Overview

Landscape analysis reveals that reduced shoot harvesting accelerates bamboo forest spread across Japanese sites, suggesting abandoned management drives rapid forest expansion.

Key Points

To determine how environmental conditions and bamboo-shoot harvesting practices influence the expansion rates of Phyllostachys pubescens forests across distinct sites in Japan.
Analyzed historical vegetation maps from 1984 to 2001 in Hirasawa (Chiba Prefecture) and from 1986, 1996, 2000, and 2006 in Kofuki (Hiroshima Prefecture), Japan.
Calculated annual forest expansion rates and applied multiple linear regression across nine variables, including shoot shipment, original forest area, neighboring vegetation, road distance, slope inclination, and slope aspect.
In Hirasawa, shoot shipment positively influenced expansion, whereas adjacent short vegetation, slope northness, and baseline area acted as negative factors (R² = 0.683).
In Kofuki, distance from roads and slope eastness promoted expansion, while slope inclination suppressed it (R² = 0.942).
Phyllostachys pubescens forests expanded at an annual rate of approximately 2% in areas with decreased bamboo-shoot harvesting shipments.
