Abstract

Botanical Forest Park (Tahura) is very important to support human life and the environment. The purpose of the study was to analyze the structure of the vegetation community, including the level of diversity, and the similarity of the vegetation community. The research method follows the sampling technique procedure with the plot method. Data were analyzed using the Index of Important Value to test the mastery of the species, the Shannon-Wiener Index to test the level of diversity of vegetation species, and community stability, community similarity index to test the similarity between flora communities. The results obtained are the value of the species diversity index, in general, is included in the medium category, which means that productivity is sufficient, ecosystem conditions are quite balanced, and ecological pressure is moderate. The species evenness index is high, the species richness index is in the medium category, and the similarity index between plant communities is very high.

Abstract

Medicinal plants are one of the essential ecosystem services provided by Indonesia's tropical forests. However, threats such as deforestation, forest degradation, climate change, and overharvesting jeopardize the existence of medicinal plants. This study aims to examine the diversity of medicinal plant species in three village forests in Central Kalimantan. The identification of medicinal plant species, including their local names, growth forms, and the number of individuals, was conducted using observation plots. Analysis was performed by calculating the Species Diversity Index, Species Richness Index, and Species Evenness Index. This research identified 69 species and 650 medicinal plant individuals. The study found that the diversity, species richness, and evenness of medicinal plant types varied across locations. Two villages exhibited medium diversity and richness index values (H’= 2.47 – 2.87; R= 3.82 – 4.48), while only one village was classified as having high values (H’=3.07; R=6.81). The species evenness index in all three locations showed a high category (E=6.69 – 11.54). The medicinal plants utilized by the community were predominantly climbers, herbs, and trees. High diversity of medicinal plant species was found in forest areas protected by customary regulations. This research conclude that di diversity of medicinal plant categorized as medium-high, and there are sign of declining biodiversity. Therefore, conservation program is urgently needed and encourage relevant stakeholders to participate.
