Short summary
We investigated the wetland system classified as a threatened ecological community and found that organic-rich soil close to surfaces retains significant moisture necessary for ecosystems. At the base of the swamp an identified sand layer allows relatively rapid drainage and lateral groundwater interaction. Evaporation estimated from stable water isotopes from sediments indicated that groundwater contribution to the swamp is significant in dry periods, supporting ecosystems when water is scarce.
