Does anyone know if some of the grove of old hemlocks along the
Falls Trail (off the Blue Ridge Parkway below Craggy Pinnacle)
treated with imadacloprid? I ask this because when I visited
there a few
months ago, the trees seemed to be in pretty good health. One
friend told me that he's seen a marked improvement in the
the hemlocks there. This makes me suspect that the trees (at
ones closest to the trail) have been treated. Having seen the
state of the hemlocks just a few miles away (in some cases just
hundred yards away), I'm suspicious.
At any rate, perhaps there should be some way of posting a list
that have been treated so that others don't go and repeat

there was a release of Psasajiscymnus tsugae (sp.?) there for
the past two
years. I have asked Linda Randolph, the responsible official, to
treating at Douglas and Walker Falls with Zenith, and her reply
already did a beetle release". Hopefully, if enough folks
National Forest and demand that at least a small grove be
chemically, just in case (since predator beetles haven't worked
Forest Service will preserve some of that amazing grove.
As an aside: I came across a grove of hemlocks at Shinbone Creek
Mitchell County last week that has trees that rival those at
The overall forest is not as impressive, but individuals are.
This grove is
also in good shape and deserves at least a beetle release.

Josh and ENTS,
Quality Forward, an organization here in Asheville concerned
environmental issues and particularly HWA, contacted the USFS
and volunteers in hand to treat parts of Douglas Falls. Their
refused due to the "success" of the beetles. When
asked for results of a
survey or study regarding the beetles, the response was
"Look for yourself".

I have to say, from looking at the grove myself...the trees
pretty healthy a few months ago. I haven't seen them this
though. And one friend who does frequent the area tells me that

My own suspicion is that some enterprising folk have visited the
and treated the hemlocks with imadacloprid.

The trees look better? Hmmm. Very interesting. They must have
used those new OTT beetles. The FS people must be gloating over
their apparent success.

If the Forest Service is having success with beetle releases,
then we should
all be happy. What I have seen however is that the populations
predatory insects decrease dramatically from one year to the
next. In most
cases there is no examples found from the previous years release
following year. If the predatory beetle in this case can
population numbers the following year and spread to nearby
We will need to wait and see.
