Annual estimates of the abundance of naturally-produced spawners for each stratum.
The Mid-Coast biogeographic stratum includes all Oregon coastal watersheds (except Sutton Creek/Mercer Lake) from the Salmon River in the north to the Siuslaw River in the south. There are a total of 6 independent populations and 1 dependent population group in the stratum. The dependent population group consists of 23 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.
