How do ground litter and canopy regulate surface runoff?—a paired-plot investigation after 80 years of broadleaf forest regeneration

Relatively minimal attention has been given to the hydrology of natural broadleaf forests compared to conifer plantations in Japan. We investigated the impacts of ground litter removal and forest clearing on surface runoff using the paired runoff plot approach. Plot A (7.4 m2) was maintained as a co...
