CASQA Releases Monitoring & Science Subcommittee Product

CASQA contracted the Southern California Coastal Water Research Project (SCCWRP) to evaluate the spatial variability of bioassessment monitoring to determine the distances that biological indices values could be extrapolated beyond observations (Report: “Spatial stream networks (SSNs): Models to estimate the spatial representativeness of bioassessment samples”).

The report is only available to CASQA members. Logged in CASQA members can view the report in the Member Library under 'Technical Reports'.
