Not satisfied
after MTSF, I persuaded Jani to go for a ride up the Connecticut
River to the Hatfield floodplain. There is an area I like to
visit after the water has subsided and before the mosquitoes
make visits a nightmare. Today was that day. I first shot a
silver maple with the new Nikon at the edge of the flood zone.
It just eclipses 103 feet. A cottonwood close by merited
scrutiny. It weighed in with a CBH=9.4' and a height of 110.1'.
A second cottonwood was smaller weighing in at CBH=8.1' and
height of 103.8'. Then I spotted it, the mother of all coppice
silver maples. Its height proved identical to the shorter
cottonwood; i.e. 103.8'. The trunk system showed no fusion
cracks on the downhill side. On the uphill, organic matter was
piled up to obscure the real base. Trunk fusion was evident, but
may have been seamless below the organic material piled up
against the trunk. Threading the tape around the un-seamed
downhill side and uphill seamed side led to 25.9 feet! I didn't
choose to measure the spread, but will certainly exceeds 100
feet, probably around 115. The coppice silver maple may not be a
legitimate tree for champion tree contests, but it is one
impressive assemblage of trunks, whatever their origin.
The two more 100+ foot cottonwoods
brings the significant cottonwood list to 41 trees. The Silver
Maple list stands at 37. My amazement at the number of fine
cottonwoods and silver maples as impressive trees continues to
grow. Remembering back to when I didn't think I could break 100
feet on silver maples makes me ever more conscious on how we
filter what we see and hear to fit preconceived ideas.

Dale, Howard, Tom, Lee, and other cottonwood afficianados:
Gary Beluzo and I struck it rich yesterday evening in the
Hatfield
floodplain of the Connecticut River. The borders between fields
where
there are drainages and on the cuts going down to the
Connecticut River
harbor beauties. Our first patch was devilishly difficult to get
into.
The surrounding tall burdock, thistles, etc, were 6 to 8 feet
high. A
second patch of beautiful cottonwoods was easier to access. Our
catch
for the day was as follows.
Location Girth Height
1st patch 9.0 ft est. 114.5
1st patch 9.5 ft est. 114.1
2nd patch 9.4 ft 110.1
2nd patch 9.8 ft 110.5
2nd patch 9.6 ft 118.5
2nd patch 10.1 ft 125.1
There were others that appeared to be in the
105 to 115-foot height
range and perhaps another 120. We were eaten alive by mosquitos,
so
further forays must await cooler temperatures.
The 125-footer is one sweet tree. It
becomes number 9 over 120 feet
in Massachusetts. Eventually, I'll hit 130, but it is very
apparent that
for the Connecticut River Valley north of Connecticut, that is
the
limit, remembering that these trees are growing in the absolute
best of
conditions for the species.
What are we learning from all the
roaming around searching for
cottonwoods? Well, here are some preliminary
observations/conclusions.
1. The cottonwood grows best in deep silt-based soils. Where
sand is
dominant, growth is remarkable foreshortened.
2. Cottonwoods exploit shallow depressions very well. Borders of
agricultural fields with ditches/drainages are ideally suited to
maximum
cottonwood growth. Areas that stay flooded for long periods
support
cottonwoods, but they are usually stressed and significantly lag
their
borders of fields cousins. Slopes going down to rivers are
equally good
cottonwood habitat.
3. Cottonwoods snake their way up the river valleys and into the
mountains surprisingly far, but quickly lose any competitive
advantages.
they appear mostly in very small clumps or as isolated
individuals.
4. In southern New England, the cottonwood can reach 100 feet in
under
50 years, but then slows down greatly. Throughout Massachusetts
a cap of
130 feet seems to firmly apply (we haven't quite reached it) and
in most
areas 110-115 feet seems to be the cap. Age is a big factor and
a lot
more analysis needs to be done to establish growth curves for
the
species.
5. Rapid growth in girth continues past 50 years to allow
cottonwoods
under 100 years of age to reach large size (no surprises there),
but
really huge trees are very widely scattered.
6. Maximum age or average maximum age is still unknown for the
cottonwood in Massachusetts, but the life span of 90 to 150
years
probably includes most cottonwoods. However, individuals can
attain much
older ages, so that generalizations about age are still hard to
make.
7. Cottonwoods have come of age as relates to stature. In the
Connecticut River Valley, the cottonwood is now the most common
100-foot
tree to be found outside of the places wherer white pines
commonly grow.
As is almost invariably the case, the pine assumes height
dominance, but
cottonwood is now number two.
8. Assuming that they are left to grow, in the next 50 years,
the
Connecticut River Valley will be awash in stately cottonwoods in
the 100
to 125-foot height range and 3 to 4.5-foot diameter range. They
will be
imposing in appearance. However, trees above 125 feet in height
or 4.5
feet in diameter will be very sparsely distributed.

Today was near perfect temperature-wise. A
10-15 mph wind added to the
comfort. Back to the Hatfield floodplain and the cottonwoods
Jani and I went. I
remeasured the tallest from early in the week, this time taking
more time.
Alas, I had to drop the height a few inches, but I was able to
add a couple of
real beauties. One was 10.4-ft around and 118.3 ft tall. The
other was 8.7 feet
around and 117.1 feet tall. Not bad. A third was 111.9 feet tall
and 8.8 feet
around. I then plowed through head-high weeds over to the banks
of the
Connecticut river to check out what appeared to be a large, old
cottonwood. Its
13.6-foot girth and 92-foot height confirmed it as large and it
was definitely
old. However, other cottonwoods in the immediate vicinity didn't
appear
particularly exceptional. At least they weren't worth enduring
more mosquito
bites and plowing through more 6-foot weeds.
The full list of cottonwoods from the Hatfield
floodplain past and present
follows. There are 16 trees, 14 of which have been measured
since June. The
other 2 were measured in Feb, 2002. Some of you may recall the
photo of the
huge cottonwood by Gary Beluzo. Fourteen of the 16 trees measure
30 inches or
more in diameter. Half of the trees measure are 36 inches or
more in diameter.
However, only 2 exceed 4 feet through. Three exceed 118 feet in
height. This
further illustrates that the likelihood of finding a 12-foot
circumference
cottonwood is about the same as finding a 118-foot tall one. It
will be
interesting to see if this relationship holds as the cottonwood
database grows.
I'm presently at 101 trees.

BTW, the large Conway, MA cemetary white
pine measures 140.9 feet in height and 14.1 feet in
circumference! It's one of the big ones. A near by black locust
measures 7.4 feet around and 100.8 feet in height. <Single
stem. It's a beauty.>
Well, that's my contribution for the day.
Tomorrow, back to the flood plain forest.

This AM David Graves and I went to Hatfield and Deerfield to
cruise the banks of the Connecticut River. The following list
covers today's measurements. There are plenty of trees
remaining, but my sample sizes for cottonwood and silver maple
are beginning to yield stable averages. Note the large 14.4-foot
cottonwood. It had broken off about about 45 feet up the trunk.
I didn't measure its height and I could find a vantage point to
measure the height of the 11.4-foot circumference silver maple.

Yes. I remember now. Hey, today, I spent time in the Hatfield
area on the Connecticut River flood plain. It will be a new
Rucker site. Here's the catch of the day:
Species height girth
Cottonwood 123.0 15.0
(est)
N. red oak 110.7 6.8
Green ash 107.4 6.5
Hemlock 106.1 7.3
Pignut hickory 103.3 4.0
Silver maple 92.8 11.1
Black birch 83.9 3.9
With a couple more visits, the index is likely to be around 102
or 103.
The cottonwood is on an island with other huge trees. Gotta get
there.

The limitations encountered to reaching
a much higher Rucker index for the Hatfield site is absence of
the super species white pine and sycamore. White pines do grow
on the slopes above the flood plain, but their really wimpy. The
cottonwood is the only really tall species growing there, but
there is plenty of them. So between the cottonwoods and silver
maples, the site is visually impressive.

The
largest tree we measured was an old cottonwood (102.4, 14.8). We
will eventually get the index up to 109 or 110, but without some
upland species like white pine, it won't likely go higher. We
were impressed with the silver maple (111.6, 13.0). That species
continues to to surprise us. We also measured a black willow
with a completely broken top (18.8, 48est). Yep, a whopper.
Yesterday, Susan Scott and I returned to Trout
Brook. We added a 120.2-foot American basswood that was on the
other side of the brook. Its circumference was not more than 5
feet. We re-measured on of the largest of the white pines which
we named the King Trout. Its measurements are a very respectable
(145.4, 11.6). A white pine not far away measures (11.8, 137.5).
