I recently read this thesis:
produced by Tom Litwin in 1986, discussing the changes in Sapsucker Woods in 
both avian type and foliage type, over the hundred years up to that time.

Amazing that grazing, lumbering, and fire have all passed through SSW prior to 
its ‘sanctuary’ days.
The charted changes in nesters (Canada Warblers were once frequent!) is very 

My only point here is that Tom says early on something to the affect that there 
is a difference between ‘conservation’ and ‘preservation’ and that distinction 
had never hit home before so clearly.
Not to bend the Latin (and PIE) roots too far, but ‘con’ (from Latin ‘cum’ with 
or together) and ‘serve’ (‘ser’ protect) is not the same as ‘pre’ (beforehand) 
and ‘serve’.
Protecting together, as John C eloquently described, is not the same business 
as protecting the same static thing forever.

I finally grasped why the south side of the SSW is so barren of lower tier 
breeders, after looking at Litwin’s historic maps of the woods.
Frankly, I prefer the north and east for diversity; the south high closed 
canopy has its interesting but quite different residents (thrushes, tanagers, 
barred owl, pileated et al., high canopy warblers in migration, and ovenbirds 
to give one forest floor denizen his due.)

The occasional cutting, as horrifying as it seems, breathes and welcomes new 
life into the tired old forest, when done intelligently and in moderation.
I would like to think that keeping an eye on the DEC efforts is worthy, but 
that DEC is not rapacious in intent.

HI Dave,

    It still surprises me that even among environmentalists, biodiversity is 
still a matter of contention. There are ecological reasons to support 
biodiversity, often thought to enhance the mega goal of biostability.
