| Research Abstract |
As a novel technique for natural forest management in snowy regions, we aimed at developing snow control treatments that contribute to prevent snow blight diseases at the seed germination stage and to facilitate natural tree regeneration. Results from our field trials indicated that the artificial formation of uneven ground surface may be an effective treatment particularly on a lower elevation. It enhances soil frost during winter, which likely has a positive effect inhibiting seed infection and damage caused by the pathogenic fungus and increasing the rate of germination in a natural forest.
