Restoring the Landscape After the Fire

Article by Josh Fodor.

After every fire I receive inquiries from homeowners and landscape managers, anxious to know what needs to be done immediately after a fire to help the landscape recover. My advice is: don't overreact. Native plants will take care of themselves. There's enough for you to do after a fire without adding unnecessary tasks. That said, there are some specific steps you should take.

Assess infrastructure and erosion risks. Drainage infrastructure is often damaged or destroyed in a fire. Culverts under driveways and roads may be crushed by fire fighting equipment or in the case of plastic culverts, completely melted. Inspect your drainage systems carefully and make a plan for increased runoff that will occur during the rains.

Plan ahead to remove invasive plants after the first rains. Many invasives, such as French broom, love fires. Plan ahead for the flush of growth that occurs when it rains so you can remove the invasives and let the natives reclaim the landscape. A botanist can help you identify invasive species or plan how to handle the rains.

Don't contaminate burnt areas with seeds. Purchased erosion control seed mixes, even California native mixes, will not be native to your property, and it is almost always better if you take advantage of the native seeds that are indigenous to the unique history and microclimates of your property. For critical areas that may have little to no native seed bank, seed with cereal barley (Hordeum vulgare) or similar non-native annual seed.

If you escaped this fire, prepare for the next. Minimize flammable debris and invasive fire-prone trees, and work with neighbors to reduce fire risk in your area. Decades of research have established that prescribed burning is the most effective measure for long-term risk management.
