一般講演（ポスター発表） P2-126 （Poster presentation）
A landslide is one of the major disturbances in terrestrial ecosystems globally, and frequently occurs due to several drivers, such as heavy precipitation and earthquake. A lot of studies have addressed how local vegetation recovered after landslide disturbance. However, the lack of integrations of the case studies have prevented us from developing model to predict the revegetation rates after landslide globally. Thus, an integrating approach across world-wide landslide studies is required to understand general patterns of post-landslide revegetation. In this study, to unravel biotic and abiotic factors that influence the revegetation rate after landslide disturbance, we conducted a meta-analysis of systematically-gathered empirical studies. To analyze effects of biotic and abiotic factors on revegetation rate after landslide without control treatments, we focused on the magnitude of decreases of revegetation rates along with the time after landslide occurrence. As a result, the magnitude of decreases of revegetation rates significantly differed among climate zones and slope gradients. Our finding suggests that climate conditions, such as temperature and precipitation, and/or regional species pools could influence revegetation rate after landslide disturbance. This study will provide a worthful insight for management planning of restoration after landslide.
