The Nishioka Park is a location of rich nature which centers around a pond and consists of marshland and the forest of Tsukisamu River, and its upper river basin.
A sight of marsh plants such as giant skunk cabbage, and dragonflies, fireflies, etc. can be seen in the environment blessed with water and greenery along with many other plants and animals. This park also serves as a one of the main habitats in Hokkaido for many types of wild birds.
In the Meiji Era, the main pond was created by damming up the Tsukisamu River to be used for water service facilities of the old army.
The management of the area was eventually passed over from Toyohira City to Sapporo, and finished its services as water source facility in 1971.
Besides being used as a waterfront park, this area is also widely loved as an area for bird watching or a place of natural observation.
In order to preserve this precious nature for years to come, a special classification change as a scenic zone was made to this park in 2008.
This was built in the Meiji Era, for the old army to use as their source of water.
It was designated as a registered cultural asset of the country on September 14, 2001.
These are one of the types of insects that represent life around the Nishioka waterfront area. They can be observed near the source of a stream during the nights around July.
The Nishioka Park has the most kinds of dragonflies living round a single lake in Hokkaido, and 49 kinds of dragonflies are confirmed.
