User:Pcr&img37/Common watersnake

Geographic range[edit]
The common watersnake is found throughout eastern and central North America, from southern Ontario and southern Quebec in the north, to Texas and Florida in the south. In 2007 a small introduced population was discovered in California, where its congeneric species N. fasciata has been introduced since at least 1992. Both are considered invasive species likely to compete with native giant garter snake Thamnophis gigas.
