Which of the following actions helps maintain defensible space in zone 2?

Maintaining defensible space in zone 2 is essential for reducing the risk of wildfire encroachment on structures. Creating a crown separation of at least 10 feet helps in several important ways. It minimizes the potential for fire to climb from the ground to the crowns of trees, which can spread flames rapidly through the canopy. By ensuring adequate separation between tree canopies, you reduce the chance of fire jumping from one tree to another, enhancing the overall safety of the property.

In addition, maintaining this distance allows for better air circulation and reduces competition among trees for water and nutrients, which helps the trees stay healthier and more resilient to pests and disease—all important factors in wildfire mitigation. All of this contributes to a more effective defensible space, making it less likely for fires to spread unchecked near homes and developments.
