 According to a recent study, 90% of the Chinese giant salamanders' habitat was destroyed by the year 2000, and there are many human-related causes of such massive destruction.Because the salamander dwells in free-flowing streams, industrialization is a large problem for many stream-dwelling species.The construction of dams greatly disturbs their habitat by either causing these streams to dry up or to stand still, thus making it uninhabitable by the salamanders.
