Ontario FAQ
Can I remove a Joshua tree on my own land?
Not without a CDFW permit. Even on private land you must apply, document the take, pay mitigation fees, and may be required to relocate or replant. Hazard removals follow expedited processes.
What other desert plants are protected?
California Desert Native Plants Act protects yucca species, agave, mesquite, palo verde, ironwood, ocotillo, smoke tree, and barrel cacti. County ordinances may add additional native species in mountain and desert zones.
Rialto FAQ
Are native oaks protected in Rialto?
There is no Rialto-specific oak ordinance, but CEQA review on discretionary projects typically requires mitigation for native oak removal.
Can I remove a tree with a bird nest in it?
Not if the nest is active - state Fish and Game Code §3503 and the federal MBTA prohibit destruction of active nests. Wait until the chicks have fledged or consult a qualified biologist.
Does the Joshua tree law affect Rialto?
The Western Joshua Tree Conservation Act protects Joshua trees statewide. They are uncommon in Rialto proper but if present on your parcel, a state take permit is required to remove them.
