ESA standards for large wood levelsares 20 pieces greater than 12 inches diameter and 35 feet or longer per mile. 

OW Plan (Okanogan and Wenatchee Forest Plans) standards are 106 pieces greater than 12 inches diameter and 35 

feet or longer per mile. PAC (PACFISH) standards are 20 pieces greater than 12 inches diameter and 35 feet or longer 

per mile. Note: OW Plan standards are much higher than ESA and PAC standards as well as the standard set in recent 

publication of 33 pieces/mile for streams in eastern Washington (Fox and Bolton 2007.
