One of Thoreau’s beloved landscapes, referenced often in his writings, Gowing’s Swamp is a rare and beautiful bog in a kettle hole tucked away below a glacial ridge. On June 5 at 1, Native Plant Trust will walk the loop around the bog in Sudbury and explore the thriving community of northern bog plants such as pitcher plant (Sarracenia purpurea), bog rosemary (Andromeda polifolia), bog laurel (Kalmia polifolia), small cranberry (Vaccinium oxycoccos), large cranberry (Vaccinium macrocarpon), and black spruce (Picea mariana). We will observe the many vernal pools and the bird and mammals in this unusual habitat. Neela de Zoysa leads, and the field trip is $30 for NPT members, $36 for nonmembers.
