This study was conducted to clarify the characteristics of habitats and small rodent populations between remnant removed and left areas caused by different remnant treatment on forest floor in fired coniferous forest, Mt Gumbong, Samcheok, Korea, There were higher value of variables of understory coverage, snags, downed coarse woody debris (CWD) in natural restored area. Mean number of captured individuals and body weights of Apodemus peninsulae and Eothenomys regulus were more higher in remnant left area than in removed area, The differences in density and body weight of small rodents would be related with habitats between both study areas. The remove of remnant trees on the forest floor would not be good for small rodents. The more detailed and long-term researches would be needed for proper restoration in fired forest area.

This study aimed to investigate the differences in habitat environment and characteristics of small rodent populations with time elapse after thinning in Japanese larch (Larix kaempferi) plantations, Mt. Janggun, Gyeongbuk Province, South Korea. We found that there were significant differences in habitat environment, number of tree, shrub stems, coverage of overstory, midstory, rock and number of coarse woody debris (CWD) between thinned and unthinned forest stands. We captured four small rodent species. Total number of captured small rodent were higher in thinned stands. Male-to-female ratio of Apodemus agrarius, and A. peninsulae were both the highest in forest stand 3 year after thinning. The differences in number of captured and sex ratio of small rodents might be related to habitat environment between thinned and unthinned stands. Thus, thinning can provide good habitat for small rodents by developing understory vegetation and increasing CWD in Japanese larch plantations. These results suggest that forest management through maintenance of CWD and induction of midstory and understory vegetation after thinning is necessary to maintain small rodents diversity.
