MI’s Changing Forests: Columbus Dispatch
At one time, the forest lands of northern Michigan and the rest of the Upper Midwest were cutover scrublands. The initial stage of logging left the land scarred, prone to massive fire and pretty much devoid of use. But forest planners successfully implemented a long-term project that reforested the region. The return of bear, moose, elk and wolves to the region are testament to this success.
One challenge, however, is that many of these reforested areas are nearing the end of their natural lifespan. And the species that populate these forests are, for the most part, not original or even sustainable over the long term. So scientists have been studying what will happen as these forests transition into their next stage of life. The Columbus Dispatch has a recommended article on this topic:
New research on evolving Midwest forests underscores the role that trees play in trapping carbon dioxide and how fragile this storage system is.
A team of biologists and foresters at Ohio State University, Indiana University and the University of Michigan say the aspen and birch that dominate forests of the northern Midwest are reaching the end of their lifespan.
But the researchers predict that the white pine, red oak and red maple trees growing in the forest understory and poised to take over will absorb even more carbon dioxide, the main ingredient in global warming.
“The forest will be more diverse and the canopy more complex, with a leaf distribution that can process light more efficiently,” said Peter Curtis, chairman of evolution, ecology and organismal biology at Ohio State.
Curtis and his colleagues base the prediction on nearly 10 years of work at the University of Michigan Biological Station, near Pellston, Mich. The scientists recently described their findings in the journal BioScience.
