Peat swamp forest has high conservation value and various functions, including hydrological function, carbon stock, and also flora and fauna habitat. However, in the last few decades there has been damage to peat swamp forests, therefore forest restoration efforts are needed. The first step in designing forest restoration is studying the condition of the existing ecosystem. The Katingan Peat Swamp Forest is one of the peat swamp forests in Central Kalimantan which is experiencing degradation and needs restoration. Based on the existing vegetation conditions, particularly in terms of composition, structure, and regeneration potential, it is necessary to consider the appropriate forest restoration techniques for the Katingan Peat Swamp Forest. The aim of this research is to describe the species composition, stand structure, and regeneration potential of tree communities in the Katingan Peat Swamp Forest. This research uses secondary data on the Katingan Peat Swamp Forest vegetation in 2015 published by the Center for International Forestry Research (CIFOR). The CIFOR research team collected vegetation data in July and October 2015 in two different locations, namely the north side and the south side of the area. Vegetation data were sampled from two main plots at each location with an area of 100 m x 100 m and divided into 25 sub-plots measuring 20 m x 20 m. The parameters measured were the diameter (DBH) of individual trees with a minimum size of 2.9 cm and local names. The data analysis carried out in this study was based on a combination of data from the two plots. Types of analysis carried out were floristic composition, stand structure based on diameter class, tree regeneration potential based on the presence of saplings at sapling level and tree type based on succession status using wood density based classification. The analysis showed that in the research area there were 2,719 individual trees from 59 species and 24 families. Vegetation is dominated by Mangifera parvifolia and generally the vegetation is composed of species that have high commercial value and are able to adapt to degraded land conditions. The total area of base area (LDBS) is 24.42 m2 / ha and stands are dominated by small diameter trees. The number of individuals at the sapling level is higher than poles and trees, indicating that the Katingan Peat Swamp Forest has good regeneration potential. There are 24 species out of 30 tree species or 80% have good regeneration potential. Based on its succession status, 60% of the vegetation is dominated by pioneer species.
