“Acts of creation are ordinarily reserved for gods and poets. To plant a pine, one need only own a shovel.”

Those were the words of Wisconsin’s most prominent conservation expert, Aldo Leopold, who authored the famous book, “A Sand County Almanac” among his many achievements.

This month, everyone in Wisconsin will have the chance to follow Leopold’s advice – even if in a small way, because many small efforts can add up to a prominent positive impact on Wisconsin’s trees and forests.

Oak decline and mortality continue to be an issue in Wisconsin, and because of the recent droughts and spongy moth outbreak, we expect these impacts to become more widespread this summer.

Forest decline is the progressive loss of tree and stand vigor and health over several years without obvious evidence of a single causal factor. Typically, trees die in a scattered fashion across a large area over several years. The additional stress from defoliation can result in pockets of heavy oak mortality, particularly on dry, sandy sites and steep, rocky ridges and hills.
