This research examined the diversity and regeneration potential of tree species within Shasha Forest Reserve, Southwest Nigeria, a significant ecological zone with immense biodiversity and socioeconomic value. Tree diversity is a cornerstone of forest ecosystems, influencing nutrient cycling, soil stability, and overall ecosystem resilience. However, factors such as deforestation, habitat fragmentation, and climate change pose substantial threats to the reserve’s ecological balance. This study evaluated tree abundance, species density, and natural regeneration dynamics while identifying anthropogenic pressures, including illegal logging and unsustainable agricultural practices, which exacerbate deforestation and biodiversity loss. Key findings highlighted the role of environmental variables such as climate, and topography in shaping tree diversity patterns and influencing regeneration potential. The study underscored the critical importance of regeneration processes such as seed dispersal, seed banks, and sapling growth in maintaining forest health and promoting biodiversity conservation. Furthermore, it examined the impacts of human induced disturbances on regeneration capacity and identified gaps in current forest management practices. By integrating ecological data with socioeconomic analyses, this research proposed actionable recommendations for sustainable forest management. These included community based conservation approaches, reforestation efforts, and adaptive management strategies to mitigate environmental challenges and enhance forest resilience. This work contributed valuable insights to the ongoing efforts to conserve Nigeria’s forest reserves and underscored the necessity of balancing ecological preservation with human developmental needs.
