Join us for a day of collecting walnuts in Bear Canyon! Walnuts are especially important because they provide food for the Santa Catalina gray squirrel, a sub-species of the Arizona gray squirrel that seems to be less common than it used to be due to habitat changes and competition with the introduced Abert's squirrel. The seeds we collect will be grown out to be re-planted in Bear Canyon, and other nearby canyons.
