Thankfully CWD has not reached our shores YET Aili, but I would expect it to find its way here soon unfortunately.
Like most diseases in plants, animals and humans, globalisation has made it a great deal easier for diseases to reach even the remotest places.
Right now we have a tree disease that will most likely see the end of our native Ash trees, we lost most of our Elms in the 1960's and we are also right now losing our Horse Chesnut Trees. Our deer population is quiet healthy, but TB is on the increase and that will be the one that I think will be our greatest concern.
Chronic Wasting Disease will also have the added problem of causing great confusion over here because we have a deer species called 'CWD' Chinese Water Deer.
There is a concern about farmed Red Deer catching CWD and DEFRA have an interesting pamphlet on the subject. As someone who hunts deer for food I would be very upset to find a deer with CWD. We have a massive deer population in this country and it is a great provider of food to its hunters.
Aili how is the problem being handled in the States?
