Claim · model-written summary
Agroforestry legacies led to far lower aboveground biomass stocks (42.3 ± 5.4–59.6 ± 7.9 Mg ha−1) than the 106 ± 33 Mg ha−1 expected after 30 years from IPCC standard growth rates.

Other claims from this paper (6)
- Method / resource Satellite-derived aboveground biomass largely overestimated the plot values, at 179 ± 27.3 Mg ha−1.
- Observation Secondary growth rates of 1.41–2.0 Mg ha−1 yr−1 indicate recovery times of about 69 to 97 years to reach average control aboveground biomass (137 ± 12.3 Mg ha−1).
- Observation The recovery time exceeds the average residence time of montane forests at this elevation (71 ± 1.91 years) by 26 years, suggesting non-recovery or far slower recovery to control biomass.
- Observation The abandoned agroforest plot had lower DBH (15.8 ± 5.9 cm) than the control plots (19.8 ± 11.0 cm).
- Observation The abandoned agroforest plot had lower basal area (12.67 ± 0.7 m2 ha−1) than the control plots (28.03 ± 1.5 m2 ha−1).
- Observation The abandoned agroforest plot had a higher abundance of lighter-wood tree genera (0.46 ± 0.10 vs 0.57 ± 0.11 gr cm3) than the control plots.
