The Nova Scotia government is taking steps to preserve old-growth forests in the province, although at least one sustainability advocate would like to see the effort come with more teeth. Natural Resources and Renewables Minister Tory Rushton announced Thursday that an updated version of the province’s old-growth forest policy is effective immediately. Rather than adding legal protection to all old-growth forest on Crown land that isn’t already part of a protected area, the government is extending “policy protection” to those lands in question. …Policy protection means stands of old-growth trees will eventually become part of conservation areas in the so-called triad model that determines where and what type of forestry activity can take place on Crown land. …the triad model breaks Crown land into three areas: one for conservation with no forestry activity; one designated for light-touch ecological forestry; and one designated for high-intensity forestry.
