Preparing your property for fire does not mean removing all your trees. There are many things you can do to make your home resistant from embers or firebrands that may involve simply removing overhanging branches or limbing trees up from the ground.
Remember that healthy, well-maintained trees or forestland on your property will provide many benefits and not necessarily pose a major risk for wildfire spread. Your site-specific risk depends on the species and arrangement of the trees, as well as other factors. Consult an arborist or forester to learn more about the health of your landscape. Removing or thinning out some trees may actually be necessary to maintain the health of the rest.
