Range Comments
A Western Fence Lizard population was detected near Perma in 2002 by a biology student at the Salish Kootenai College (Werner 2008). The closest known location of another Western Fence Lizard population is 240 km to the west in eastern Washington (St. John 2002). It is currently uncertain whether this population is an isolated native population or an introduced population.
