Question: Can a wet meadow plant community be established on abandoned peatlands through broadcast plant diaspore spreading in western Canada? Does fertilization impact the development and establishment of the wet meadow?
Location: Evansburg, Alberta, Canada
Methods: Wet meadow vascular and non-vascular species were spread under 2 treatments on an abandoned peatland. The effect of spreading and fertilization treatments were tested using a factorial randomized unbalanced design repeated six times. Treatments were used to statistically test main effects and interactions. A barley (Hordeum vulgare) straw mulch cover was applied on all experimental units.
Results: Plant spreading was an effective restoration method for establishing vascular wet meadow vegetation on sites with sufficient moisture. The treatments that included plant spreading had 80% coverage by wetland dependent vegetation and a distinct decline in agronomic and upland species. Fertilization had no significant effect on plant cover.
Conclusion: The use of a modified Sphagnum moss layer transfer method to establish a wet meadow plant community on a post-abandoned peatland was successful and contributes to the development of a new approach towards managing abandoned peatlands in mid-continental boreal Alberta, Canada.
