Prairie Creek in Redwood National and State Parks is the site for this study of the life history of silver [coho] salmon, king salmon, and steelhead trout. The author observed spawning runs, located and sampled redds, captured and counted young from a natural redd of each species and from planted eyed eggs of each, and monitored population fluctuations. This paper reports the results of the first season. The test section showed that spawning is not successful where water velocity is significantly less than in normal habitat. The chief limitations on survival of fry are food competition and predation (largely by salmonids of the same or other species).
