COSEWIC Assessment Summary and Status Report: Cucumber Tree, Magnolia acuminata
Assessment Summary – April 2010
Reason for designation
This forest canopy species of the Carolinian zone of southern Ontario is present as a series of small populations in a region of highly fragmented forest cover. Its total Canadian population consists of about 200 trees with most of the sites having only a few mature reproductive individuals. Several sites only have single trees without evidence of regeneration, which makes the species highly susceptible to certain catastrophic events, such as ice storms. Its habitat is under continued impact from local disturbances and loss of forest area.
Designated Endangered in April 1984. Status re-examined and confirmed Endangered in April 1999, May 2000, and April 2010.
