| Research Abstract |
In order to investigate the effects of traditional management techniques for the forest decline due to the Great Cormorant, field and laboratory experiments were conducted by using the potted Japanese black pines, which are the dominant species when the guano collecting were conducted in Unoyama colony in Aichi, Japan. The survival and growth rates of the pines were higher with the treatment of sand scattering and no guano collecting than those with control. The research of the present vegetation showed that Machilus thunbergii is significantly abundant in the area where the pines were planted in the late 1960's. These results show that anthropogenic effects such as sand scattering and pine tree planting could facilitate the forest succession of the cormorant colony.
