It’s time to nominate your favorite neighborhood tree for a Como Tree Appreciation Award. The District 10 Environment Committee is sponsoring the awards as a way to treasure our valuable trees and promote tree planting. Nominate a residential tree—big or small, old or new, yours or a neighbor’s—at district10comopark.org/nominateatree.html. Nominations will be accepted through May 25. Winners will be notified by late June.
