DISTRIBUTION AND OCCURRENCE
SPECIES: Acer circinatum | Vine Maple 



GENERAL DISTRIBUTION : 
Vine maple occurs in the Pacific Northwest.  It ranges from the
Cascade Mountains to the coast and from southwestern British Columbia to
northern California [26].  In Washington and California, vine maple may
extend down the east side of the Cascade Mountains along canyon bottoms
and moist slopes but is confined almost entirely to the west side of
the Cascades in Oregon [61].

HABITAT TYPES AND PLANT COMMUNITIES : 
Vine maple is typically an understory shrub found in both seral and
climax Douglas-fir (Pseudotsuga menziesii), western hemlock (Tsuga
heterophylla), western redcedar (Thuja plicata), Port Orford-cedar
(Chamaecyparis lawsoniana), Sitka spruce (Picea sitchensis), and Pacific
silver fir (Abies amabilis) forests on the west side of the Cascades
[15,18].  On the east side of the Cascades, vine maple occurs on moist
bottoms in ponderosa pine (Pinus ponderosa) forests [61].  The western
hemlock/vine maple/western swordfern (Polystichum munitum) plant
association is common throughout the Olympic, Cascade, and Coast Ranges
of Oregon and Washington [26].  Vine maple sometimes dominates or
codominates talus slopes with Sitka alder (Alnus viridis ssp. sinuata)
[18].
