Dave, I've never known it to be the case where the choice
was "either" "or", in other words EITHER you can have a
preserved natural site OR have seed and plants in captivity
BUT NOT BOTH, unless the site is already extinct. And I don't
think it would be a matter of money either, all you need for
a seedbank is some empty envelopes and I'm sure you could
find a spare bench in an existing greenhouse somewhere
without having to build a new one over the natural site. All I'm
saying is it helps to have some seed and plants in captivity
from that site as a living insurance policy that guarantees
that particular gene pool never becomes extinct. Of course
keeping the site in existence is the top priority.
But, let's say for the sake of argument we must make the
choice. I would choose keeping the natural site. But I hope
you realize this is an artificial choice, land preservation
societies are not lacking funds because all the money is going
into collecting seeds! They lack funds because most people
don't give a damn whether the plant species exists in captivity
or the wild which is the sad truth. And all the preserved habitat
in the world is worthless if there aren't enough officers patrolling
it to prevent poaching and other destruction, and that also costs
money which the natural parks don't have. The poachers probably
have a better shot at being hit by lightning than they do being
arrested in some areas. Hopefully someday this will change, but
until it does it's up to us to do all we can to keep the species
alive by preserving natural sites and maintaining living material in
captivity.

Demetrios
