Side-by-side comparison

Field	Flagstaff	Oro Valley
Protected tree definition	Flagstaff Zoning Code Division 10-50.60 (Resource Protection Standards) requires Forest Resource Inventory and preservation for development in ponderosa pine forest. Tree preservation standards apply to all qualifying sites; replacement required for removed qualifying trees. This is a distinct sub-regime from Sonoran-desert Arizona cities: the protected canopy is ponderosa pine (Pinus ponderosa) at 4-6 inch DBH and larger rather than native desert species.	Oro Valley Zoning Code Chapter 27 (Native Plant Preservation) and Environmentally Sensitive Lands (ESL) Overlay District require a Native Plant Preservation Plan for development on sites with protected native plants. Upper Sonoran desert plant palette dominates. Native plants must be preserved in place, transplanted, or salvaged per the preservation plan.
Heritage / landmark trees	Resource Protection Standards assign preservation priority to larger-diameter ponderosa pine and specimen trees identified during Forest Resource Inventory. No separate DBH-based heritage-tree designation; the inventory framework substitutes.
