Fragmented lucidophyllous forests preserved in the precincts of shrines and temples in Tsushima, Nagasaki Pref. and central Miyazaki Pref. were investigated on the relationship between species diversity, species composition and forest area. It was found that the number of lucidophyllous species had a high positive correlation with the log area.Primitive lucidophyllous forests in Mt.Kurinodake, Kagoshima Pref., Mt.Ichibusayama, Kumamoto Pref. and Aya, Miyazaki Pref. were investigated on the species diversity in order to compare species diversity of fragmented lucidophyllous forests.On the rural forests (secondary forests) in Hyogo Pref., for the purpose of increasing species diversity, we managed the vegetation by cutting lucidophyllous shrubs and bamboo grasses and so on, and the vegetation has been investigated after the management. The management of vegetation in this manner is effective for the maintenance and increase of species diversity in rural forests.In the fragmented rural forests, surface soil moisture status was investigated.Semi-natural grassland in Mt.Higashi-otafukuyama was investigated to clarify the actual vegetational conditions and its grassland management. We proposed more suitable management of this grassland, one time cutting per year and removal of cutted plants.Allozyme markers were used to characterize marked special genetic structure in two populations of Blechnum niponicum (Kunze) Makino. Moran's 1 indicated that patch size of Blechnum niponicum was 3-9m, as same as in Pteris multifida Poir. and Dryopteris crassirhizoma Nakai. These reveal that fern population patch size may be smaller then that we usually believe.

对日本对马县、长崎县和宫崎县中部的神社和寺庙周围的破碎光叶林的物种多样性、物种组成与森林面积的关系进行了研究。结果表明，光叶树种的数量与原木面积呈高度正相关。鹿儿岛县栗岳山的原始光叶林，对熊本县市釜山山和宫崎县绫的物种多样性进行了调查，以比较破碎的亮叶林的物种多样性。为了增加物种多样性，我们对植被进行了砍伐光叶灌木和竹草等措施，并对治理后的植被进行了调查。通过对破碎化的农村森林表层土壤水分状况的调查和对东大福山半天然草地的调查，了解了该地区的实际植被状况和草地管理方法。采用等位酶标记技术对两个居群的日本毛蕨进行了遗传结构分析。Moran's 1表明，乌毛蕨的斑块大小为3- 9 m，与多裂凤尾蕨的斑块大小相同。和绵马鳞毛蕨。这表明蕨类植物种群斑块大小可能比我们通常认为的要小。
