Cutting All Ash Trees Not 'Proven' To Stop Ash Borer
The mass removal of ash trees is not a proven method for stopping the spread of the emerald ash borer...
That word from a Minnesota agriculture spokeswoman comes as the Gopher State plans to use stingless wasps to destroy the ash borer population there. Liz Erickson of the MDA says a test release of wasps in Houston County hasn't lasted long enough to show that it works. The city of La Crosse is talking about cutting down all ash trees in certain parks, to keep the ash borer from killing the trees. The park board may vote on the clear-cutting plan tonight.
