Growth of Pinus thunbergii coastal forest after 2011 Tohoku Tsunami damage in Yoshihama, Iwate.

-Measurement of tree shape using terrestrial LiDAR and changes in stem diameter growth-

Abstract

Measurement of tree shape by using terrestrial LiDAR and stem diameter growth by using increment borer and growth band were analyzed to investigate growth changes of Pinus thunberigii after 2011 off the Pacific coast of Tohoku Earthquake Tsunami damage in Yoshihama coastal forests, Iwate. The stem of each individual was tilted in the same direction mainly due to the influence of wind. Though the flooding in the entire forest stands, there were few trees that flooding level reached to their crown. Impact of Tsunami damage to average-level stem diameter growth seemed to be less. The current stem diameter growth are strongly correlated with diameter at breast height (DBH), therefore it can be used DBH as the indicator of future growth.
