A great idea from Ed McFadden of Philmore or Fillmore in the local language.
You can always do something to prevent or correct the Big 4 that seem to strike avocados on a regular basis somewhere in California. Avocados in the back country are right up against areas that can burn easily. A fast fire can send embers into an orchard which can burn through the thick leaves in a slow burn. If it gets up against leaves piled up against the trunk, it can girdle the tree, killing it. The slow burn can continue through the orchard torching the irrigation lines. With a small fire break where the leaves are removed in a small alley, the burn can be slowed or stopped.
Leaves are great for erosion control, for nutrient cycling and disease control, but if they mean increasing potential for fire spread, it's a good idea to remove a little of it. Ed has found that a backpack blower can rapidly remove leaves from around the base of trees and create a narrow fire break that can reduce fire damage to trees.
Avocado orchards are notable for their ability to actually reduce fire hazard and slow major fires as has been shown in fires in San Diego, Ventura and Santa Barbara. This is partly due to running sprinklers during wild fire. But tree loss can still occur, especially when electricity goes down and pumps can't run.
Little rain this year or too much rain this year can always pose a hazard to avocado orchards. This sure seems like a good idea to me. And maybe it's time to start thinking about fire season now.

And another observation from 2008
And orchards being recognized as valuable in a fire prone area by the Santa Barbara Fire Safe Council
Orchards are another fire mitigation strategy, one that has already benefitted Goleta but has played a lesser role for Santa Barbara and Montecito where fewer orchards now exist. More orchards could be planted
The fire burned in the hills until July 28, blackending nearly 10,000 acres but causing relatively little structural damage. Firefighters credited the agricultural barrier of green avocado orchards and irrigated soil surrounding Goleta with saving the town.
But most importantly, how to prepare for fire. Read ON
