The CP Rail Roger`s Pass Project created a new rail line through the heart of Glacier National Park.  Restoration was a major part of the impact mitigation plan developed for the project.  Restoration work entailed the establishment of a suitable growth media (soil), a cover of seeded grasses and legumes to control erosion and the planting of woody species.  Sitka alder was used as an initial woody species cover with later successional conifers planted underneath.  These are now starting to overtop the alder and form the dominant cover.
