SOME EFFECTS OF LOGGING AND ASSOCIATED ROAD CONSTRUCTION ON NORTHERN CALIFORNIA STREAMS

THE EFFECTS OF LOGGING AND ASSOCIATED ROAD CONSTRUCTION ON FOUR CALIFORNIA TROUT AND SALMON STREAMS WERE INVESTIGATED FROM 1966 THROUGH 1969. LOGGING WAS FOUND TO BE COMPATIBLE WITH ANADROMOUS FISH PRODUCTION WHEN ADEQUATE ATTENTION WAS GIVEN TO STREAM PROTECTION AND CHANNEL CLEARANCE. THE CARRYING CAPACITIES FOR JUVENILE SALMONIDS OF SOME STREAM SECTIONS WERE INCREASED WHEN HIGH TEMPERATURES, LOW DISSOLVED OXYGEN CONCENTRATIONS, AND ADVERSE SEDIMENTATION DID NOT ACCOMPANY THE LOGGING. EXTENSIVE USE OF BULLDOZERS ON STEEP SLOPES FOR ROAD BUILDING AND IN STREAM CHANNELS DURING DEBRIS REMOVAL CAUSED EXCESSIVE STREAMBED SEDIMENTATION IN NARROW STREAMS. OTHER ASPECTS OF LOGGING ON ANADROMOUS FISH PRODUCTION ON THE PACIFIC COAST ARE DISCUSSED. /AUTHOR/
