One thousand acres of Sonoma County farmland likely will be added to a growing quarantine area after the discovery of three European grapevine moths near Calistoga.

Officials on Wednesday received confirmation that the insects were indeed grapevine moths, county Agricultural Commissioner Cathy Neville said Thursday.

The grapevine moth was first confirmed last September in Napa County, where the pest ruined a grape crop. Moths attacked the berries and infected them with bunch rot.

More moths have since been located, and last month the state placed 162 square miles of land under quarantine, nearly all of it within Napa County. In such areas, farmers must ensure they don't spread the moth when moving crops to market.

State rules call for all lands within three miles of an infestation to fall under quarantine. As a result, Neville said, the finds near Calistoga mean nearby lands in Sonoma County will come under restrictions for crop movement.

Last week, officials announced that a single grapevine moth was found near Kenwood, the first such insect to be confirmed outside Napa County. However, a single moth doesn't trigger a quarantine.

Shelters for Pawnee fire evacuees

Lower Lake High School, 9430 Lake St., Lower Lake, is the official shelter established for people evacuating from the Pawnee fire. It is equipped to handle animals.

The Clearlake Oaks Moose Lodge, 15900 E. Highway 20, Clearlake Oaks, is not authorized by the Office of Emergency Services but is also sheltering fire evacuees, mostly people in campers and RVs who want their animals with them.

There is an authorized Lake County animal services station in an open field at Highway 53 and Anderson Ridge Road in Lower Lake.
