Wasco County and fire districts within it will be implementing a county wide burn ban effective on Wednesday.  This ban includes open burning such as yard debris and burn barrels and is intended to prevent wildfires.  Hood River County plans to implement their seasonal burn ban July 1.  Fire managers welcome the recent rain, but caution landowners that warm temperatures and dry periods quickly dry fine vegetative fuel, making it receptive to fire starts.  Fire burning in these fine fuels quickly spreads to both live vegetation and larger fuels which have low fuel moisture due to underlying long-term drought conditions.  The Oregon Department of Forestry says any landowner who has burned this spring should revisit their burn site to ensure there is no fire or heat remaining, which could spread to adjacent fuels as seasonal weather returns.  The Dalles Unit forester Kristin Dodd says they are concerned that recent rain will give landowners a false sense of the risks involved with burning at this time.  Alternatives to burning, such as chipping or disposal at a local landfill are encouraged.  Counties and local fire departments may have additional restrictions in place.
