Frequently Asked Questions

Which tree species are protected as native trees in Pasadena?
Thirteen species qualify under Section 8.52.020(P) once their trunk exceeds 8 inches in diameter: coast live oak, Engelmann oak, canyon oak, California sycamore, California walnut, scrub oak, valley oak, California bay, cottonwood, California alder, black cottonwood, arroyo willow and California buckeye.
Do I need a permit to remove a native oak tree in my yard?
Yes. Section 8.52.085(B) prohibits removing a protected native tree without a permit, and the city manager can only approve removal after finding one of six specific justifications under Section 8.52.075(A), such as poor tree health or a genuine hardship to the property owner.

They're automatically protected. Section 8.52.066 states that any tree meeting the native, specimen, landmark, landmark-eligible or mature tree definition in Section 8.52.020 is automatically subject to this chapter's protections as of the ordinance's effective date, with no separate designation hearing required.
