This research was carried out from 2007 to 2009. Methods The termites were collected from their mounds and surrounding areas and identified. Twenty villagers were interviewed on their use of termites and their mounds in the village. Sixty-three mounds were measured to determine their dimensions in early March early July and middle to late November 2009. Results Eleven species of Termitidae were recorded during the survey period.

To ensure sustainable termite utilization in the future studies should be conducted to enhance factors that promote mound restoration by termites. Furthermore it will be necessary to improve mound conservation methods used by the villagers after changes in the soil mass of mounds in paddy fields and forests has .
