Learning About Nature from Experts

In winter we choose a theme supported by speakers and videos. See below for summaries, resources, and links to the videos

2026 Theme: Water and Our Climate

Our Pioneer Valley landscape has experienced water hazards in recent years — farms have flooded, while wells have run dry and droughts have been declared.  This 2026 season, Greening Greenfield explores water events in the valley. 

Our choice of this topic was driven by the fact that although in the Northeast we do not experience persistent drought, scientists say that worldwide all the continents are drying. Since the water cycle is driven by vegetation, it is concerning that over the past 10,000 years our planet has lost at least 50% of its vegetation. We are inspired by Walter Jehne, Australian Climate Scientist, who says that by increasing vegetation by 4%, we could significantly stabilize our climate.

In this series, we start by looking deeply at the soil sponge, which plays a key role in supporting vegetation and the water cycle. We then look to beavers to learn about water management. In the final talk, we bring it home to what we can do in our yards and community to help restore our climate and more.

Regenerating the Pioneer Valley’s Soil Sponge and Living Climate

Didi Pershouse, an internationally known author and educator kicked off the 2026 season series.  She talked about the importance of soil sponge, and how we can build it. Click here for a video of her talk, January 2026.

WHAT CAN WE LEARN FROM BEAVERS?

Dr. Christine Hatch, UMass professor, UMass Professor of Water Resources and Climate Change, talked about how many of beavers’ landscape alterations result in ecosystem enhancement, rather than degradation, and asked if we would benefit from co-existing with them in our densely populated landscapes.  Click HERE for a video of her talk and more, February 2026.

HOW TO EMBRACE WATER IN OUR LANDSCAPE, AND SUPPORT BIODIVERSITY

Kate Cholakis, Landscape Architect, explained how we can analyze and manage water in our yards and community by encouraging water to soak in rather than run off, by planting native habitat, shrinking our lawns, building rain gardens and more. These actions will help clean storm water, replenish our aquifers, support the water cycle, add beauty, and help restore our climate. Click HERE for a video of her talk, handouts, about Cholakis and more, March  2026.

Winter 2025 Theme:  Supporting Birds with Native Habitat

How to Choose Bird-Friendly Plants

Martha Gach holds a PhD in ecology and evolutionary biology. She worked at Mass Audubon for over 25 years. She asked the question “Do you want to attract and support birds?”   If yes, she then challenged and invited everyone to choose native plants to create an environment that does just that.  Attendees took home specifics as well as general principles that can be applied to a variety of spaces from patios to parks.   Click here for a video of the presentation, and hand-out here.  January, 2025

Sharing Your Yard with Birds

Greenfield’s own Pat Serrentino holds a Masters degree in Zoology from the University of Rhode Island, and has extensive experience in wildlife ecology and management, habitat restoration and public education. Pat focused on the actions that residents / homeowners can take to not only attract birds to their yards, but also keep them safe and healthy. She talked about supplying water and bird houses, how to prevent birds from striking windows, and urged us to avoid using pesticides.  Click here for a video of the presentation,  February, 2025.  Pat’s extensive bird resource list here.  

Berries for Birds

Susan Smith Pagano, Ph.D. Professor of Biology at Rochester Institute of Technology with research focused on the role of diet for migrating songbirds at stopover sites in the Northeast.   Her research indicates native fruiting shrubs provide more of what birds need and when they need it.  Her conclusion: If we want to support birds, we need to incorporate a variety of native plants that produce calorific, high-fat, and antioxidant-rich berries during migration. Click here for a video of the presentation, March, 2025, Hand-out here

2024 Theme: Working with Nature to Restore our Climate

Regenerating Life

The first two parts of this three-part beautiful documentary film by John Feldman was viewed. It explored how life on our planet came to be. The documentary revealed fascinating insights into the role of water and plants in nurturing and balancing pathways to restore biodiversity and our climate.    Click HERE to rent or buy the films.

  • Life Sustains the Climate Part 2, March, 2024.

Healthy Soils at Home

Rachel Lindsay, Ecologist and Designer, Regenerative Design Group presented ways to protect soil health and increase climate resilience at home and beyond.  She introduced us to the 2023 Massachusetts Healthy Soils Action Plan, the first statewide comprehensive plan of its kind that addresses non-agricultural soil management. Click here for a video of the presentation. April, 2024.
