ENTS,
This past week I discovered a small population of Liriodendron
on the edge
of Russell Pond that were impressive trees this far north. The
largest was
a 11.8' (girth) tulip poplar right on the edge of the pond.
Several other
trees measured 10.9, 10.1, and 9.8 feet in girth. Heights ranged
from only
74.2 to 115.4'. The following day Ray Weber and I drove through
Granville
and marked many locations for future visitation (perhaps today
or tomorrow).
The Granville Gorge looks especially promising. I also measured
a tulip
poplar in the middle of someone's front lawn on the way back on
North Loomis
Road in Granville that measured 14.2 feet in girth, one of a
handful of
large, open-grown tulip poplar in Massachusetts.
On Friday I visited a site in Whately, MA (thanks to clues given
by Russ
Richardson and some detective work at the Whately Town Hall) to
look for the
northern edge of Liriodendron in Massachusetts (Connecticut
River Valley).
After several hours of driving and walking I finally found the
site. Here
is the description:
The 150 acre site is a working forest, about 1 mile west of Rte
91 in
Whately, MA, and consists of a small stream valley on the east
and a wall of
ledge with upland habitat to the west. Recent (2005-6) and
previous (1984
and before) logging roads and stumps exist. I was VERY impressed
with the
forestry being practiced on this site by Baystate Forestry
Services.
Although there are very few large trees (most are 0-1.5' DBH)
the diversity
is high (I counted over 35 species) and the growing conditions
appear to be
excellent based on the height/diameter ratios of many of the
species extant.
In the small stream valley I found TULIP POPLAR, American beech,
black
birch, yellow birch, sugar maple, red maple, hemlock, black
cherry, white
oak, northern red oak, scarlet oak, white pine, white ash, and
green (or
black) ash.
In the upland area in and around the ledges I found primarily
chestnut oak,
white pine, white oak, hemlock, red maple, northern red oak, and
a few red
spruce right at the upper edge of the hill. The aspect for most
of the site
is east-southeast.
I was primarily interested in the Liriodendron (I measured all
of the trees
that I found):
Girth (Feet) Height
(Feet)
5.10 94.9
3.92 98.1
4.87 105.5
(Maximum Height for species on site)
3.95 101.9
6.31 103.2
5.17 100.3
4.50 90.8
4.45 86.2
6.25 103.5 (Maximum
girth for species on site)
4.86 96.0
4.72 102.0
4.25 94.5
2.60 72.0
3.30 88.5
4.11 96.0
3.93 94.5
4.56 100.5
4.50 100.2
I did get an opportunity to measure several other species while
I was there.
This is NOT representative of all the species present nor are
the
measurements necessarily representative for species measured,
although I did
try to measure specimens that looked representative on the site.
Species Girth Height
BigTooth Aspen 6.20 -
Black Cherry 3.60 70.5
Black Birch 2.97 78.9
Northern Red Oak 4.75 92.6
Red Maple 3.78 74.1
White Pine 5.90 102.4
White Pine 5.67 103.8
White Pine 10.15 108.3 (Largest
WP on the site)
As you can see this is a fairly young forest although all but
several of the
tulip poplars had fruit capsules. Most of the trees appeared to
be of the
same cohort although I didn't do any coring while I was at the
site this
first time. There
are indications of repeat harvesting of small
numbers of trees, there were stumps in various stages of
decomposition and
most of the stumps had anywhere from 65-105 growth rings.
This site is significant in that it is the most northerly site
that I have
documented in Massachusetts so far. Also, none of the published
distribution maps that I have reviewed, including one detailed
one from the
Department of Agriculture (by county) show Liriodendron in
Franklin County
(the county farthest north in the Massachusetts Connecticut
River Valley.
Now Bob Leverett and I have Liridendron measurements from 42
degrees 05
minutes (Agawam and Granville on the MA/CT state line) to 42
degrees 26
minutes (Whately, MA).
This week I plan to explore from Whately north to the Vermont
border and see
what I can find, weather permitting. The Liriodendron Search
Project goes
on!
