HOLY++++!
~$660 per TREE would keep the trees ALIVE for decades with
chemical control! I am not disagreeing with the idea but why not
keep the
trees alive in this country?
Meanwhile the Smokies die.

Russ,
Thanks for posting this article. I think it is an important step
in the process to try and save the hemlock species from
extinction. It is a different approach than Will's Tsuga Search
project when individual stands are chemically treated to prevent
their deaths. I want to see a variety of approached taken to try
to preserve the hemlock. I had this discussion before, and am
wondering what criteria were used to select the trees from which
the seeds are gathered. I would in particular like to see a
concerted effort made to collect seeds from smaller isolated
populations as genetic variations that are few in number among
the general population are often concentrated in greater numbers
in these settings. Some people have said they are not worried
about sub-populations or sub species. In light of the death of
the entire species (both Carolina and Eastern), that is of
course a small concern, but while there is an opportunity to
collect seeds and at least preserve the genetic line of these
sub-populations we should be doing so.
The CAMCORE homepage is:

They have a nice page describing their hemlock seed collection
effort at:
http://www.camcore.org/projects/hemlock.php
I wonder if some type of cooperation between our organizations
might benefit the efforts of both groups?

I personally don't think the species will go extinct, maybe
locally. I think the solution is in the introduced beetles that
control the adelgid. It will take many years before evidence of
their effectiveness shows. Could they freeze the seed instead of
planting it elsewhere? Maybe they could do what they did with
the fraser fir in the Smokies, and plant up genetic banks of
trees in a nursery setting to use later when the insect is
stabilized? I just don't get why they have to go all the way to
Chile? Will is right. It seems expensive.
I wonder if anyone did any trials to see if hemlock might be
invasive in South america? If it were to escape into the natural
areas, it could cause a problem?
