Prescribed burning, restoration thinning, or a combination of both are effective at reducing the risk of catastrophic wildfire in California.

<p>A 20-year experiment in the Sierra Nevada confirms that different forest management techniques &mdash; prescribed burning, restoration thinning or a combination of both &mdash; are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.</p>
