Diablo Canyon power plant site ecological study Quarterly Report no. 17: July 1 - September 30, 1977
During the quarter a total of 38 random 30-m2and 152 random 1/4-m2 subtidal stations weresurveyed. Red abalone, Haliotis rufescens,densities remained very low. There was a continueddecline in densities of giant red seaurchins, Strongylocentrotus franciscanus, inDiablo Cove as well as the North Control area.The annual shore census of bull kelp, Nereocystisluetkeana, revealed the lowest number of plantsin the surface canopy in Diablo Cove since 1973. The subtidal station data supported this observation.Sea otter, Enhydra lutris, observations werecontinued. A small group of otters continuedto raft in the Cove east of Lion Rock. Someof these otters probably forage as far south asSouth Cove.The survey of 11 random intertidal stationscompleted our Upwelling sampling effort. (16pp.)
