We used Generalized Linear Models (GLMs) to model the field sign abundance of Korean water deer. To assess the topographical differences in field signs of water deer within the home-range scale, the model included topographical variables, habitat variables and two-way interactions between topographic and habitat variables.
The abundance of feces ([chi square] = 151.56, p < 0.001) and total ([chi square] = 172.37, p < 0.001) field signs of Korean water deer were significantly different between topographies.
Most of the winter field signs of Korean water deer were observed on the ridge.
The best models of winter field sign abundance of Korean water deer in the temperate forest had an Akaike weight ([omega]) of 0.22-0.53.
For Korean water deer, understory vegetation, shrub and graminoid would be good cover and food resources.
In this study, the impact of habitat variables on winter abundance of field signs of Korean water deer varied with topography.
In the present study, Korean water deer selected the site with more shrub and graminoids coverage on the ridge during the winter period.
Understory and midstory vegetation coverage, forage and topography would be important ecological factors affecting winter field sign abundance of Korean water deer. In general, the present study seems to indicate that, while Korean water deer show high ecological plasticity, they are selective with respect to potential winter foraging sites.
