The islands were built by Ducks Unlimited Canada to provide upland nesting cover for waterfowl. Twenty islands distributed throughout 12 wetlands (sloughs)were studied. The wetlands are located in east-central Alberta in the aspen parkland ecoregion. The flora and soils of each island were described. Correlation analysis was used to relate total and indiviudal species foliar cover to environmental, primarily soil, variables. A point-intercept frame and a nestingboard were used to record foliar cover in 1-m2 quadrats. Soils (0 - 15 cm depth) were collected within the quadrats. At least 3 quadrats/island were sampled. The quadrats were positioned on the islands using a stratified-random framework. The following soil properties were measured: total N (n), pH, electrical conductivity, exchangeable and soluble cations, sodium adsorption ratio (SAR), exchangeable sodium
