The non-poisonous and very rare Narrow-headed Gartersnake lives in the cool, clear waters of Oak Creek. Adults have a dark brown or grey, stripe-less back and recognizable “narrow” head. Juveniles are tan or red with dark spots. Their rapidly declining populations may be attributed to the introduction of non-native predators, including crayfish, fish, and bullfrogs; habitat alteration; high recreational use; and poor water quality.
