Arbor Day in Flagstaff is August 25th! (We know, National Arbor Day is in April, but that's a terrible time to plant a tree in Flagstaff.)
Join Flagstaff Open Space and Northern AZ Audubon to plant trees along the Rio de Flag at Picture Canyon! Wear sturdy shoes and a sunhat (well, other clothing too...), and bring work gloves, drinking water, and snacks, but we'll have extras!
