Firewise Landscaping to Reduce Wildfire Risk: A 10-Minute University™ Presentation

This free class requires advanced registration by clicking here.

In 2020 Oregon experienced one of its worst wildfire seasons with more than one million acres burned and thousands of homes destroyed. The combination of continuing drought and increasing numbers of homes located in the urban/wildland interface suggests it is high time to make our landscape firewise.

This class introduces you to what firewise means and offers strategies that actively mitigate the impact of wildfire. It also acquaints you with fire-resistant plants by understanding factors that help a plant survive a fire and factors that make a plant flammable. Although there are no guarantees, making structures and the landscape firewise reduce the risk of fire damage.

This 30-minute class will be followed by a moderated Q&A session.
