摘要: Abstract In this study we evaluate whether infertile wetlands had higher conservation value than fertile based on three criteria commonly used in ecological site evaluations: species richness, number of rare and composition. The data consisted composition n = 401 0·25 m 2 quadrats from a wide range types eastern Canada. Infertile richness many more did wetlands. Further, greater vegetation It is also probable that are sensitive to human disturbances. These results indicate desirable for presently accounted wetland evaluation systems. addition, because variation types, relatively reserves needed adequately represent the
