How they ignite a house
An ember is a small thing, but a landing place full of dry needles, leaves, bark mulch or stored wood can turn one into a fire. Embers can travel well beyond the flame front, so a house far from the visible fire can still be hit. Fire reaches a home by flame, radiant heat or embers, and embers are the one that does not need the fire to be close.
That is why the Living With Fire guide asks for the first 5 feet around the house, Zone 0, to be free of combustible things. See home ignition zone.
Why it matters in Northern Nevada
Strong afternoon and downslope winds, dry fuels late in summer and fall, and pines, junipers and brush at the edge of town make embers a real concern here. Needles in gutters, juniper beside the wall, a woodpile on the deck and bark mulch against the siding are all ember catchers. See junipers and other high-hazard plants.
On a red flag day (see red flag warning) the conditions for ember travel are at their worst.
What an arborist does about it
Tree work cannot make a house ember-proof, but it can reduce the supply: removing dead limbs and needle drop above the roof, pruning branches back from the building and taking out high-hazard trees and shrubs near the walls. An arborist's walk-through points out what burns near your house. See defensible space and fire mitigation.
A fall habit worth having: clear the roof and gutters of needles and leaves, and look under the deck for stored items that could catch a stray ember. Tree work covers the part above the roof; the rest is housekeeping.
