Other claims from this paper (8)
- Observation Unharvested meadow population growth rate exceeded the outcrop control.
- Observation Outcrop populations were projected to regain initial size within about five years only after 10% rhizome harvesting.
- Observation Projected outcrop recovery took 17 years after 25% harvesting.
- Observation Projected outcrop recovery took 33 years after 75% harvesting.
- Observation Commercially harvested meadow population recovery was projected at six years.
- Mechanism Higher recruitment and faster vegetative growth appeared to explain faster meadow recovery.
- Mechanism Outcrop slow growth and low fecundity delayed recovery after harvesting.
- Recommendation The authors recommend low rhizome harvest rates and rotations of at least five years.
