Honolulu firefighters today continued to battle the hot spots of a brushfire in Kunia that has burned for seven days.

Firefighters today were using a portable tank that holds about 300 gallons of water. Firefighters are using pressurized hoses connected to the tank. That allows them to put water directly on hot spots, said Fire Department spokesman Capt. Kenison Tejada.

The department's helicopter is carrying water to the tank instead of making water drops on hot spots. The canopy of trees, mostly eucalyptus, makes it difficult for aerial water drops to reach ground level, said Tejada.

The portable tank was lifted by helicopter to a position on one of the ridges yesterday, Tejada said.

A tanker truck also has been stationed at the command center and staging area on Kunia Road near the Hawai'i Country Club. Hoses have been extended from the truck into the hills, where firefighters are dousing hot spots.

The fire, which is off Kunia Road and near the country club, has burned 220 acres and threatens endangered species at the Honouliuli Forest Reserve.

Tejada said the blaze is under control and not spreading, but hot spots continue to flare up.

More than 90 rare and endangered plants and animals make their home in the area above the fire, including the 'elepaio, an endangered Hawaiian forest bird.
