Alsia californica is an important component of the moss flora of mostly maritime western North America. In California, the species extends primarily from Los Angeles to Del Norte counties; it diminishes in frequency roughly at the California-Oregon state line, continues sporadically northward along the coast, and then reappears more commonly in Puget Sound, Vancouver Island, and southwest British Columbia; north of California it occurs occasionally on calcareous substrates. In California, Oregon, and Washington, it usually grows in maritime habitats, quickly diminishing with distance from the coast and penetrating inland only in canyon riparian microhabitats (D. H. Norris and J. S. Shevock 2004). In British Columbia, the species extends further inland, up the Fraser River Valley approximately 150 km to just east of Hope (W. B. Schofield 1976). Ecovariant forms occur on guano-enriched rock islands immediately offshore throughout its range. Flagelliform variants, with ecostate, caducous leaves and/or fewer paraphyllia, occur in poplar stands of the Fraser Valley and occasionally in the sun-drenched upper canopies of coastal redwoods.
