We are involved in surveys and technology research into protecting the natural environment, to help build a foundation for richer life for future generations. One of our key research themes is the biotope. We are involved in every phase of biotope activity, from planning and proposal to organism acquisition, analysis, design and construction. Pollution-free air, water and soil. Safe homes. Sufficient food. For living organisms - including human beings - these are essential things. Preserving an environment where all organisms can live as they are supposed to, in other words preserving sound ecological systems, is a key part of today's environment problems. By creating biotopes, which provide the organisms scattered throughout our local region with a place where they can thrive over the long term, we are promoting sustained development of both the natural environment and human beings and working toward a mutually prosperous future. The advance survey of the target region is a key step in the creation of biotopes, namely the restoration of regional ecological systems. By identifying and analyzing the environmental factors (not only organisms, but also chemical and physical factors) present in the region it is possible to determine what is necessary and what is not. Tsuchiya-gumi takes these analysis results and the ideal form of the natural environment, and uses them as the basis to develop a biotope construction plan, covering every step from organism and other surveys to analysis, design and construction. Our goal is to preserve and restore the ecological system. We also provide youth with expanded opportunities to come into contact with nature through a range of grant and subsidy programs, as well as providing environmental education to help others understand the importance of environmental preservation. Advance surveys - Organisms - Chemical factors - Physical factors   Analysis   Planning and design   Construction   Maintenance Environmental education A biotope is a place where the organisms of a region can live and thrive over the long term. Originally created in Germany, the word is a combination of the Greek words bios, for biology, and topos, meaning place.
