Revegetation trials were established in 1977 on a disturbed montane grassland in Jasper National Park, Alberta . The trials were designed to test the effectiveness of topdressing, fertilizer and seeding method treatments to establish native vegetation cover .
Ground cover and yield responded negatively to topdressing with either peat or with loamy sand similar to the native soil. Positive results were achieved by fertilizing at the time of seeding. These improvements have persisted, indicating that the nutrients are being cycled. Method of seeding did not significantly affect ground cover.
The results indicate that, if weather conditions are suitable, seedbed tillage and broadcast seeding alone can be sufficient to establish a productive native community in a montane environment.
