Abstract

In Japan, forestry seedling producers and production have been declining since the 1960s. However, clear-felling areas expanded throughout the 2010s and a steadier supply of seedlings for reforestation is required. In 2017 we conducted interviews with all five seedling producers who produced container seedlings in Ibaraki Prefecture to clarify the actual conditions of seedling production, including the production processes of bare-root and container seedlings, and the challenges of sustaining a steady supply of seedlings. Results are as follows: (1) they considered seedling production a main business using between 1.4 and 4.3 ha of their land, and produced 56,000 to 200,000 stems in their nurseries (0.5 to 2.0 ha), (2) they produce bare-root and container seedlings according to demand, (3) they want to increase the production of container seedlings, which is relatively easy, but securing labor is an important issue, and (4) they consider securing a labor force to be an important issue in the future, and that container seedling production, which is relatively easy to manage, is effective in solving that issue. Clarifying the outlook for the demand for whole seedlings, developing production technology and solving the problem of securing labor are necessary to ensure a steady supply of seedlings.
