What counts as fuel
Fine fuels such as dry grass, needles and small twigs catch fast and carry fire quickly. Heavier fuels such as logs and big limbs burn longer and hotter. Live shrubs with oils, such as junipers, add to the load, and so does anything dead that is still standing or leaning in the brush.
Arrangement matters as much as amount. Fuel that runs in a continuous path from the ground to the tree crowns lets a fire climb (see ladder fuels).
Why it matters in Northern Nevada
Cheatgrass, sagebrush, bitterbrush and dead pines on dry slopes build up fuel that can cure to tinder by midsummer. A lot that was never cleared can carry far more fuel than the lot next door. The Living With Fire guide advises removing dead vegetation and thinning in Zone 2, 30 to 100 feet out.
Cut limbs and brush add to the load if they are left in piles; see slash and pile burning.
What an arborist does about it
Fuel reduction is a Battle Born service: removing dead trees, pruning up the lower limbs, clearing brush with mowers and mastication, and hauling or chipping what comes off. The crew works to the zones in the guide. The arborist's walk-through covers what to take out and what to leave. See lot clearing and defensible space and fire mitigation.
Fuel load builds back, too. Grass and brush regrow each year, so a cleared lot needs a return visit for mowing, and dead limbs keep falling. Ask the arborist what to expect so the work does not come as a surprise.
Seasonal timing matters. Grass and weeds cure and dry through summer, so mowing before they cure is more useful than after a fire starts. Ask the arborist what a return visit would involve on your lot.
