Zone 0 landscaping: what stays, what goes, and what about the oaks

The ember-resistant zone rewrites the first 5 feet of your yard. It does not require scorched-earth landscaping, and in a county of oak valleys, citrus country, and coastal hillsides, the honest version has range.

Quick answer: The first five feet is the highest-leverage prevention: noncombustible ground cover in the 0 to 5 foot ring: no bark mulch, no woody shrubs against the wall. Draft statewide vegetation language scaled back blanket tree rules amid concern over mature trees and shade, and local authorities may allow well-maintained trees. Your Ventura County fire authority sets the specifics. Statewide Zone 0 is Proposed — not in force.

The redesign

The five-foot ring, replanted

Out: bark and wood-chip mulch, juniper and other resinous shrubs, climbing vegetation on walls, and plantings under eaves and vents.

In: gravel and decomposed granite, pavers and stone, low succulents in noncombustible beds where your authority allows plantings, and clean hardscape paths that double as access.

On trees, honestly: homeowners across California pushed back on early drafts precisely because mature trees provide needed shade, and the state responded. The withdrawn statewide draft is not in force. Local rules may allow well-maintained trees near the home. In Ojai, Meiners Oaks, and Oak View, where the oak canopy is the valley's identity, do not preemptively remove a healthy tree; verify with the Ventura County Fire Department first. Inside the City of Ventura, ask the city's own department.

Beyond five feet

Where landscaping meets wildland

On the hillsides above Ventura, along the Ojai Valley's edges, and on the Camarillo hills, Zone 0 is only the innermost ring: Zones 1 and 2 (5 to 30 and 30 to 100 feet) still govern the broader property. Wildland-edge homeowners need the full picture, not just the first five feet.

Questions

Quick answers

Do I have to remove my trees?

In most cases, no. Draft statewide vegetation language scaled back blanket tree restrictions after widespread public concern about mature trees and shade, and local rules may allow well-maintained trees. In the oak-canopied Ojai Valley this distinction matters enormously. What the first five feet clearly targets is combustible ground cover and shrubs against the structure. Verify specifics with your own fire authority before removing anything.

What replaces bark mulch in Zone 0?

Noncombustible ground cover: gravel, decomposed granite, pavers, stone, and concrete. The 5-foot ring converts to hardscape without losing the planting design further out.

Does drought-tolerant automatically mean fire-safe?

No. Some drought-tolerant plants are resinous and burn readily. In the ember-resistant zone the standard is noncombustible, not just low-water.
