Other claims from this paper (9)
- Observation The Cercidiphyllum japonicum population inhabits sandy, organic-rich, weakly acidic yellow-brown soils.
- Observation The age structure of the population approximates an irregular, spindle-shaped pyramid.
- Observation The population relies on sprouting for regeneration.
- Observation Population dynamic indices indicate a marginally growing but stable population.
- Observation The survival curve of the population conforms to the Deevey-III type.
- Observation High mortality occurs in early life stages of the population.
- Observation Time-series forecasting suggests that the current abundance of middle-aged individuals could maintain the population in the short term.
- Mechanism Recruitment failure, intense environmental filtering and historical logging are the primary drivers of the endangered status of Cercidiphyllum japonicum.
- Recommendation Conservation of this population should prioritize artificial regeneration to supplement seedlings, active management of existing sprouts and long-term monitoring.
