Erosion resistance of substrate 2 years after installation of sprayed vegetation substrate

Year Published:2009
Author:Daisuke Hosogi・Ryo Saeki・Masahiko Matsue

The erosion of the vegetation substrate was continuously investigated over a period of two years in the field in three experimental areas: (1) an area sprayed with only the vegetation substrate, (2) an area where the vegetation substrate was mixed with topsoil, and (3) an area where the vegetation substrate was sprayed with normal vegetation substrate including seeds for greening.

Formula for Calculating CO2 Fixation of Urban Trees in Japan

Year Published:2009
Author:Masahiko Matsue・Yousuke Nagahama・Yasuo Izuka・村田みゆき・Fujiwara Nobuo

We developed formulas for calculating annual dry weight growth of woody parts and annual CO2 fixation based on these formulas for tree species commonly used for urban greening in Japan, with an application range up to about 50 years of age. The target tree species are camphor tree, Japanese white oak, Japanese maples, zelkova, ginkgo, and plane trees.

Revision of Guidelines for Road Earthworks and Biodiversity

Year Published:2010
Author:Masahiko Matsue

The revision of the “Guidelines for Road Earthworks” was started in 2004, and the “Guidelines for Cut-and-Fill and Slope Stabilization” was published on June 30, 2009. In addition to the revised contents, some of the ideas on preservation and conservation of the natural environment, etc., as indicated in the basic policies of the guidelines, are introduced in this report.

Potential use of forest topsoil stored for one year as a greening material

Year Published:2010
Author:Daisuke Hosogi・Masahiko Matsue

In order to investigate efficient methods of preserving forest topsoil that can be collected during land development for use as revegetation material, we conducted an experiment in which forest topsoil was preserved as fill in the field and air-dried or sealed and moistened indoors for a period of one year.
