Description: |
DISTRIBUTION: The CWHvm2 occurs at higher
elevations, above the CWHvm1. Elevational
limits range from approximately 650-1000
m in the south to 450-800 m in the north.
It grades into the MH zone above.
CLIMATE: The CWHvm2 has a wet, humid
climate with cool, short summers and cool
winters featuring substantial snowfall.
Compared with the submontane variant, the
CWHvm2 has cooler temperatures, shorter
growing seasons, and heavier snowfall, with
snowpacks persisting throughout the winter.
VEGETATION: Forests on zonal sites are
dominated by Hw, Ba, and, to a lesser extent,
Cw, Yc, and Hm. The latter two species become
more common with increasing elevation and
wetter sites. Major understorey species
include Alaskan blueberry, five-leaved bramble,
Hylocomium splendens, Rhytidiadelphus loreus,
and Rhytidiopsis robusta.
