摘要: We undertook a gap analysis of how protected areas represent the tree-species diversity within Canadian boreal forest, as measured from Forest Resource Inventory (FRI) maps. used new compilation designed to support ecological analyses over large and across jurisdictional boundaries. The was stratified into four analytical regions determined by terrestrial ecozones. calculated relative abundance species regions, developed rarity criteria, evaluated abundances prevalence rare species. characterized representation gaps when tree in an region differed markedly (by more than factor 2) expectation, product regional proportional area protected. Most were well represented most species-diverse (n = 33), Boreal Shield eastern Canada, due apparently number relatively...
