| NHANRS Presents:
Winter Botany Workshop
Saturday December 5, 2026
6.5 contact hours
WORKSHOP DESCRIPTION
This WINTER BOTANY workshop consists of a thorough review of botanical morphology during the winter, training in the use of a dichotomous key, hands-on experience in the classroom and in the field with a large inventory of twigs from all the major botanical families found in the Northeast, and professional shortcuts to help students identify an unknown plant in winter. The morning classroom session will be held in the SPNHF Conservation Center conference room. The afternoon field trip covers a wide range of elevations and habitats along the Merrimack River floodplain at the Conservation Center that feature a wide variety of flora in a natural environment. Workshop will include morning refreshments and lunch. Students should dress for a winter field trip in dry to moist environments.
