Other claims from this paper (12)
- Intervention effect Harvest treatments strongly affected height and volume growth, with a smaller effect on diameter.
- Intervention effect Mechanized harvesting reduced mean annual increment by 33% versus chainsaw harvesting.
- Intervention effect Stump height did not influence growth after chainsaw clear cutting.
- Intervention effect Low stumps after Feller Buncher harvesting reduced growth by 23% versus high stumps.
- Intervention effect Stump cleaning did not produce a yield difference.
- Intervention effect Chainsaw harvesting had leaf area index 3.3 versus 2.1 after Feller Buncher harvesting.
- Intervention effect Chainsaw harvesting had light use efficiency 0.7 versus 0.57 g MJ−1 after Feller Buncher harvesting.
- Observation Intact stumps, stand uniformity, light capture and light use efficiency had reported r-squared values of 67%, 55%, 60% and 86%, respectively.
- Intervention effect At operational scale, Feller Buncher harvesting had lower MAI than chainsaw harvesting, 37 versus 44 m³ ha−1 y−1.
- Intervention effect Feller Buncher harvesting lowered survival to 88% versus 96% after chainsaw harvesting.
- Intervention effect Feller Buncher harvesting lowered stand uniformity.
- Recommendation Coppice systems should account for harvest operation costs and efficiencies because they affect subsequent survival and production.
