The Green Tier Legacy Community Committee will mark Earth Week and Arbor Day by giving away free trees to the public on May 9 in Sister Bay.

The event will take place from 9 a.m. to 3 p.m., or while supplies last, at the Piggly Wiggly in Sister Bay. The giveaway is part of a broader effort to promote sustainability and support The Big Plant Door County, a countywide initiative focused on increasing tree coverage.

Volunteers will be on hand throughout the day to distribute trees and provide basic planting guidance to residents.

Organizers say the effort aims to encourage community members to take part in environmental stewardship while contributing to the long-term health of local ecosystems.

Residents are encouraged to arrive early, as quantities are limited and trees will be distributed on a first-come, first-served basis.

The event is free and open to the public.
