Abstract
To examine the potential of Alnus faurei for use in revegetation of disturbed steep hillsides, its growth and tree form were compared to those of traditionally used species: A. maximowiczii and A. hirsuta. The height and crown diameter of these three species, planted on disturbed slopes in a heavy snowfall region, were investigated for 9∼18 years. Also, the stem length and basal diameter of sprouts were compared between A. faurei and A. maximowiczii for 18 years. Results show that, more than the other two species, A. faurei favored crown enlargement over height growth; in spite of the tree height of 130 cm, the mean crown diameter reached 110 cm at the third growing season after the planting. At the ninth growing season, A. hirsuta showed a decline mainly by snow pressure injury; in contrast A. faurei became dominant with little damage, which apparently resulted from its tree form, with many sprouts per plant. A. maximowiczii showed intermediate traits. In conclusion, we recommend that A. faurei be used for revegetation of disturbed steep slopes in heavy snowfall regions.
