Abstract: Tracks of 9 species of mammals , Siberian weasels (Mustela sibirica) , yellow-throated martens(Martes flavigula) , Eurasian badgers (Meles meles) , Bengal cats ( Felis bengalensis) , wild boars ( Sus scrofa) , water deer ( Hydropotes inermis) , roe deer ( Capreolus capreolus) , Korean hares ( Lepus coreanus) and red squirrels ( Sciurus vulgaris) were recorded on the snow on eight 2 km transects in forests with similar vegetation features , but within fragmented and unfragmented landscapes in Mt. Chirisan National Park , Korea , from 1997 to 1999. All eight study sites have generally similar vegetation characteristics despite lying within a larger matrix of two different landscapes1 Nonetheless , there were significantly differences in density of snags , stems 6 - 10 cm diameter at breast height (dbh), stem > 50 cm dbh, canopy cover, and shrub coverage between fragmented and unfragmented forests. Nine species of mammals were recorded among 8 study sites in this snow tracking during 3 years. Significant differences were formed density between fragmented and unfragmented forests for 5 mammal species ; the others were evenly distributed. Of the 9 mammal species analyzed , 6 species exhibited one or more significant correlations with the landscape or vegetation variables in a stepwise multiple regression. Simple correlations between the abundance of snow tracks and the vegetation structure have limited value if not put into a local and regional habitat context. Distributions and dynamics of mammals in landscapes with fragmented and unfragmented forests ought to be examined more closely.
