How did European mountain ash ringspot-associated virus get here and what impact will it have?
We don’t know how the virus got here or where it originates. Little is known about the virus in general, until further studies are undertaken we don’t even know what the severity or full effects will be.
We do know that affected trees grow more slowly than healthy trees and might suffer gradual dieback after a few years.
