Laurentian mixed forest

The Laurentian mixed forest is a transitional zone in North America, situated between coniferous and deciduous forests. It is characterized by a diverse array of tree species, including deciduous hardwoods like maple, beech, and oak, as well as softwoods such as pine and eastern hemlock. This region experiences warm summers with ample moisture, leading to dense tree growth, and winters where trees shed their leaves.123

The forest is found in areas like the Great Lakes–St. Lawrence region and the upper Mississippi–Ohio region. While historically abundant in species like white pine and red oak, many have been reduced due to logging. The American elm population has been significantly impacted by Dutch elm disease. Wildlife includes common deer and squirrels, though populations of moose, wolves, and bears have declined.2
