'Why You Can't See the Forest for the Beech' at Next Clarkson University Science Cafe

"Why You Can't See the Forest for the Beech" will be presented by Associate Professor Mariann Johnston of SUNY College of Environmental Science and Forestry's Wanakena campus at the next Clarkson University Science Cafe at 7:15 p.m. on Tuesday, Sept. 13, at St. Lawrence University's Pub 56, between Hulett and Jencks Halls on Avenue of the Elms in Canton, N.Y., and at 7:15 p.m. on Wednesday, Sept. 14, at the St. Lawrence Valley Roasters & Jernabi Coffeehouse, 11 Maple St. in Potsdam, N.Y.

Mariann JohnstonA walk through the woods of the North Country yields an unparalleled view of beech sprouts, whose small but plentiful stems fill the forest understory with leafy green in the summer, and snap the unwary traveler in the face during those cold winter hikes. But it wasn’t always this way! What has happened over the last century to convert this once-majestic forest tree to an invasive shrubby thicket, and what is the impact on the biodiversity and functionality of our northern hardwood forests? Join Johnston for a discussion about beech bark disease, the insects and fungi that cause it and current research efforts on the subject.

Science Cafes bring together engineers, scientists and townspeople in a relaxed, informal setting, such as coffeehouses and pubs. The speaker makes a short presentation about a topic in his or her field, and then opens up the floor to discussion.
