Moths Threaten Hemlocks in National Park

A 'new' pest destroying hemlock trees concerned park managers in Nova Scotia's Kejimkujik National Park in 2002. It took forest ecologist Blair Pardy a year to identify the invader. It turned out to be a native moth that had not been seen since the 1950s. The pale-winged moth had not been known to seriously defoliate hemlocks before.

Park managers are watching for a return of the pest this year. They are developing a replanting strategy and hoping chemical controls will not be necessary.
