This study was performed to evaluate the Ip-am wetland located in the Naejang National Park by
analyzing vegetation and landscape and to suggest management plans. We carried out field survey in 2013 and
analyzed aerial photos in 1976 and 2010 for landscape change. As a result, the places that were paddy fields in
the past were dominated by 5 communities such as Salix koreensis Community (21.6%), Persicaria thunbergii
Community (2.8%), Phragmites communis Community (1.1%), Molinia japonica Community (4.9%), Persicaria
thunbergii-Molinia japonica Community (0.5%). On the other hand, the places that were upper fields in the
past were occupied mostly by Rosa multiflora Community (6.8%), Humulus japonicus-Rosa multiflora
Community (42.0%), Humulus japonicus Community (10.6%). In order to maintain and manage the wetland,
water should be supplied continuously by making use of the six among the seven reservoirs located in the
upper part through the hydrological survey should be accomplished. In addition, it was necessary to reinforce
the banks for minimizing water outflow. It contributes to prevent dry peat and decrease in decomposition
speed. Thus, it is hard to invade and settle of terrestrial plants and then secondary succession would be delayed.
