Annual estimates of the abundance of naturally-produced spawners for each stratum.
The North Coast biogeographic stratum includes Oregon coastal watersheds from the Necanicum River in the north to Neskowin Creek in the south. There are a total of 4 independent populations and 1 dependent population group (DPG) in the stratum. The dependent population group consists of 9 separate dependent populations.
The trend in adult abundance is presented for all strata. Analyses for other criteria are available for the individual populations contained within each stratum.
