Researchers have discovered six trees in Algonquin Provincial Park that are more than 400 years old — located in a logging zone they are now urging the government to protect from logging, the Star has learned. …The “very old, unprotected forest is about 1.7 square kilometres in size, roughly equivalent to Toronto’s Sunnybrook, Wilket Creek, Glendon and Serena Gundy Parks combined,” said Mike Henry, a senior ecologist and lead researcher of the Algonquin Park Old-Growth Forest Project. …“There are a number of large, roadless areas in Algonquin Park that are unprotected; some are at imminent risk of being logged,” he said, saying the current rules “are no longer viable.” Algonquin was Ontario’s first provincial park and is the oldest in the country, created in 1893. Logging has always been allowed, though it is the only such park in the province — and one of two in the country — where that is the case.
