Which of the following is a recommended action to create defensible space?

Creating defensible space is crucial for protecting property from wildfires. The correct action to promote this safety measure involves maintaining a clear area around the structure to reduce the risk of flames spreading. Trimming branches above 6 feet is essential because it prevents tree branches from touching the roof or walls of the house. This action creates vertical space that helps to stop fire from climbing up into trees and reduces the risk of an ember igniting the structure or surrounding vegetation.

In this context, other actions are counterproductive to creating defensible space. Planting dense shrubs near the house eliminates crucial separation that protects the structure from fire. Installing a wooden roof can increase the risk of fire due to wood's combustibility, compared to non-combustible materials like metal or tile. Allowing dry brush to accumulate not only raises the fire hazard but also creates a greater likelihood of flames spreading rapidly to structures.

Thus, trimming branches above 6 feet aligns with fire prevention strategies by minimizing potential fuel sources and maintaining a safer environment around the property.
