Assessment of resistance of hardwood trees against tsunami, targeting coastal forest regeneration following the earthquake, and proposals on coastal forest preparation methods.

Research grant

Project Description

To clarify the resistance of various hardwoods against tsunami, plant hardwoods suitable to the site location, and propose concrete coastal forest creation preparation methods. Specifically, amongst those hardwoods to be grown in the coastal forests of the Pacific Ocean coastline that suffered tsunami damage, comparisons of tree species that were not easily damaged and those with high level resilience will be made with Japanese Black Pines, and selection made. The status of the damage to virgin hardwoods will also be clarifies. Furthermore, planting tests executed to date of hardwoods in coastal forests, and seedling raising techniques for the same shall be re-examined. Based on these results, the feasibility of hardwoods as coastal disaster prevention forests will be studies, and proposals made of which tree species is suitable for which site in each area.

Grant term
2 years and 1 month
September 2011 - September 2013
Grant amount
6,278,000 yen
Activity region
Coastal forests from Iwate Prefecture to Miyagi Prefecture and from Akita Prefecture to Yamagata Prefecture.
It has become clear that the resistance of hardwoods against tsunami significantly varies depending on whether the species tend to wither or are resilient.
