Due to rising global warming and climate change, biodiversity protection has become a critical ecological concern. The rich biodiversity zones are under threat and are deteriorating, necessitating national, regional, and provincial efforts to safeguard these natural areas. The effective conservation of National Parks and Nature-protected Areas helps to improve biodiversity conservations, forest, and urban air quality. The continuous encroachment and abuse of these protected areas have degraded the ecosystem over time. While exploring the geophysical ecology and biodiversity conservation of these areas in West Africa, Kainji National Park was selected for this study because of its notable location, naturalness, rich habitat diversity, topographic uniqueness, and landmass. The conservation of national parks and nature-protected areas is a cornerstone of biodiversity conservation globally. This study is aimed at the target of United Nations Sustainable Development Goal 13, 2030- Climate Action, targeted at taking urgent action towards combating climate change and its impacts. The study captures both flora and fauna that are dominant in the study area. The 15 identified trees were randomly sampled within a stratum of 10x10km shared into 24 plots for proper analyses using i-Tree Eco v6.0.23 software. The following data were captured and analyzed; Photosynthetically Active Radiation, Rain/Precipitation, Temperature, Transpiration, Evaporation, Water Intercepted by trees, Avoided Runoff by trees, Potential Evaporation by trees, Isoprene and Monoterpene by trees. This study also further discusses the tree benefits of green, low carbon, and sustainable environment within the context of biodiversity conservation considering carbon storage, carbon sequestration, hydrology effects, pollution removal, oxygen production, and volatile organic compounds (VOCs). There is a quick need for remotely-sensed information of the protected areas at regular intervals and government policies must be strict against illegal poaching and logging activities.
