Subtropical evergreen broad-leaved forest (EBLF) is the zonal vegetation of the Chinese subtropical region, among which the most typical and widely distributed type is mid-subtropical EBLF. To explore how the 2008 ice-storm affected the short-term dynamics of mid-subtropical EBLF, we examined the community structure and species composition pre and post the ice storm of the 24 ha forest dynamics plot in Gutianshan. We found that although the DBH size class structure was highly consistent pre and post the ice storm, community level recruitment was low and mortality was high. Results of community dynamics analyses conducted at various grain size scales implied general depressions, despite the different rates of change between habitats. Species abundance and ABH (area at breast height) both decreased but species frequency and IV (importance value) did not change. Species in abundance, ABH, frequency and IV were highly consistent pre and post the ice storm. The results imply that the 2008 ice storm negatively impacted the short-term dynamics of the EBLF community in Gutianshan. The severity of impact was associated with stem DBH and topography. However, the community structure of this old-growth forest showed its considerable resistance to ice storm disturbance.
