Fire Protection Steps You Can Take
The top left photo shows a fairly classic ladder fuel issue whereby grasses could ignite the smaller bushes and then ignite the larger bushes and then finally ignite the large pine tree, which can send embers onto the roof and damage the exterior of the home.
The bottom left photo shows two very large and very flammable rosemary bushes under the desert willow.
The photo to the right shows removal of the rosemary bushes and the limbing up of the tree to create separation and reduce the risk of the tree igniting.
