DISTRIBUTION AND OCCURRENCE
SPECIES: Arctostaphylos uva-ursi | Bearberry 



GENERAL DISTRIBUTION : 
Bearberry is a widespread, circumpolar species [111].  In North America,
it grows from the northern half of California north to Alaska and across
Canada and the northern United States to New England and Newfoundland.
Its range extends south in the Rocky Mountains to New Mexico.  In
eastern North America, it extends south along the Atlantic Coast to New
Jersey and in the Appalachian Mountains to Virginia.  Rare, disjunct
populations occur in Georgia [59,117,152].

Most infrataxa occur in the Rocky Mountains and are widespread.
Distribution of the forms is as follows:

    Forma adenotricha is common in the Rocky Mountains but absent in the
Appalachian Mountain region and both Coasts.  A closely related taxa is
found in the Sierra Nevada [117,149].  
    Forma coactilis may not be present in Alaska; it is most abundant
on both Coasts.  It is found farther south along the Pacific Coast and
in the Appalachian Mountains than the other forms [117,149].  It is the
primary form in Ohio and New England [15,125].  
    Forma longipilosa is absent from the Appalachian Mountains and very
rare on both Coasts [117,149].  
    Forma stipitata grows only in the Rocky Mountains and far West
[117,149].  
    Forma uva-ursi extends the farthest north in the Arctic and is
circumboreal through Eurasia [117,149].
