Arbor Week Poster Contest

For California youth ages 5-12

Arbor Week Poster Contest

Each year California kicks off Arbor Week with a poster contest. California Arbor Week is an annual celebration of trees which takes place March 7 to 14. Across the state, communities honor trees. You can participate too by thinking about the importance of trees and creatively sharing your love and knowledge of them in a piece of art. Any California youth age 5-12 can submit a poster.
