Study on swamp forages in South Kalimantan was conducted to evaluate potency of their production and nutritional qualities. As it is recognized that there are about 235,676 ha of swamp are in South Kalimantan poses potential forage, which traditionally used for ruminants. Four indigenous swamp forage plant predominantly grow in the swamp of South Kalimantan. They are Kumpai Batu (Ischaemum polystachyum. J. Presl), Kumpai Minyak (Hymeneche amplexicaulis Haes), Beberasan (Ludwigia hyssopifolia), and Pipisangan (Polygonum barbatum L). Survey method was used to conduct field observations to identify swamp forage, level of production, carrying capacity, and nutrient content of swamp forage within water loged and unlogged season. The results showed that the dominant species has a high production and good quality nutrition in the spring tide is grass Hymeneche amplexicaulis Haes, production amounted to 1032.60 kgDM ha-1 harvest-1 , nutrient content of 10.88% crude protein (CP), crude fiber (CF) 16.37% with carrying capacity of 3.53 Animal Unit/season. Ischaemum polystachyum. J. Presl production was 989.16 kg DM ha-1 harvest-1 , CP content of 14.3%, CF 17.35%, with carrying capacity of 3.39 Animal Unit/season. Ludwigia hyssopifolia production amounted to 851.67 kg DM ha-1 harvest-1 , CP content 15.96%, CF 25.23%, and carrying capacity of 2.91 Animal Unit/season. Polygonum barbatum L production was 889.71 kg DM ha-1 harvest-1 , CP content of 16.45% and 16.27% CF, with carryng capacity of 3.04 Animal Unit/season. It can be concluded that there were four types of species as a potential forages for ruminants feed.
