Factors Influencing the Natural Forest Regeneration at Khadimnagar National Park, Bangladesh

Natural regeneration is an indicator of a healthy forest, hence, understanding the influence site factors on natural significant concern for ecologists. This work aimed to assess impact tree at Khadimnagar National Park (KNP). Biotic (tree density, species richness, and basal area), physical (elevation, canopy openness), soil properties (bulk moisture content, pH, organic matter, sand, silt, clay) data were investigated from 71 sample plots examine their effects density richness in KNP. Stepwise multiple linear regression analysis was done predict both richness. The results showed that pH (p<0.001), openness (p<0.01), bulk (p<0.01) had effect explaining 42% total variation. Regeneration driven by four factors: elevation with model explained 60% study observed are main controlling influenced regenerating Therefore, these findings have implications resource management, especially selecting suitable silvicultural systems tropical forest under protected area management where enhanced cover conservation biodiversity needed.
