  2. CP Rail’s Roger’s Pass Project, 1983 - 1989

  3. Detailed reclamation plans developed for each section of the project. Followed successional patterns identified in the surrounding area. Incorporated the requirements of the rail line in the revegetation design.

  4. The first contract let on the Roger’s Pass Project was for the collection of seeds and propagules from the local area. Over 1,000,000 local native plants were planted, more than half of which were alder. This was the first major native plant purchase in Western Canada and provided a start to several native plant nurseries.

  5. Alder was the main species that was planted…

  6. …but a wide variety of species were used…

  7. …for specific sites.

  8. Native species planting was a major part of the restoration program.

  43. Height vs. Age 2007

  44. Natural sites have an average growth rate of 0.54 m/yr

  45. Trees on the trial site have an average growth rate of 0.69 m/yr

  46. Planting strategy based on trial results, July 31, 2007

  47. By following the successional model of the forests around the site we can make reclamation a profit centre...

  48. ...and the trees just jump out of the ground, even on mine wastes, July 17, 2009…
