Tucson protects heritage and specimen trees, particularly mature native desert trees, through its Native Plant Preservation Ordinance and the Environmental Resource Zone overlay. Large, mature saguaro cacti (especially those over 6 feet tall), old-growth ironwood, and mesquite trees of significant size are given special consideration in development review. The city's Urban Forestry Division manages heritage trees on public property.
While Tucson does not have a formal heritage tree registry like some cities, large native trees and cacti receive protection through development review processes. Saguaro cacti take approximately 75 years to grow their first arm, making mature specimens irreplaceable. The Environmental Resource Zone requires preservation of significant native vegetation. The Tucson Urban Forest Plan identifies priority areas for tree canopy preservation and expansion.
Destroying heritage-quality native vegetation can result in significant fines, project delays, and requirements for enhanced mitigation. Cutting down protected trees without authorization may result in fines per plant plus replacement costs based on size and age.
