Other claims from this paper (8)
- Observation Pine stand stability became critical at 10–20 years as foliage biomass peaked.
- Observation Foliage biomass peaked at 7–13 t ha−1 dry weight.
- Observation Natural stands may abruptly lose foliage biomass at canopy closure.
- Observation Natural stand foliage biomass increases again by age 40–50 years.
- Observation Plantations may undergo die-back and collapse before maturity in the critical period.
- Observation Stem biomass increases monotonically independent of stand origin.
- Observation Root biomass increases monotonically independent of stand origin.
- Association Ground water level influences total biomass production.
