Wetlands are a paradise for living creatures. In particular, more than 350 kinds of native plants grow in the Senjogahara marshland, which is also famous as an observation site among bird watchers. It is not only wild birds that make this land their home. The well-maintained, superior natural environment is also inhabited by animals such as the Japanese serow, Japanese dormouse, Asian black bear, and Japanese macaque. Sockeye salmon, rainbow trout and brown trout are found in the lakes, where many people enjoy fishing.
