In the railway forest that the Ebetsu government plans to convert into an urban park, there are two ponds inhabited by Ezo salamanders (Hynobius retardatus). For the sustainable use of this forest in the future, it has been proposed that the forest be developed as a nature reserve/park that people can visit for relaxation. In this study, the water quality of the two ponds was investigated from June 2017 to October 2018 to evaluate the water environment as well as the growth and development of the salamanders. The results of the pond water evaluation showed eutrophication and low dissolved oxygen, which can hinder the growth of aquatic organisms. However, favorable growth conditions for salamanders were confirmed in both ponds.
