Tropical peatland is a unique ecosystem that is susceptible to fire and drainage. The degraded peatland will take a long time to recover and return to its original condition. The research aimed to identify plant diversity of degraded tropical peatland in Talekung Punai village, Central Kalimantan. Line transects were used along 330 m with size 10 m x 100 m to estimate plant diversities. The results showed high abundance of Galam Melaleucea leucadendra followed by Muhur Lagerstroemia speciosa, Takerung Archiedendron pauciflorum, Halaban Vitex pinnata, Kayu emas Ilex cymosa, Kayu tupi Syzygium polyanthum, Hampuak Baccaurea bracteata, Buton Syzygium sp., and Tabati Syzygium lineatum. A plant diversity index based on Shannon – Wiener was categorized as low with a value of 0.8. KEYWORDS: Degraded peatland, diversity, plant
