Effectiveness of ecological units for stratification of bird habitat in Yukon-Charley Rivers National Preserve, Alaska

Authors(s) and Affiliation(s)



Point-count data from the bird inventory were used to test the ability of the ecological units to fine-scale vegetation types. The ecological units were a synthesis of geology, landforms, soils, and vegetation mapped at a scale of 1:250,000; the vegetation types were based on vegetation within 50 m of the sample points. Nonparametric multivariate statistical tests showed that both ecological units and vegetation types provide useful and complementary information about bird habitat selection. Ecological units have several advantages over vegetation types as sample-area strata
