This October, the Alliance will be hosting back-to-back tree plantings in a first-ever relay-style event to get over 5,000 trees in the ground over a 24-hour period. Known as “Treelay,” the event will take place at 8 different sites across the Chesapeake Bay watershed, and trees will be planted continuously for 24 hours straight. Our teams will hold 6 plantings back-to-back in Pennsylvania, one in Maryland, and one in Washington, DC.
