, you will have to drive a few tenths of a mile past what the system claims to be the destination.
Leaders: Janet Novak, or 215-534-6700 (cell), and Rick Mellon
