About 1982 I planted 8000 white pine in a former pasture on the advice of my ex-forester with an OK from the DEC. They got badly weeviled. I thinned every third row and later also hit the most damaged ones which were left. I hoped to favor the few that were halfway good and a the same time expected regeneration of hardwoods and and pine that would avoid the weevils because of the protection of the older ones` shading.
The white pines in the adjacent woods are not affected by the weevil.
I have not seen a single white pine seedling?
I am getting few other species coming in.
I thought that letting in more light and space would encourage new regeneration but it does not seem to do so.
Should further thinning help?
Probably others have a similar problem. Any discussion would be appreciated.
