We have been resarching the origin, decrease and recovery of the "Hirotani Moor"in Hiraodai Karst since 1994.
In origin, why does the moor exist on the Karst without water? We made a proof from "crescent lake"-point of view by the flow observation and river measurement.
In Decrease, we compared our measurement result of studying for seventeen years (in 1994,2001 and 2010), and considered the reason of decrease. We find out that the moor had decreased more than 60% by human. We measured the moor this March. During the measurement, We found many new discoveries and research about the decrease or regeneration of the moor.
In Recovery,We think that to return the time line of the moor is the human duty. So, we start the preservation activity. For one of them, we are doing the Ramsar Convention registration activity.
