Abstract Kanchanasaka B. 2009. Situation of the Hairy nosed otter in Pru Toa Daeng Peat Swamp Forest. Wildlife Yearbook 9, 1-28 .

Pru Toa Daeng peat swamp forest is the biggest remain peat swamp forest in Thailand. It was declared as Ramsar site in 2001. Not only its unique ecosystem and the high biodiversity of flora and fauna, it was the important habitat of some endemic species of birds and mammals. The hairy nosed otter was endemic in South East Asia and also critically endangered species. It has been rediscovered in Thailand again after its status was not reported for more than 20 years. However, their population in Toa Daeng peat swamp forest was the biggest viable population in Thailand and distributed inside and outside the protected area. The population inside the protected area were in Chalaem Pra Kiet Wildlife Sanctuary but the population outside the protected areas were in the reserved forest, Nikon Sahakorn Pilenght and also the private properties. The population of the hairy nosed otter outside protected area was small and scattered in many forest patches. Those fragmented forest were surrounded by villages, plantation, rice field and orchards. The population were connected by Khlong Nam Bang and Bang Nara River. Population in the protected area inhabited in the melaluca forest and evergreen forest. Their distribution and habitat utilization depend on season and food. In wet season, otters were scattered but in dry season otters were dense along Suhai Padee canal, swamps and ponds in melaluca forest and also in Khlong Toa Daeng in the evergreen forest. In wet season, fish population were scattered to find the spawning place and it was difficult for otters to catch fish. In this period, the frequency of fish traps disturbed by otters were high. Opposite to the dry season when water level was decreased and fish population accumulated in ponds and canals, otters could catch fish easily. Therefore, fishing trap disturbances by otters were very low. Those behavior were related to

the study of their diet. Fecal analysis found 80% of fish, 13.3% of crab and 3.5% frog in the scat samples. Identification of fish scales found the snake head fish, three spot gourami, common climbing perch and grey feather back. Amidst the social conflict in three province of southern border affect to our research and the hairy nosed otterså habitation. The outer rim of Toa Daeng Peat Swamp forest were encroached by plantation. Therefore, evergreen forest at the centre of peat swamp forest would be the important site for the hairy nosed otter conservation.
