Abstract:

Protected areas (PAs) around the globe are considered a reservoir for biodiversity conservation and an engine for ecosystem function and services. The regeneration potential of tropical forests in (PAs) is crucial to plant diversity survival and conservation, amid climate change in the 21st century. The PAs conservation and management status of Sierra Leone is uncertain. This study assessed the seedlings, saplings, and trees species diversity, abundance, richness and regeneration status of tropical forests in four PAs across Sierra Leone. We sampled 60 quadrats in total with each having a dimension of 20m × 20m. We found only a few new species with good regeneration potential in all the forest PAs were assessed, indicating that the resilience of these forests is quite low in the face of anthropogenic activities especially shifting cultivation and logging. Plant diversity index and soil factors were positively correlated, indicating that a decrease or increase in soil physical and chemical properties could affect speciation. The results show that diameter class distribution mainly falls within the 0-30cm category. Furthermore, abiotic factors (like precipitation and temperature), species richness, ecosystem complexity and over story were predicted to have influenced the regeneration and flora diversity of the PAs forests significantly. The results imply that PAs in Sierra Leone are going through serious exploitation and as such, plant diversity and richness is low and the regeneration ability is poor due to weak conservation strategies and approaches. It recommended that strategic planning and forest enrichment policies be instituted to mitigate future PAs forest exploitation.
Contribution/ Originality
This study is one of the few studies that investigate plant diversity, regeneration and soil properties across PAs in Sierra Leone. The research contributes to the existing literatures in PAs and their ecosystem characteristics. The article concludes that; PAs in Sierra Leone plant diversity and richness and regeneration ability is low.
