Name: Sullivantia oregana - Adiantum pedatum Wet Rock Alliance
Reference: NatureServe Biotics 2019
Description: These are seepage areas along vertical rockfaces, vertical to sloped rockwalls at the base of waterfalls, and large rocks and boulders kept wet by spray from nearby turbulent waterflow (e.g., cascading streamflow or churning of plunge pools at the base of waterfalls). They have a water regime ranging from seasonally to perennially wet but a minimum duration of wetness is needed to maintain these communities. Generally, they are freshwater but water chemistry and pH can vary according to local bedrock. These are wet surfaces that range from nearly unvegetated to supporting mats of mosses and liverworts that in turn may support vascular plants and invertebrates. These areas are sometimes called "hanging gardens," or "vertical wetlands." This alliances is found in western Washington and Oregon, and likely extends north along coastal British Columbia into southeastern Alaska and potentially south along the northern California coast.
