The Najeoer Pond was created in a rice paddy as a part of a plan to build the National Institute of Ecology. To induce the establishment of various plants, the maximum depth of the pond was 2.0 m, and diverse depths were created with a gentle slope on the pond bed. When introducing vegetation, littoral and emergent vegetation were first introduced to stabilize the space secured for the creation of the pond, whereas the introduction of other vegetation was allowed to develop naturally. In this pond, floating, emergent, wetland, and littoral plants have been established to various degrees, reflecting the water depth and water table. As a result of stand ordination, based on vegetation data obtained from the created Najeoer Pond and a natural lagoon selected as the reference site, the species' composition resembled that of the reference site. Diversity, based on vegetation type, community, and species, tended to be higher than that of the reference site. The proportion of exotic species increased due to the disturbance that occurred during the pond creation process but continued to decrease as the vegetation introduced during the creation of the pond became established. Considering these results comprehensively, the restorative treatment served to increase both the biological integrity and ecological stability of the pond and, thus, achieved the creation goal from the viewpoint of the pond structure.
纳杰奥尔池塘是在一片稻田中建造的，作为建设国立生态研究所计划的一部分。为了诱导各种植物的生长，池塘的最大深度为2.0米，并在池底设置了不同深度且坡度平缓的区域。在引入植被时，首先引入了沿岸植被和挺水植被，以稳定为建造池塘而预留的空间，而其他植被则任其自然生长。在这个池塘中，浮叶植物、挺水植物、湿地植物和沿岸植物都已不同程度地生长起来，这反映了水深和地下水位的情况。根据从新建的纳杰奥尔池塘以及选为参考地点的天然泻湖获取的植被数据进行的群落排序结果显示，该池塘物种组成与参考地点相似。基于植被类型、群落和物种的多样性往往高于参考地点。由于池塘建造过程中发生的干扰，外来物种的比例有所增加，但随着建造池塘时引入的植被逐渐生长，外来物种比例持续下降。综合考虑这些结果，恢复性处理提高了池塘的生物完整性和生态稳定性，因此从池塘结构的角度实现了建造目标。
