Does pre‐existing vegetation make a difference for re‐establishing native shrubs ?
There exists within the Canadian prairies large areas seeded to monocultures of introduced grass species.Introduced species cover large areas of land in North America.Smooth brome grass ( Bromus inermis ) is one of the more plentiful.Chosen for agronomic reasons but is also known for its invasive potential for surrounding native grassland.This grass as a monoculture is susceptible to many of the shortcomings found with monocultures such as increased sensitivity to environmental events, low diversity in structure and species (fauna and flora), and lower long term productivity.There exists a need to increase diversity by replacing and/or re‐establishing native species to increase biodiversity both from an ecological perspective as well as sustainability perspective.This work has set out to determine the differences which occur between alluvial soils beneath stands dominated by smooth brome, native grass ( dominated by A gropyron ssp.) and buffalo berry ( Sheperdia argentea) for establishment of two native shrubs ; silver sage ( A rtemisia cana) and buffalo berry.
