The water deer habitat is the wetlands of the eastern central regions of China, situated in the Yangtze River Delta, on the banks of rivers and lakes, and also on the Korean Peninsula. Most often, you can see how water deer graze in high reed howls and on the green foothills, or during their resting on the soft soil of the fields that are plowed and seeded. Water deer will be able to swim some kilometers if there is a need to change the scenery or look for new pastures, migrating between the coastal islands.
