ENTS,
On Wednesday, John Knuerr and I headed
to Dunbar Brook in Monroe State Forest to model the bulky Dunbar
Brook hemlock as part of Tsuga Search-New England. I'll give
fuller details when I return from the Daks. In a nutshell, the
tree cubes out to 721 cubic feet of trunk volume. The tree is
116.3 feet tall to a fairly stubby dead top. I would imagine the
tree was at one time 122 to 126 feet tall. The CBH is 12.8 feet
and the trunk has a very slow taper. I modeled this tree with
the Dendrometer a couple of years ago and overshot the volume
considerably. I would expect that the reticled volume by John
and me is very close. Using the base diameter of 4.55 feet and
treating the tree as a simple cone, the volume would be 629
cubes. The actual volume of the old-growth hemlock form (721)
can be expected to be from 10% to as much as 20% over the cone
volume from the base (above root swell). The 14.6% overage in
this case is right in the middle.
BTW, John Knuerr is still thinking
of a better ENTS name for the tree.
