Apparently OPM have been found by the forestry commission locally to us in Long Eaton.. Doesn't look like they have updated their map, but if that is the case I guess they have well and truly escaped from London..

Bugger that's further from London than us. Unless they went up the M1, like.

Wonder at current advancement how long before its the whole UK?

 

 

100yrs or a less than a  decade?

Will it find it is warm enough as you go further north?

I think that'll be last years map. I don't think they live report.

 

Be interesting to know if it's an isolated case and wether it's just one nest or many.

 

Every year there are a number of isolated infestations that have come in on new planting, these ones normally get erradicated quite quickly.

[Alinicoll]

If you go into the layers tab on the map it shows the 2019 map of eradicated infestations following an exercise tracing all imported oaks. That shows how many eggs are still getting in on young trees.

 

This demonstrates how unusual it is for a population to establish from an import.

So its seems its   all over UK even scotland but the outliers have being kept from  spreading or just haven't spread?

So is that due to human intervention / eradication or some other reason as surely some isolated trees  & woodland will be missed outside main the zone?

 

 

[Alinicoll]

The large number of outliers from 2019 were eradicated by the Forestry Commission. Where outbreaks are found in the pest free zone, the Forestry Commission are very effective at dealing with them.

 

I think really what these outliers show is that even if a tree or trees are brought in with OPM on, it’s difficult for an isolated population to establish.

I checked with the council and they were found on mature trees and not recent plantings. I can't believe this is an isolated case..

Interesting, be interesting to see what they do.
