It looks like there may be a solution to the emerald ash borer problem and the destruction of all of the trees. Michigan State University has identified a very small wasp that very specifically and selectively lays its eggs in the larvae of the borer. The young that hatch then devour the host. They feel that the wasp is so specific in its habits that it poses no other environmental threat. They will be doing some field tests in the Lansing area and hope to have it available for general distribution next year or the year after.

The latest I read from an arborist was against prophylactic removal of trees. They drew the parallel that some elms and chestnuts survived their plagues and thus we have some comeback today.
Now if we can just get the tree trimmers and firewood guys to stop, we'd be way ahead.
The biggest mill near here has stopped buying ash logs. Though they are bringing in some KD lumber from outside the area to satisfy customer demand.
The trees they removed here (on our block alone- over 45) were dead within a year of infestation. As far as I know they are not prophylactically removing trees. They barely have the money to remove the dead ones.
