Each year California kicks off Arbor Week with a poster contest. California Arbor Week is an annual celebration of trees that always falls on March 7 to 14. Across the State, communities honor trees. This includes an annual poster contest with a new theme each year. California youth ages 5-12 are invited to participate by thinking about the importance of trees and creatively sharing your love and knowledge of them in a piece of art.

The 2021 Poster Contest theme is Trees Invite Me Outside. View more information about the contest here:
