Degradation of net ecosystem carbon balance in cool-temperate forests by sika deer-induced stand structure alterations and subsequent soil erosion

Hayato Abe, Dongchuan Fu, Tomonori Kume, Ayumi Katayama

This study shows that sika deer overbrowsing and soil erosion reduce net ecosystem carbon balance in forests by altering stand structure and increasing carbon loss.
