Community Buffer Zones and Fuel Modification Areas

MAST is helping fund and coordinate the creation of “buffer zones." Think of buffer zones as defensible spaces, only bigger. These “zones” and “spaces” are designed with the same concept in mind: that with hard work and a bit of good fortune, fires starved of fuel will often slow enough to be wrestled under control or the flames will simply flicker out on their own.

Strategically implemented on the edge of communities or just nearby, buffer zones are fuel-treatment areas that have been cleared of dead trees and vegetation, and thinned of densely packed plants and trees. The size of some buffer zones may be 50-feet wide and one-block long, others may be one-mile long and 500 yards wide. The formula for the size is straightforward: Whatever is needed and doable.
