Joe, I would tend to disagree with you. Simply because the forest industry has repeatedly mutilated the term forest health does not mean that the concept is invalid. Just because the concept is not easily quantifiable does not mean it is not a scientific concept. Not trying to define the idea of forest health in scientific terms, is simply ceding it to the forestry industry to use as they will. Forest health is an ecological concept. It is a scientific concept and better and clearer scientific definitions need to be developed to serve as a counterweight to forest industry arguments that practices like clear-cutting and high-grading promote forest health. To counter the idea that cutting old growth forests promotes forest health because younger forests may have a higher bird species diversity. These are my thoughts on the subject.

Lee,
I'd like to suggest that the term "forest health" should be avoided- it's not
a scientific concept. Proponents of different forest policies can all claim
that their policies maintain productivity and species richness. Too often the
debate stops there.
To solve the forestry debates, we need much clearer use of language and solid
science and the recognition that forest policies are a combination of:
a.. biological and ecological science- the only fully rational and testable
concepts which should have little debate
b.. economics- a social science, often derided by economists themselves as
the "dismal science"- not a strong pillar in forestry debates because too many
benefits and costs are not counted
c.. politics- because various forest policies will benefit some
socio-economic classes and hurt others- the underlying politics is almost
always avoided in polite discussions, thus greatly limiting the true value of
those discussions
d.. aesthetics- because the decision to cut some trees/forests may or may
not consider aesthetic values- such values are not correlated well with the
other considerations and there is no right or wrong aesthetics
Forestry establishments often claim THEIR polices will lead to improved
forest health without a sound case being made on those above issues. Based just
on some vague sense of "productivity" and "species" richness, on some level
they may be right- which may appear to support their policies which can not be
supported on a fuller consideration of all relevant values.
Thus, I find the entire concept of "forest health" dubious and destructive
regardless of who defines the term. Better to throw the term out and look
deeper into the full range of considerations relevant to what we're trying to
get at when we're thinking about "forest health".
Bob said, "While at Robinson, we talked about the distinction between forest
health as seen through the eyes of the timber specialist versus the forest
ecologist. Lee provided the group with a succinct definition of forest health
that stressed balance and diversity. I will ask him to repeat his definition
for the benefit of all Ents. Lee puts the subject of forest health into
perspective, something the timber community cannot objectively do."
The ancient problem is that most "timber specialists" are trained to see the
forest as a factory- while the forest ecologist abhors the idea of the forest
as a factory. Whatever we think we mean when we think of forest health has got
to be something that will make both sides unhappy because their vision will be
seen as simplistic- the goal is to come up with a new term that is a superset
of the concept of "forest health"- richer by orders of magnitude, in such a way
as to obtain the goals of both sides- a fusion which must be found, but like
nuclear fusion, a most difficult challenge.

Bob:
Excellent report. I just arrived home in MN after stopping in PA Sunday
evening and at my brothers house in WI Monday night. This is not exactly the
frigid land you mention--it was over 70 degrees here today and yesterday. We
are in an unusual November heat wave, and have not had snow like that I drove
through in PA on the way out to MA.
Here is my definition of forest health that you requested:
A forest is healthy as long as it maintains the productivity and species
richness (all taxonomic groups) of the pre-European settlement forest over
time.

Introduction
The time has arrived for the 2008 western Mass ENTS
rendezvous to be entered into the ENTS record book. Let it be noted that the
rendezvous officially commenced on Oct 30, 2008 and ended at the close of
November 2nd. We had an informal, if not subdued, gathering, but the event
produced some highly significant results. The report below covers the details
of the 2008 rendezvous. However, before discussing the particulars, let me note
that for October 2009, we are considering switching to <?xml:namespace prefix =
st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Cook Forest State Park
for our ENTS fall gathering. Details will be forthcoming.
