Dinder National Park (DNP) harbors diverse tree species and rich wildlife. This study aimed to analyze the spatial distribution patterns of two key tree species, Hyphaene thebaica and Ziziphus spina-christi, within the park. Using the Morisita’s index method, vegetation sampling was conducted across 60 plots to assess the distribution pattern of both species. Results revealed that Ziziphus spina-christi exhibited a clumped distribution pattern with an index value of 1.4, while Hyphaene thebaica showed a stronger clumped pattern with an index of 3.03. The correlation between the two species was calculated as -0.3, indicating a slight negative association in their spatial occurrence. The study suggests that the clumped distribution of these species is primarily influenced by water availability in the riverine environment. These findings reject the null hypothesis of random distribution and highlight the ecological significance of water sources in shaping tree species distribution within DNP. Understanding these spatial patterns can inform conservation and management strategies for sustaining the park’s biodiversity.
