Effects of alteration of management to forest floor vegetation and environment of secondary coppice forests in urban areas, Tokyo: II. Relation between the forest management methods and light, temperature or the soil conditions

An appropriate management of the secondary coppice forests is necessary to maintain various effect functions. In this research, it was investigated that what of environment is influence to the managed forest floor and the abandoned these. In the forest subjected rough removal of litter and undergrowth in winter, the amount of penetration of light to the forest floor was high. The air temperature in these managed and abandoned forest in a fine day was the same value in daytime. However, for nighttime, the values of air temperature in the abandoned forest for a long term were lower than the managed and the abandoned forest in a short term, and the values of soil temperature were lower than those a day. In the soil of the managed forest floor, hardness and the amount of moisture were higher and porosity was lower than of the abandoned ones. These values of the abandoned forest floor for a long term become a tendency seriously.
