ENTS,

It looks like our president has help and a competitor, but we cannot
have too many people saving hemlocks. I just saw " Hemlock Healers "
ad on TV and looked em' up. Like Appalachian Arborists they do work
for the NPS and the owner of Hemlock Healers was a forestry Technician
for the GSMNP. I bet he and Will know of each other.

James/ENTS,

Have there been individual hemlocks within the devastated areas that
have shown resistance to HWA and survived?

Gary,

Not that I have seen. It seems that the old growth hemlocks succumb to
the adelgid faster than the younger trees. Maybe it is because of
their slower growth. At first that would seem odd. Growing takes
energy and nutrients. But faster growing trees foliate more as they
grow which may help them outpace the adelgid for awhile. I have
noticed saplings alive in the understory while all of the canopy trees
are dead. But eventually they to will succumb.

In many forests if a few hemlocks are green among a majority of dead
and dying trees they have been treated. I have seen no evidence of
resistant hemlocks.

Gary,

Not that I have seen. Jess and I came across green trees in the course of
the Tsuga Search Project but fallen twigs and those visible were covered in
HWA.

I would expect them to defoliate again (they had re-flushed new twigs after
the first defoliation) and die as they run out of buds/energy.
