A big concern that homeowners often express is that being Firewise might mean getting rid of all of the trees on their properties. Fortunately, there are quite a few things to do that make trees and homes safer that do not involve mass deforestation.
In some cases, simply removing overhanging branches or limbing trees up from the ground will make you sufficiently resistant from embers or firebrands. Healthy, well-maintained trees or forestland on your property looks attractive and not necessarily pose a major risk for the spread of wildfire.
Each site is slightly different, and the best bet is to consult an arborist or forester on the species and arrangement of the trees, as well as other factors. You may need to remove or thin out some trees to maintain the health of the rest, and it will leave you with better landscaping and a more secure home out of the bargain.
