Wherever you want good shelterbelts, you must firstly establish low tree belts of pioneer broad-leaved trees. And, in several years, after the completion of the belts, you will be able to create high tree belts among or behind them. On late September in 1965, the idea was adapted on peat-bog of reed, Phragmites communis, at Toikanbetsu, northern Hokkaido. Afforestation on peat-bog needs drainage. And planting mounds were rolled up with bog-bulldozer. On the mounds wood-cuttings of Hakkaido poplar, Populus maximowiczii, and a native willow, Salix sachalinensis, were planted, because the method is only suitable for planting to such a land-preparation. After one year few were damaged by freezing and drying. The renewed shoots out of wood-cuttings have grown vigorously and attained to their maximum height of 0.7m and standard 0.3m in Populus, and 1.7m and 1.0m in Salix, respectively. Effective low tree belts will be promised within ten years.
