Forest growth, removal and mortality are indicators of forest productivity. Each forest type in Wisconsin differs in productivity based on many factors such as silvics, demand for products and overall management. Recent data from the U.S. Forest Service shows that aspen, being a short-lived species, currently has the highest mortality rate of the top ten species while eastern white pine is increasing in growth and volume.
