Arbor Week Poster Contest

Join us in congratulating our 2024 Arbor Week Youth Poster Contest Winners! 🌳 👏

This year, California youth ages 5 -12 from all over the state submitted original artwork with the theme “I ❤️ Trees Because…” The art contest encouraged students to think about why they love trees and how trees make our communities healthier. We had over 200 entries from young tree heroes across the state, and 8 lucky winners. Congratulations to our winners and a big shout out to all California youth who participated. Thank you for helping celebrate California Arbor Week through your art and love for trees.

A big thank you to Blue Shield of California for sponsoring this year’s contest, and heartfelt thanks to our Arbor Week Poster Contest partners CAL FIRE and the USDA Forest Service!

Thank you to our 2024 Poster Contest Sponsor, Blue Shield of California!
