Community structure and regeneration pattern of Abies spectabilis in Sagarmatha National Park, Central Himalaya, Nepal

A study of Abies spectabilis in Sagarmatha National Park, Nepal, revealed a discontinuous regeneration pattern, deviating from the typical reverse J-shaped curve. This suggests limited seedling development into saplings, potentially due to moderate disturbance from livestock grazing or environmental factors. The research analyzed community structure and population characteristics along an elevation gradient (2750–3550 m asl), finding A. spectabilis as a co-dominant species with high diversity. Tree density varied significantly with elevation, peaking at 3450 m but declining at higher altitudes. These findings highlight the vulnerability of this species to unsustainable use and environmental pressures.
