DISTRIBUTION AND OCCURRENCE
SPECIES: Gymnocarpium dryopteris | Oak Fern 



GENERAL DISTRIBUTION : 
Oak fern has a circumboreal distribution [16].  In North America it
occurs form Alaska south to isolated populations in Oregon and east
across all provinces of Canada to the Atlantic Coast.  It occurs
throughout New England south to Virginia and west to Ohio.  Scattered
populations are found in the northern Midwest states of Wisconsin,
Michigan, and Minnesota, and it reaches as far south as Iowa.  Oak fern
also occurs in isolated populations of the Intermountain West and in New

found along the West Coast and in parts of Idaho and eastern Washington
[18].
