Abstract

An indicator of the stability of a community within an ecosystem is diversity of species. The absence of data regarding the species diversity in the campus forest of UIN Sulthan Thaha Saifuddin Jambi prompted the conduct of this study, which aimed to identify tree types and calculate the diversity index and evenness index for the campus forest. To achieve this aim, the research site was selected through the implementation of purposive sampling, whereas the plot was determined through the utilization of systematic sampling. Aside from that, tree data was collected in 22 plots using a quadratic method with dimensions of 20 m x 20 m. The research findings revealed the acquisition of 83 tree species, comprising 30 families and a total of 464/8.62 ha individuals. The species of tree that contains the greatest number of individuals is Ixonanthes sp. The genus Ixonanthes exhibited the greatest INP, which measured 37.64%. At 3.70, the species diversity index (H') indicates a significant degree of diversity across categories. Furthermore, the evenness index (E) acquired a value of 0.84, placing it within the category of high evenness

Abstract

Seedlings are the first stands that grow to replace damaged forest vegetation. Seedlings can have a positive impact on the balance of the wider ecosystem, because seedlings are the beginning of an ecosystem regeneration process that is greatly influenced by that ecosystem The purpose of this research to information regarding the structure and composition of seedling in the UIN Sulthan Thaha Saifuddin Jambi Campus Forest. This research was carried out in July 2022 – March 2023. The research location was determined using the Purposive Sampling Method, determining the plot using systematic sampling, and data collection using the quadratic method with a size of 2 m x 2 m. The observation results were analyzed using the Importance Value Index, Shannon-Winner Diversity Index, Morisita Index, and the Evenness Index. The research results found that there were 332 individuals, 84 types of seedlings, belonging to 28 families. The highest Importance Value Index (INP) is Gmelina arborea Roxb (11.19%), the Diversity Index (H') is in the high category (H' 3.94). The evenness index (E) (0.89) is in the high (even) category.
