Abstract
<p>To evaluate the influence of various environmental factors on forest dynamics, we analyzed the relationship between dynamics parameters and environmental factors based on 1991–2013 monitoring data. Mortality was the largest in 1991–1993, when a severe typhoon occurred, for all species except Eurya japonica. In generalized linear model (GLM) of mortality including 1991–1993, 8 out of 14 species showed positive coefficient on strong wind influence. However, 5 species did in excluding the 1991–1993. During 1993–2013, more than 50% of damaged stems caused by the typhoon died. This was significantly larger than 16% for non-damaged stems. While, relative growth rate (RGR) for 11 out of 16 species increased after the typhoon. In GLM of RGR, 14 species showed negative coefficient on density of the canopy trees, and 8 species did on the air pollution. Mean RGR of stems was not significantly different among groups with or without damages caused by typhoon and/or forest pests. We concluded that strong winds would give the largest influence on population dynamics, at present. For some species, air pollution might influence on growth. Further monitoring is important to evaluate the changes of influence of various environmental factors on population dynamics of forests.</p>
