The purposes of this study were to evaluate ecological characteristics (density, distribution, habitat patterns)of wildlife species of Korea and to recommend and implement an integrated process for improved endangered species management system of Korea. Density and distribution of twelve game species, Ring-necked Pheasant(Phasianus colchicus), Rufous Turtle Dove(Streptopelia orientalis), House Sparrow(Passer montanus), Spot-billed Duck(Anas poecilorhyncha), Mallard(Anas platyrynchos), Common Teal (Anas crecca), Jay(Garrulus glandarius), Korean Hare(Lepus coreanus), Water Deer(Hydropotes inermis), Squirrel(Sciurus vulgaris)and Wild Boar (Sus scrofa)were analyzed in 405 randomly selected quadrats throughout the country. Population sizes of ring-necked pheasant and rufous turtle dove were stable until 2001 and then declined slightly in 2003, whereas population density of house sparrow has decreased continually since 1982. We suggest that habitat destruction and a large amount of insecticide spray have affected the survival of house sparrow population. Spot-billed duck, mallard and common teal have declined in numbers since 1990s because of human disturbance and alteration of wetland habitats of Korea.
This study analyses quantitatively the association between habitat characteristics and otter distribution. There was a strong positive correlation between habitat quality and an index of the number of spraints. Otters occurred in high quality fresh water habitats with high bankside vegetation cover, unpolluted, with low or very low human disturbance and surrounded by natural forests. The areas supporting otters also had relatively more bankside natural vegetation, a greater density of trees, and more potential security sites for which vegetation, tree and rock appeared particularly important. In Korea the surviving population is broken into small fragments which may not be viable in these habitats. We suggest that recovery plan for the species is urgently needed to survive the otters in the country in the future.
