Dry-forest restoration of a ponderosa pine and Douglas-fir site in the East Kootenay
- Total forage production was doubled at the Douglas-fir site where the canopy was opened up to allow a 32% increase of understory light compared to areas partially-cut to allow 9% more understory light
- Production of all grasses combined was tripled at the ponderosa pine site where the canopy was opened up to allow a 44% increase of understory light compared to areas partially-cut to allow 17% more understory light.
- Pinegrass frequency has increased slightly relative to rough fescue frequency at the ponderosa pine and Douglas-fir sites after 6 years
- It is evident that desirable plant species such as rough fescue have not yet been able to reproduce substantially with
the treatments employed, and under the environmental conditions experienced over the study period. Possible limiting conditions include grazing by cattle, elk and deer, and drought.
