Abstract

The purpose of this study was to examine the characteristic ideas of local bioresource utilization through the analysis of formative processes and factors for the development of shelterbelt plantations on Izu-Oshima Island. Shelterbelt plantations in Japan have rich diversity and are a good index for detecting long-standing customs of the people due to the meteorology, ecosystem, and socioeconomic factors of each locality. Grid-shaped shelterbelts, which mainly consist of 50-m-long Camellia japonica queues, are observed on Izu-Oshima Island. The two-row C. japonica shelterbelt suggests the economic significance of this plant for residents. Another shelterbelt planted with alternate Prunus lannesiana and C. japonica trees indicates the resource-utilization literacy of the older generation. A C. japonica shelterbelt established around 2000 reflects the influence of traditional practices on current livelihoods. The close relationship between C. japonica and people's livelihoods on Izu-Oshima Island is described.
