| 英文摘要 | Anthropogenic disturbances influence plant regeneration and species diversity; which impact the conservation status of protected areas. A study was conducted in the Sitakund Botanical Garden and Eco-park (SBGE); Chittagong; Bangladesh to analyze the natural regeneration and tree species diversity in disturbed and less disturbed zones. Stratified and systematic random sampling was used to select 50 sample plots from each of the two zones. A total number of 109 plant species from 43 families were recorded in the study; of which 93 species were of natural origin while the rest were planted. From the species with natural origin 66 were tree species; 9 were shrub species and 18 were climbers. Species richness; density of regeneration and disturbance index in the height classes (0 - 0.5 m) and (dbh > 6 cm) indicated significant differences between the zones. The study analyzed how disturbances affect species diversity in the area. It was found that species richness and basal area are negatively related with disturbances. Moreover; density (N/ha) of trees was more likely to decrease with increasing tree height that reflects the huge demand of local people to harvest large trees as part of their income generating activities. The study findings have implications for future management decisions of the SGBE. To restore these ecosystems; management should focus on both biodiversity conservation and providing benefits to local people without hampering forest ecosystems. |
