Krawak forest is a protected forest that function to regulate water management, prevent fliooding and erosion, and maintain soil fertility. One of the plant habitus that contributes to the vegetation in the Krawak Forest is herbs. The existance of herbaceous plants in Krawak Forest is quite diverse, but so far there is no information about the species composition and diversity. This study aims to analyze the vegetation of herbaceous plants in the Krawak Forest by calculating species density, important value index, and diversity. The research was carried out on April 26, 2022.The type of research is quantitative descriptive, the sampling method is the quadratic method with a size of 1mx1m with 4 plots. Data collection techniques were carried out by recording the name and number of each species found in the plot, as well as the area covered by each species. Data analysis was carried out by calculating species density, dominance, and frequencys as the basis for calculating the important value index of each species. In addition, the Shannon-Wiener diversity index was also calculated to determine the level of diversity of herbaceous plants in the forest. The results of the study found 13 species of herbaceous plants belonging to 8 families, each family having a number of varied species as well as the number of individuals in each species.The highest species density was owned by Typhonium flagelliforme with a value of 38.36 and the lowest was Digitaria sanguinalis, Commelina benghalensis, and Verbesina alternifolia with the same value of 1.37. The highest important value index was Chromolaena odorata with a value of 54.60 and the lowest was Digitaria sanguinalis and Verbesina alternifolia with a value of 6.91. The diversity index obtained a value of 2.14 where this value indicates the level of forest diversity in Krawak forest is in the medium category.

“…However,the publications are generally related to resin production (Hadiyane et al 2015;Wijayanto et al 2019;Indrajaya 2020;Sukarno et al 2020;Mukhlisa and Dwiyanti 2021;Alam et al 2023;Samis et al 2023). Meanwhile, several publications related to tree diversity are by Siswo et al (2019), Natalia et al (2020), andItawamerni et al (2021). Furthermore, Supartono et al (2022) conducted research in the P. merkusii forest in the TNGC; this research was only carried out in one place far from natural forest.…”

Abstract. Supartono T, Adhya I, Kosasih D, Wildani W. 2023. Tree species diversity adapted to Pinus merkusii forests in Gunung Ciremai National Park, West Java, Indonesia. Biodiversitas 24: 4314-4323. One of the challenges faced in rehabilitating pine forests in conservation areas is the limited information on plant species capable of adapting to these ecosystems. This study aimed to analyze the diversity of tree species that grow and adapt to pine forests and the relationship of natural forests with the vegetation characteristics of pine forests. The research was conducted in pine forests bordering natural forests and far from natural forests using the sample plot method. The study recorded 44 species from 27 families of seedlings, 46 species from 21 families of saplings, 25 species from 18 families of poles, and 24 species from 17 families of trees. Accumulation of species from all growth stages recorded 83 species (76 local species and 7 cultivated species) from 39 families. Based on the species accumulation curve, pine forests adjacent to natural forests have more species than those far from natural forests. Individual and family density in pine forests adjacent to natural forests were also higher than the density of these two variables in pine forests far from natural forests. Furthermore, both the pine forest adjacent to the natural forest and that far from the natural forest, each has its own species peculiarities. The results indicate that the existence of natural forests has an important role as a source of biodiversity for the surrounding ecosystem. As an implication of this study, species that can grow to the level of poles and trees can be recommended as rehabilitation plants in the Pinus merkusii Jungh. & de Vriese forests in Gunung Ciremai National Park, Indonesia because pine is not a local species and the allelopathy it releases can reduce plant diversity.
