Establishment of pasture for environmental education, which aimed to coexistence of agriculture and wildlife in reclaimed land.

为了在《拉姆萨尔条约》中登记为湿地的复垦地建立环境教育农场，必须制定湿地生态草地开垦方法、现有生物群落管理手册、生物群落建立方法、环境教育农场管理等。我们的目标是解决这些问题。为了保护填海土地，特别是在围垦地周围的水田被淹没时，需要抽排水。为提高排水效果，2002年和2003年分别对侧排水沟、农田排水沟和鼹鼠排水沟进行了整治。其结果是地下水位下降，农田排水沟的排放量增加。特别地，鼹鼠排水有助于排水效果，保持土壤干燥。它抑制芦苇的生长，促进牧草的生长。根垫被圆盘耙压碎了。它有助于增加种子的数量，播种在破碎的根垫之间的裂缝。种子在裂缝中的发芽率高于在根垫上的发芽率，与在根垫上发芽相比，裂缝中的根系生长得到改善。无耕林初期的重度放牧抑制了芦苇的再生，改善了牧草的生长。我们确认了一种濒临灭绝的物种，巨蜥使用了已建立的牧场。林下生长对黑麦分布的影响。我们还证实了稀有物种的存在，并获得了关于芦苇燃烧效应的新知识，尽管有些主题仍然存在。开展了环境教育农场导游员培训班。我们还举办了论坛和工作坊，向市民宣传我们的知识。这些活动为管理和明智使用奠定了基础，并将有助于未来的使用。

In order to establish the environmental education farm in Hotokenuma reclaimed land, where was registered as the wetland of Ramsar treaty, it is necessary to establish the ecological grassland reclamation method in wetland, management manual for present biotope, method for establishing biotope, and managing of the environmental education farm. We aimed to resolve these subjects.Pumping drainage is necessary to keep reclaimed land, especially during inundation in paddy field surrounding Hotokenuma reclaimed land. Lateral drainage canal, farm drain, and mole drain had been settled in 2002 and 2003 for improvement of drainage effect. As a result, underground water level lowered and discharge by farm drain increased. In particular, mole drain contributed to drainage effect and soils were kept to be dry. It made depressed growth of common reed (Phragmites australis) and enhanced growth of forage grasses.Root-mats were crushed by disc harrow. It contributed to increase in number of seed which were sown in the cracks between crushed root-mat. Germination percentage of seed in the cracks was higher than that on the root-mat and root growth in the cracks was improved compared germinated on the root-mat. Heavy grazing at the initial stage of non-tilled establishment depressed regrowth of common reed and improved establish of forage grasses. We confirmed that an endangered species, Megalurus pryeri used established pasture. Growth of understory affected on the distribution of Megalurus pryeri. We also confirmed inhabiting of rare species and acquire new knowledge concerning effects of burning on common reed, although some subjects were remained.Training course of escorting guide for environmental educational farm was carried out. We also held forum and workshop as the publicity activities for extending our knowledge to citizens. These activities made the base for management and wise use and will contribute to future usage.
