Zac,

I don't know if HWA is in AL, but
the disjunct populations of hemlock should be a high priority for
conservation.

Will-
There is a train of thought among serious conservationists that with a
finite amount of funding, it's important to choose your battles. Species at
the extent of their ranges, whether it be longitudinal/latitudinal,
elevational, moisture/temperature gradients, etc., are more sensitive to
changes in their environment, pests, etc.
In the case of Alabama, if it's pests, and they're controllable, it should be
a high priority...while everything is related to everything, reports of
dryer/hotter climate changes may not be as controllable...in the 90's on the
Kenai Peninsula in Alaska, we had a spruce bark beetle epidemic that we
(USFS) thought at first that we could control the beetle by creating
doughnut clearings around infected areas...the environmental community
stopped initial USFS efforts, in retrospect saved the USFS from some amount
of dollars...not because they had any handle on how to handle such a
problem, but because of their mistrust. The final count, something like 95%
of Kenai Peninsula spruce between certain elevations were devastated. We
need to work on the means, and action originating out of mistrust isn't
necessarily going to have positive impact.
All that said, keep up the good work you've undertaking, and the successful
results the work has brought about!
