Chris Watson of Lorneville, a rural community in southwest Saint John, recently saw what he believed to be a centuries-old red spruce near Spruce Lake. He drilled a small hole into the trunk by hand and took a pencil-sized sample to have it tested. Ben Phillips, environmental lecturer at Mount Allison University, began a process known as dendochronology on the sample — a study that measures the age of trees by counting small lines otherwise known as tree rings. “This tree, I can confidently say, is over 400 years old,” Phillips, who runs the Acadian Forest Dendochronology Lab on campus, said about the sample he got from Watson. “It is probably in the top 10 oldest trees in the province that I know of.” …Both Phillips and Ilana Urquhart, Nature Trust of New Brunswick conservation co-ordinator, want to see legislation put in place in New Brunswick that would protect areas with old growth, specifically.
