Re: DNA testing

I had a site where the council ecologist was certain there were native
black poplars and ultimately we arranged for a DNA test through one of our
Ecologists. I seem to recall they were based at Chester Zoo. I'll see if I
can find out.

It was a waste of everyone's time but at least I got to say "I told you so"
at the end because they were obviously hybrids.

Wayne - the British 'native' black poplar is the sub-species Populus
nigra ssp. betulifolia - quite distinct different from American
cottonwoods, such as P deltoides, with which it was crossed back in the
19th century giving rise to the host of hybrid black poplars, which now
vastly outnumber the native tree.
The native tree is considered to be something of a rarity in the UK,
although it is now being propagated quite widely.
Dr. Fiona Cooper has written a very informative book on the tree [ISBN
1-905119-05-4]

I am just beyond the southern native (but not necessarily historic) range
of our native black cottonwoods here on the west coast of the US. In the
wild they seem well-behaved. They remind me of aspen, but grow almost to
the sea. A few have been reported in the mountains of Baja California,
Mexico.

Does anyone have any experience of DNA testing to confirm the presence
of
native black poplars?

Specifically what samples were required and where the testing was
completed?

Thanks in advance
