G616 Arctic Gravel Floodplain Vegetation Group
Type Concept Sentence: This group includes sparsely vegetated rocky floodplains, with little soil alluvium. Nonvascular cover may be very low to absent, and vascular cover is low.
Common (Translated Scientific) Name: Arctic Gravel Floodplain Vegetation Group
Colloquial Name: Arctic Gravel Floodplain Vegetation
Hierarchy Level: Group
Type Concept: This type includes sparsely vegetated rocky floodplains, with little soil alluvium. Nonvascular cover may be very low to absent, and vascular cover is low.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Placement of this type is problematic. The environmental setting is atypical for the formation. If the sparse vascular vegetation is more typical of riverine wetland habitats, perhaps the group should be moved to 2.B.6. ~Temperate to Polar Freshwater Marsh, Wet Meadow & Shrubland Formation (F013)$$. But if the habitat is more often dry and these rocky floodplains are similar to upland rock outcrops, then placement in this formation may be good.
