Recovery strategies for industrial development in native prairie in the Dry Mixedgrass natural subregion of Alberta

Publication Date:

Alberta’s Grassland Natural Region has been significantly modified by land use practices. ┬áThe semi-arid climate of the Dry Mixedgrass Natural Subregion (DMG) supports native plant communities adapted to drought. Minimizing soil disturbance and natural recovery are often the most effective strategies for restoring DMG native plant communities. This document identifies strategies designed to retain and restore native grassland plant communities following disturbance in the DMG. This manual describes tools for planning native grassland retention and restoration, including pre-disturbance planning and recovery strategies, such as minimal disturbance, buffers, natural recovery and native seed mix design. Implementing a strategy is explained, including site preparation, soil amendments and procuring native seed, then maintaining the pathway using invasive plant and grazing management, and long-term monitoring. Appendices include a summary of regional reclamation studies and suitable seed mixes to develop target plant communities for ecological range sites common in the DMG.
