Los Angeles County
South Gate's Municipal Code (Chapter 5.33) does NOT enumerate a list of protected species by botanical name. Instead it protects all public trees defined by size potential (mature height ≥15 ft) and location (≥1/2 of trunk on public land). California state law independently protects certain species: native oaks (Quercus spp.) on county/unincorporated land via PRC §21083.4 CEQA review, and any tree designated as habitat for state/federally listed species (e.g., raptors, monarch overwintering eucalyptus) under Fish & Game Code §3503/§3513 (bird nests).

Pasadena FAQ
Does the oak ordinance apply to dead trees?
A confirmed dead oak generally does not require a permit, but a certified arborist report and Regional Planning concurrence are required first. Hazardous live oaks may qualify for an emergency permit with reduced fees and expedited review.
What if construction must encroach on a protected oak?
Submit an Oak Tree Permit application with arborist-prepared protection plan, root-zone fencing, and impact analysis. Regional Planning may require redesign, deep watering, or replacement plantings before approving encroachment.
South Gate FAQ
Are oak trees specially protected in South Gate?
California's main oak-protection statute (PRC §21083.4) applies to discretionary projects in unincorporated counties, not incorporated cities like South Gate. Locally, oaks on public land are protected the same as any other public tree under SGMC 5.33; oaks on private land in South Gate have no special local protection unless a planning condition of approval applies.
Can I cut down a tree in the spring?
Be very careful. California Fish & Game Code §3503 and the federal Migratory Bird Treaty Act make it unlawful to destroy any active bird nest — even on private property. Industry-standard practice is to avoid tree work between February 1 and August 31, or to retain a qualified biologist to perform a nest survey within 3 days of the work.
What about palm trees — are those protected?
Yes when on public land. Mexican Fan Palm and Date Palm specimens lining South Gate's streets are 'public trees' under SGMC 5.33 (they exceed the 15-ft mature height threshold) and require a Public Works permit to remove or prune.
