Research Abstract |
This report shows a sustainable natural forest management system of The Tokyo University Forest. This University Forest is situated in the central part of Hokkaido Island and the area covers about 22,800 ha. The University Forest is a good example of an enterprise scale natural forest management based on selection cutting and natural regeneration. The University Forest has severely damaged by typhoon in 1981, the wind fall volume was 810,000 m^3, which is 18% of total stand volume at that time. This report describes under items. 1) Height growth record in plantations of Picea yezoensis and mortality for 14 years 2) Height growth record and mortality of under planting Picea yezoensis 3) Growth and mortality of seedlings at soil dressing 4) Growth pattern of young trees of Picea yezoensis 5) Tending plan for young trees of Picea yezoensis 6) Evaluation of the Ectomycrrhiza in nursery 7) A proposal for artificial regeneration of Picea yezoensis at wind damaged forests
