Robert Gegear

Ever wonder which bees benefit from your yard or how you can help rare species? Come learn about eastern North American plant-pollinator systems with Dr. Gegear. He will also highlight his Beecology Project, a citizen science project that uses eco-technology in order to collect data on ‘at risk’ plant-pollinator systems native to New England.

Dr. Robert J. Gegear is a Professor in the Department of Biology at University of Massachusetts Dartmouth. He has been studying the neuroecology and conservation of eastern North American plant-pollinator systems for over 25 years. He is also the founder the Beecology Project, a citizen science project that uses eco-technology in order to collect data on ‘at risk’ plant-pollinator systems native to New England.

Russ Cohen

Join Russ Cohen, expert forager and author of Wild Plants I Have Known…and Eaten, for a 60-minute slide show featuring at least two dozen species of native edible wild plants suitable for adding to your own landscape, or nibbling on as you encounter them in other locales.  Keys to the identification of each species will be provided, along with edible portion(s), season(s) of availability and preparation method(s), along with guidelines for safe and environmentally responsible foraging. 

Until his retirement in June of 2015, Russ Cohen’s “day job” was serving as the Rivers Advocate for the Massachusetts Department of Fish and Game’s Division of Ecological Restoration, where one of his areas of expertise was in riparian vegetation. He has set up a small nursery (in Weston MA) where he grows/keeps over 1,000 plants that he propagates from seed (some of which he collected himself), as well as obtains from other sources, such as the Native Plant Trust.

All About Backyard Birds with Michele Grzenda 

Click Here to Watch Recording 

Michelle GrzendaAre you fascinated by all the visitors coming to your family’s bird feeder? Join Michele Grzenda to learn skills to identify all those colorful feathered friends you admire. She will teach you common songs and calls of our backyard birds as well as some helpful mnemonic memorization.

Michele Grzenda is the Conservation Director for the Town of Lincoln where she blends the fields of environmental regulation, open space protection, and land management. However, Michele's real passion is sharing her love of birds with others and has led hundreds of birding programs for Mass Audubon, Appalachian Mountain Club, and several community education organizations.  Those early observations sparked an interest that prompted her to study wildlife management and environmental conservation at University of New Hampshire.
