Event Types > Community Events


For the month of May, Urban Forestry will be installing informational signs on select trees in Cathedral, Irving, and Ventura Parks. This will turn each park into a “Pop-up” Arboretum!

You can explore the signs in these Pop-up Arboreta on your own, with friends and family, or enjoy one of our guided tours. Urban Forestry staff and ISA Certified Arborist Patrick Key will lead walks to explore the trees we found in Ventura and Cathedral Parks. No registration required. 

Cathedral Park Cathedral Park, N Edison St. and Pittsburg Ave. — May 19th, 10:00 am to 1:30 pm

Tours on the hour, every hour!
