Summary

California provides statewide protections for native oak woodlands and heritage trees through CEQA review, Public Resources Code, and Forest Practice Rules that apply uniformly.

(b) As part of the determination made pursuant to Section 21080.1, a county shall determine whether a project within its jurisdiction may result in a conversion of oak woodlands that will have a significant effect on the environment. If a county determines that there may be a significant effect to oak woodlands, the county shall require one or more of the following oak woodlands mitigation alternatives to mitigate the significant effect of the conversion of oak woodlands: (1) Conserve oak woodlands, through the use of conservation easements.

Full Breakdown

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. The Oak Woodlands Conservation Act (Fish and Game Code sections 1360-1372) authorizes 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.

Violations & Penalties

CEQA noncompliance may void project approvals; Forest Practice Act violations carry civil penalties up to $10,000 per violation per day.

What counts as oak woodland under PRC 21083.4?
An oak stand with greater than 10% canopy cover that includes one or more native oak species, as defined by the statute.
