Abstract

A survey was conducted in 2003 to identify Canadian native tree species (woody perennials 10 m tall) that may be in need of genetic conservation. Thirty expert respondents from various agencies in provinces and territories graded the tree species in their respective geographical regions based on nine criteria that describe potential reasons for conservation (e.g., rarity, decreasing range or frequency, preferred habitat in high demand, uncertain viable seed source) and then provided a rating that identifies the type of conservation that may be required (species is in good shape, insufficient knowledge for a designation, in situ or ex situ conservation measures are required). Either in situ or ex situ conservation was recommended for 52% of Canada's native tree species, and 8% required more information before a rating could be made. The results of the survey will be used to identify genetic conservation priorities for tree species in Canada.
