FUELS AND SHADED FUELBREAKS

shaded fuelbreaks where brush (like manzanita and ceanothus) is controlled and trees are thinned A rule of thumb for thinning trees in fuelbreaks is dbh+4+1/3 (dbh is (diameter at breast height or 4 5') Take the diameter of the tree in inches add 4 then multiply by 1 33 to get the spacing of leave trees in feet So between 11-inch diameter trees you would want a spacing of 20 feet

FUEL BREAK

firebreaks (permanent or temporary strips of bare or vegetated land planned to retard fire) Fuel breaks aid firefighters by slowing fire spread under normal burning conditions However under extreme conditions even properly designed fuel breaks stand little chance of arresting a large fire regardless of firefighting efforts Such fires in a phenomenon called "spotting " can drop

Shaded fuel breaks act as strategic defensible landscape to reduce fire speed and severity improve suppression by ground crews and air attack The purposes of strategic fuel modification are to separate communities or groups of structures from the native vegetation and break up large expanses of flammable fuel into smaller blocks all with the purpose of reducing fire loss and damage A

The use of shaded fuelbreaks in landscape fire management

Shaded fuelbreaks (where some forest canopy remains) and larger landscape fuel treatments such as prescribed fire are receiving renewed interest as forest protection strategies in the western USA The effectiveness of fuelbreaks remains a subject of debate because of differing fuelbreak objectives prescriptions for creation and maintenance and their placement in landscapes with differing
