Abstract:

Communities of mosses and lichens below high water mark on the Salmon River in Idaho are viewed as distinct associations. These zones may be as much as several meters in depth. Based on the species present and on fluctuating water levels, four zones are are found. Results from paired transects indicate that stability of the substrate, force of the current, and distance above the low water level determine species dominance. Compared to the headwaters, the lower reaches of the river have more favorable conditions for growth of mosses and lichens and for development of zonation patterns.
