Rescheduled to Thursday, March 12

Join us for a public screening of The Pollinators at Harbor Theater in Boothbay Harbor on Thursday, March 12 at 6 p.m. (Doors open at 5 p.m.) Appetizers and concessions will be available prior to the screening.

Per director Peter Nelson, The Pollinators is “a cinematic journey around the United States following migratory beekeepers and their truckloads of honey bees as they pollinate the flowers that become the fruits, nuts and vegetables we all eat.” This film focuses not only on these vital pollinators, but also on the beekeepers, farmers, chefs, and academics who interact with them, offering the audience a broader perspective about honey bees’ importance and the threats to both their survival and our food security.

As a special addition to the evening, CMBG’s CFO/COO and Master Beekeeper, Erin MacGregor-Forbes, will give a brief introduction prior to the film—along with a little buzz about our next season’s new learning apiary. Erin MacGregor-Forbes is former Chairman of the Eastern Apicultural Society, the largest noncommercial beekeeping organization in the United States.

Section II: Plants and Practice

Resilient landscape practices are connected to the evolving environment and sustain and regenerate under stressful environmental conditions, rather than falling victim to stressors. This new in-depth program is designed to provide advanced and comprehensive content to support landscape practitioners in reaching the next level in their business.

Courses in Section II examine the use of native plants for biodiversity and beauty for high performance with minimal input as well as long-term management of Green Infrastructure (GI) and contractor-to-client communication essential for successfully maintaining resilient landscapes. Students who wish to enroll must be current professionals in the landscape industry or enrolled in a college-level landscape, agriculture, or horticulture program. For daily agendas and learning objectives, please visit here.

If interested in registering for both Section 1 and 2 of Resilient Landscapes in Built Environments, please call 633-8000 directly for the combined discounted price.

A 10% fee will be charged in event of cancellation.

The Earth in Her Hands: 75 Extraordinary Women Working in the World of Plants

This year’s Heafitz lecture focuses in a wholly unique way on the intersection between horticulture and our everyday world. This year, we’re highlighting the women whose work has enriched and expanded these intersections over the last 25 years. With her book, The Earth in Her Hands: 75 Extraordinary Women Working in the World of Plants, author Jennifer Jewell explores and celebrates how the plant world is improved not only by a greater representation of women in general, but by the diversity among them. Her work chronicles how the world of plants is a more viable and creative career path for women than ever before and how it is demonstrating greater social and environmental responsibility, in large part due to women’s contributions.

Walking through the profiles of women doing innovative work in all fields of horticulture, from botany to environmental science, landscape design and architecture to social justice, breeding and seed science to garden writing and photography, and administration to research and public policy, her work illustrates how the many challenges of our environment, economy, culture, and individual worlds can and are being met by cultivating an interdependence with plants.

These paradigm-shifting women include representatives from the United States, England, Ireland, Wales, Canada, Australia, India, and Japan and range across race, ethnicity, socio-economic and religious backgrounds, sexual orientation, and age in a way that transcends preconceived notions of what horticulture/gardening is and what plantspeople/gardeners look like. These women and their work have profoundly positive impacts on the larger aesthetic, environmental, cultural, and economic world, making them profoundly inspiring role models for us all.
