California provides statewide protections for native oak woodlands and heritage trees through CEQA review, Public Resources Code, and Forest Practice Rules that apply uniformly.
Public Resources Code Section 21083.4 requires counties to determine whether projects with significant oak woodland impacts must mitigate under CEQA, including conservation easements or in-kind tree planting. PRC Sections 4799.06-4799.12 (Oak Woodlands Conservation Act) authorize the Wildlife Conservation Board to fund oak protection. The Z'berg-Nejedly Forest Practice Act (PRC 4511 et seq.) regulates commercial timber operations including heritage species. Local agencies cannot exempt projects from CEQA oak review and must apply state Forest Practice Rules to qualifying timberland conversions.
CEQA noncompliance may void project approvals; Forest Practice Act violations carry civil penalties up to $10,000 per violation per day.
