The process of tidal flat biomass formation after the Great East Japan Earthquake: utilizing the inadvertent effects and ecological functions

Research grant

Project Description

This research will investigate ecosystem functions and biodiversity of two new tidal flats created after the Great East Japan Earthquake. Alongside this research, biology monitoring surveys will be carried out by locals on twelve tidal flats scatted across Sendai Bay's Sanriku coast. Holding these workshops for nature observation groups and children means the results will be going straight back into the community. By linking ecosystem research and social education in this way, environmental awareness and re-recognition of the provincial nature is being fostered by local residents to practically conserve Sendai's ecosystem.
