This phytosociological study, carried out according to the Braun-Blanquet method and
supported by cluster analysis, describes Walter's zonobiomes along the North American
Pacific coast between British Columbia (Canada) and Baja California Sur (Mexico).
Fourteen floristic associations have been identified and each is characterized by a unique
floristic combination, a distinctive geographical range and particular bioclimatic conditions.

This phytosociological study, carried out according to the Braun–Blanquet method and
supported by cluster analysis, describes Walter's zonobiomes along the North American
Pacific coast between the California–Oregon state border and Alaska (USA), including some
interior zones of British Columbia and the Yukon Territory (Canada). Twenty two floristic
associations are identified and each is characterized by a unique floristic combination, a
distinctive geographical range and particular bioclimatic or edaphic conditions.
