Beech Bark Disease
U.S. Forest Service photo
The American beech, a dominant species in the upland forests of Pictured Rocks National Lakeshore is seriously threatened by Beech Bark Disease (BBD). Beech Bark Disease originated in Europe and was accidentally introduced to Nova Scotia around 1890, most likely in an infected European beech tree brought for a horticulture exhibit. It has been spreading slowly through the eastern U.S. ever since and was first detected in Michigan in 1990. It was discovered at Pictured Rocks in 2001. Advanced by wind, BBD has moved from east to west through the entire national lakeshore and it is estimated that 80 to 90% of the park's mature beech trees will not survive.
