On November 28 from 6:30-8pm at the Waltham Public Library (735 Main St, Waltham), please join us for “Saving Pollinators in Your Yard.” Speakers are Brandeis Senior Lecturer in Ecology, Eric Olson, and Native Plant Garden Designer,  Florrie Wescoat. Eric will talk about the impact of climate change on our ecosystems and Florrie will talk/show how easy and essential it is to make an ecosystem in our own yards. We will have useful handouts, too. This program is sponsored by the Waltham Cultural Council.
