Ents,
Formed in 1988 to protect extensive peat lands, the
approximately
10,000 acre Sunkhaze Meadows National Wildlife Refuge lies about
15
miles northeast of Bangor in east-central Maine. A layer of clay
over
granite bedrock and glacial deposits limits drainage and allowed
the
deep peat deposits to develop. Wet meadows and shrub thickets in
turn
cover the saturated peat. On the slopes rising up to 70 feet
above
the meadows, silty soils support mixed conifer forests (this
information and more available at sunkhaze.org).
I only had a couple hours to explore, so my observations only
reflect
one small portion of the refuge. Second growth hemlock forests
with
scattered sugar maples, bigtooth aspen, paper birch, and a few
emergent white pines cover the gentle slopes upstream of the
meadows.
That forest's open understory makes the extremely uneven surface
topography clearly visible. An adjacent ridge supports a pure
red
pine stand, and seep areas within the hemlock forest support
small
groves of northern white cedar. White cedar also mixes with the
black
spruce and balsam fir that make up the majority of the forest on
the
partially inundated ground next to the shrub bogs. Red maple and
red
spruce also grow scattered amongst the low land conifers and
above the
dense conifer regeneration. Goldthread and bunchberry persisted
into
the late fall in the slightly more open areas along the trail.

Hemlock, Eastern 9'10" 85.0'
Larch, American 2'10" 67.2'
Pine, Eastern White 7'8" 101.7'
Pine, Red 4'9" 95.4'
Spruce, Black 4'4" 87.8'
Spruce, Black 4'0" 89.0'
Spruce, Red 4'5" 69.0'
White Cedar, Northern 3'11.5" 62.1'
The few quaking aspen grow in the wetter conifer forest. The
large
eastern hemlock is one of a pair of remnant trees adjacent to a
maintained clearing. The larch was the only individual present
in the
area, although they are apparently common in other parts of
Sunkhaze.
The black spruce approach national champion size, which may
reflect
the lack of attention the species receives or may result from
hybridization with red spruce (which is apparently common in the
area).

Jess:
There are a number of black spruce with bigger cbh in the
Boundary Waters,
but I never thought about measuring them for possible champion
status. I
didn't realize the national champion was so small until you
pointed it out.
The big ones grow on upland sites where they are not constrained
by
flooding and nutrient-poor soils of the acid bogs.
