A3779 North Pacific Nonvascular Rock Vegetation Alliance
Type Concept Sentence: Barren and sparsely vegetated landscapes (generally <10% vascular plant cover) of steep cliff faces, narrow canyons, and larger rock outcrops of northern California to southeastern Alaska.
Common (Translated Scientific) Name: North Pacific Nonvascular Rock Vegetation Alliance
Colloquial Name: North Pacific Nonvascular Rock Vegetation
Hierarchy Level: Alliance
Type Concept: Barren and sparsely vegetated landscapes (generally <10% vascular plant cover) of steep cliff faces, narrow canyons, and larger rock outcrops of northern California to southeastern Alaska.
Diagnostic Characteristics: Too little is known about the floristics of these habitats at this time to describe diagnostic criteria.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This alliance is a placeholder based on ~North Pacific Montane Massive Bedrock, Cliff and Talus (CES204.093)$$ and includes active volcanic rock and cinderlands. Few studies have been conducted on the floristics of volcanic substrates of these habitats and may warrant creation of a separate alliance.
