Tuesday, February 20, 2024 11 AM - 3 PM Cape Cod Museum of Natural History 869 Main Street, Brewster The Eco Expo is a mini-trade show featuring Brewster Chamber of Commerce businesses and organizations that focus on ecological as well as economic sustainability. The event, held at the Cape Cod Museum of Natural History, will occur during the Brewster schools' February vacation week. The BPC will once again have an informational table and activity for children, as well as a visit from "Shelly the Turtle!" The Eco Expo is free with admission to the museum, so you can enjoy not only this fun event but also all the museum's exhibits and attractions. For more information, visit the Cape Cod Museum of Natural History website.  Pictured above at Eco Expo 2023 are visitors and Shelly the Turtle.
"Critter Corner" is planned to be a quarterly column that highlights different species or species groups in and around Brewster ponds. Here is the first article by Ron Essig, BPC Board member and Citizen Science Team Coordinator. The first critters being featured in this new column are freshwater mussels - a group of at least six species. The most common is the Eastern Elliptio seen in the photograph below that inhabit shallow water and can be washed onto the shore after strong winds and storms. The least common are the Eastern Pondmussel and the Tidewater Mucket that are state listed species of concern. Other species that might be in Brewster ponds are the Alewife Floater, the Eastern Floater, and the Eastern Lampmussel. Freshwater mussels have an amazing life cycle including a parasitic stage in fish. In the spring, their fertilized eggs develop within the mussel into larvae called glochidia that are released into the water in the summer. The glochidia attach to the gills of host fish where they grow into juvenile mussels within a few weeks. Then they slough off and live on their own in the pond substrate while becoming adults. Some freshwater mussels need particular fish species as hosts, while others like the Eastern Elliptio are considered generalists. This species has been documented to successfully use as hosts Yellow Perch, Pumpkinseed, Bluegill and Banded Killifish that are all residents of most Brewster ponds. Freshwater mussels also play a unique role in pond ecology as filter feeders. Their feeding on microscopic algae and bacteria can remove excess nutrients and improve the habitat for other organisms. They can show large changes in abundance due to changes in food availability. For example, surveys in Walkers Pond in 2013 showed freshwater mussels to be scarce when phytoplankton levels were relatively low. However, their numbers increased considerably in 2022 surveys when phytoplankton levels were high. This change was beneficial to their predators like River Otters and Muskrats. About 75 percent of North America’s almost 300 freshwater mussel species are endangered, threatened or of special concern at federal or state levels. So, we are fortunate to have these unique species in Brewster ponds. You can help protect them by tossing them back into the water if you find them alive on the shore and by taking the steps advocated by BPC to keep ponds clean.  Eastern Elliptio.

"Volunteerism is the voice of the people put into action. These actions shape and mold the present into a future of which we can all be proud." - Helen Dyer Membership and volunteerism do matter, and our voices matter, too. Our mission to protect and improve our ponds demands attention to learning through science. It also means using our voice to take this knowledge to advocate for changes necessary to safeguard our freshwater resources. That is not always easy but is paramount to leaving behind a Brewster of which we can be proud. Let’s use our voice and have thoughtful, honest and respectful conversation on how to protect our environment. With your continued support, our voice and advocacy will continue. Your annual membership renewal is a testament to your decision to protect our ponds. We are off to a good start with our 2024 annual appeal, but still have a long way to go. Let’s hit our member and renewal goals of 70% this year! In 2024, the BPC will:
The Membership Team looks forward to reaching out to you during our "call-out" period beginning in January. Having a two-way conversation allows us to get your input and answer any questions that you may have out our plans and programs. The BPC board hopes you will take a moment to donate by using the "Donate" button below. Please e-mail any comments, ideas, or questions to [email protected] with the subject title "2024 Appeal." The Membership Team will answer all questions and ideas submitted. Thank you for your support!  Photo of Sheep Pond guardian, submitted by Fred Budreski
