Research on methods for the regeneration of reed colonies in the Kitakami River estuary utilizing steel scrap

Research grant

Project Description

In this project, a survey will be conducted on the state of reed growth, the soil environment, and wild birds in reed colonies in the Kitakami River estuary (Ishinomaki City, Miyagi Prefecture) that have rapidly declined since the Great East Japan Earthquake in order to assess the current conditions of the reed colonies as an ecosystem. In addition, the project will conduct experiments indoors on reed growth under various conditions in order to validate observed causes (hypotheses), as well as experimentally verify the effects of ground height adjustments and nutrient provision using steel scrap in order to propose specific construction methods and conditions for the regeneration of reed colonies in the Kitakami River estuary.
