Join the New England Wild Flower Society on a hike botanizing two different communities formed by two dramatic glacial features:  a double drumlin and a kettlehole, owned by The Trustees of Reservations. We visit Weir Hill Reservation with Frances Clark and walk through 80 acres of field and woodland under fire management.  Oaks, hickories, blueberries, grasses, and sedges, with a variety of fall wildflowers of various colors highlight the mosaic formed by different burning regimes.  Descending from these dry slopes, we enter a wet meadow and visit the Ward Reservation to investigate the classic kettlehole bog, one of the best examples in eastern Massachusetts.   The colors should be spectacular, with many end-of-season fruits and flowers.   This botany hike emphasizes the different ecologies of these very different sites. Walking is on a wide but steep path over the drumlin, moist in the meadow, and easy along the board walk through the bog.  Bring Newcomb’s Wildflower Guide, Peterson’s Fern Guide, and a hand lens, as well as water and lunch.  Limit 15 participants, fee is $32 for NEWFS or Trustees of Reservations members, $36 for non members.  To register, log on to http://www.newfs.org, or call 508-877-7630.
