A Note to Citizens:
If your utility company participates in the Tree Line program, it might be good to let them know that you think your community trees are an important asset and that you appreciate their participation in the Tree Line program. If your local utility is not listed, encourage your municipal utility or local utility company to join the Tree Line USA program.
