Side-by-side comparison
| Field | Flagstaff | Phoenix |
|---|---|---|
| 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. | No citywide DBH-based private tree removal permit. Phoenix Zoning Ordinance Section 507 (Landscape and Buffer Standards) governs required landscape plantings and preservation during development review. Native Plant Preservation requirements apply in designated zones (e.g., Desert Preservation overlays) where saguaro, ironwood, palo verde, mesquite, and ocotillo must be inventoried and preserved or transplanted. Arizona Native Plant Law (ARS 3-901 et seq.) applies to private undeveloped land statewide regardless of municipal code. |
| 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. | No formal municipal heritage-tree designation. Street trees in the right-of-way are regulated by Parks and Recreation / Street Transportation. Native plants on development sites receive inventory and preservation review under landscape standards. |
| Who can apply | Property owner or authorized agent; Forest Resource Inventory prepared by ISA Certified Arborist, Registered Consulting Arborist, or qualified forester | Property owner or authorized agent; development projects coordinated through registered landscape architect or design professional |
| Replacement ratio | Caliper-inch mitigation per Division 10-50.60 for removed qualifying trees; preservation percentages by zone | Landscape code-based replacement (site-specific by zone and project type); salvaged native plants reused on-site where feasible |
| Replacement details | On-site replacement preferred with ponderosa pine or approved native; off-site replacement or in-lieu contribution permitted under some conditions. | On-site preservation and transplant preferred; replacement plantings per landscape standards. No dedicated city tree-mitigation fund. |
