24-Hour Volunteer Tree Planting Relay a.k.a. Treelay

Every year, the Alliance engages communities, companies, and conservationists to plant thousands of trees in the Chesapeake Bay watershed. We’ve been looking for a big, bold way to celebrate the fantastic tree planting efforts of our volunteers. Hence, The 24-Hour Volunteer Tree Planting Relay also known as Treelay for short. Treelay is a series of volunteer tree plantings scheduled back-to-back over a 24-hour period (hence the relay).

The Alliance’s 2022 Treelay is in its inaugural year, and we plan to kick things off with a bang! We will have nearly 10 plantings throughout the watershed: 6 plantings around the clock in Pennsylvania, and one planting each hosted by our teams in Maryland and Washington, DC.

For decades, the Alliance for the Chesapeake Bay has engaged communities in watershed conservation via volunteer tree plantings.

Not only do volunteer tree plantings help accomplish important work and increase awareness about watershed issues, but they also empower communities to take action and can cascade into more locally-led stewardship. This is why we’re on a mission to get as many community members outside as possible.
