Sustainability at Home: Small Ponds + Backyard Water Gardens
2026-06-04 18:00 - 19:30 | Washington County Conservation District, 50 Old Hickory Ridge Rd Suite 1, Washington, PA, 15301, United States
Join ALT for round 5 of our popular workshop series: Sustainability at Home! This series focuses on living a more environmentally-friendly lifestyle through at-home sustainability practices. For this workshop, ALT is partnering with our friends at Interactive Environmental Programs + Penn State Extension to bring you an exciting new workshop on backyard ponds and water gardens!
The health of your small pond ecosystem depends on creating a sustainable habitat by maintaining the plants and water resources in your pond. Susan Boser, Water Resources Educator with Penn State Extension, will discuss the benefits of choosing native aquatic plant species for your pond. Participants will learn how to monitor their pond water quality to ensure that plants and animals can thrive. We will not be discussing the construction of ponds at this workshop.
During the second half of the workshop, participants will explore the frogs, toads, turtles, and salamanders most commonly attracted to home water features with local naturalist April Claus of Interactive Environmental Programs. Learn why these animals are vital indicators of a healthy environment and how their presence reflects local ecosystem health. Special attention will be given to local amphibians, including how to identify common species by their calls, behaviors, and seasonal activity. Live native animals will be featured to help sharpen identification skills and provide a closer look at their life histories and survival requirements. Attendees will gain practical insight into what sounds to listen for, when to expect them, and how simple, wildlife-friendly pond design choices can encourage biodiversity while coexisting safely with these fascinating animals.
*Note: Due to having two incredible speakers on this topic, this class is slightly longer than the rest of our series.
Each attending participant will receive one set of materials to help them get started at home (valued at $100!). Children under 18 are not eligible to receive the materials; please do not purchase a ticket for any children that may be in attendance with you. You must be present for the entire workshop to receive the provided materials. No walk-ins are permitted.
Generous funding and support for this series was provided by the EQT Foundation.

Protect the greenway from invasive vine species

Registration is required so we can communicate in case of any necessary changes.
Churchill Valley Greenway, the former site of a golf course and country club, is steadily re-wilding with the care of stewards and volunteers.

Join us to tackle one invasive plant species in particular: Mile-a-Minute vine (Persicaria perfoliata).
Volunteers will use gloves and garbage bags to uproot vines and remove them from the greenway. Preventing the spread of this fast-growing invasive plant species will aid in our restoration efforts in the forests and meadows of Churchill Valley Greenway, and we can’t do it without you!
Volunteers can expect to walk up to two miles mostly on paved walking paths and are asked to work at their own pace and comfort level. Tools and gloves will be provided. Light snacks and water will be provided; please bring your own reuseable water bottle. Closed toe shoes and long pants are required.
