ENTS:
Today Susan Scott and I slugged around
in the snow to get a better documentation of the trees growing
in a park on the Green River flood plain in Greenfield, MA.
Soils are clay-silt. Cottonwoods and sycamore were initially our
main quary, but we quickly realized that we should broaden our
measurement focus. The catch of the day is as follows:
Species Height Circumference
Sycamore 128.7 8.9
Sycamore 121.8 6.0
Sycamore 110.0 8.2
N. Red Oak 116.9 11.1
Green Ash 90.2 8.2
Pignut Hickory 106.8 6.2
Shagbark Hickory 112.6 5.6
Cottonwood 107.8 7.8
Cottonwood 102.1 10.5
There are sufficient species to give a
10-species Rucker index. We'll finish next time. The six we got
yielded an index of 110.5. A 5-species Rucker index yields
114.56.
Species left to measure include white pine,
American beech, black willow, and sugar maple.
Our measurements of the tall sycamore were
particularly satisfying. On the downhill, across the stream
measurement, I got 128.6. From the hill above the sycamore, I
got 128.7. Susan got 128.44 from upon the hill. So 3
measurements involving 2 set of equipment yields measurements
differing by only 3 inches.
Susan is becoming quite proficient. She is
destined to make many excellent contributions for ENTS.
