Description
<p>Based on the concept of potential natural vegetation, indigenous tree species were planted to reforest a mining site in Kosaka, Akita Prefecture, Japan. The best growing plot among the planting areas was under the black locust forest, the soil of which was acidic and nutrients-rich. In contrast, the pH of the other planting sites was neutral. It is considered that the soil nutrient content is improving at all the planting plots. Both total nitrogen and total carbon have a positive correlation with the average volume index. The survival rate of trees planted in slag areas is higher than that in debris area, and does not depend on differences in moisture content between the debris and slag areas. The slag planting area had a more luxuriant appearance compared with the debris areas. The drying cold conditions due to the location and wind flow might be considered reasons for this appearance. Trees growing in the slag area have relatively longer shape. The relationship between total carbon and total nitrogen was linear for all plots. Fraxinus lanuginosa f. serrata showed better growth in soil with higher moisture and nutrient contents. Quercus crispula, showed greater sensitivity to soil moisture compared with Q. serrata.</p>
