What is the minimum height for mowing grass in defensible space zone 2?

The minimum height for mowing grass in defensible space zone 2 is 6 inches. This height is significant because it helps to reduce the availability of dry, fine fuels that can easily ignite and contribute to the spread of wildfire. Mowing grass to this height maintains sufficient moisture and creates a barrier that slows fire intensity, thereby enhancing the protection of nearby structures and creating a more defensible area.

Moreover, maintaining grass at this height supports ecosystem health, allowing for a mix of grass and soil moisture that can prevent fire spread. Taller grasses can also facilitate healthy growth while still providing a buffer against fire, balancing both fire mitigation strategies and the preservation of local flora. Understanding these maintenance strategies is crucial for effective wildfire risk reduction in defensible spaces.
