CEGL005065 Juniperus communis - (Quercus rubra) / Juniperus horizontalis - Arctostaphylos uva-ursi Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Common Juniper - (Northern Red Oak) / Creeping Juniper - Kinnikinnick Shrubland

Colloquial Name: Common Juniper Rocky Krummholz

Hierarchy Level:  Association

Type Concept: This juniper shrubland type is found in Michigan, United States, and Ontario, Canada. Stands are found on exposed, igneous bedrock substrates. In Michigan, stands are found at higher elevations in the Porcupine Mountains, where exposure to wind and cold has stunted the vegetation. The shrub/scrub canopy varies from open to closed. In Michigan the scrub layer includes stunted Quercus rubra and Juniperus communis. The dwarf-shrub layer contains Juniperus horizontalis and Arctostaphylos uva-ursi. This type needs further characterization.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: It is not known whether the Ontario stands resemble the Michigan stands sufficiently to warrant keeping them in the same type [see Bakowsky and Lee (1996)]. This type needs further characterization. It probably occurs along the northern shore of Lake Superior in Ontario, and possibly along the northern shores of Lake Huron, in the north channel and Georgian Bay areas.
