Is Elm making a comeback or is it just a fairytale?

[Gary Prentice]

I remember doing a talk on DED in 1979

There was an innoculation that I think Brighton used. Can't remember the name of it. Useful I'm not.

 

Something along the lines of "ceratotex" although I'm not sure it was too successful. Halifax council tried it on some wheatley's near the town centre for a couple of yrs, but I suspect the micro-climate had more to due with the delay in infestation, than the chemical.

ialso see a lot elm where i work in the n.west! i think a lot is sucker growth, but there are also a number of more matiure elms which survived dutch elm disease about.

Interesting - my understanding (which may well be wrong, I'm making no assertions) is that U glabra is to some extent protected from infection by the form of its bark - i.e. it's less attractive to the female beetle - but once infected, succumbs relatively quickly.

 

Natural selection article for sciency types - I found it very interesting:

Hi H

I've never seen ref to that theory, can you remember where you read it?

 

Interesting article on natural selection, I had seen Endler's work before, but that was a study on the Bauer bird if memory serves correctly.

but there are also a number of more matiure elms which survived dutch elm disease about.

 

I have found this also, there are quite a number around here in exposed locations, I had a theory that being on the coast, the constant prevailing westerly wind hampered the beetles flight capability??

possible! i have also taken a few dead ones down in the last couple of years which had beetle gallery formations under the bark, not sure if DED killed them though, or nearby developments.

i would go along with that, there is some nice street tree elms in a high part of bridlington (on the east coast)

I can't remember where originally heard/read it, but I found this in The Elms: Breeding, Conservation, and Disease Management By Christopher Paul Dunn

Where on earth did you find that?

 

Excellent
