On Sunday, May 17, in celebration of Arbor Day, the Rockland Tree Board will host a tree planting at MacDougal Park.

The family-friendly event will take place at 1 p.m., when participants will be invited to help plant a Yellow Birch sapling.

"Across the country, Arbor Day is celebrated to recognize the value of trees in our communities," said a City of Rockland news release. "In backyards and across the City, trees provide needed shade, habitat for an incredible array of insects and birds, help clean and cool the air, and are a beautiful addition to our community."
