BOISE (KTVB) -- Arguments in a lawsuit involving inadvertent trapping of federally protected Canada lynx and that could restrict trapping across much of Idaho are set for Tuesday in Boise.

The lawsuit says Idaho is violating the Endangered Species Act by allowing recreational trapping that sometimes catches the seldom-seen predator.

The Center for Biological Diversity and three other groups are asking the federal court to order Idaho to disallow lethal body-crushing traps and snares. The groups also want to limit the size of foothold traps in lynx habitat and require daily checks by trappers.

The groups say that at least four lynx have been trapped in Idaho since 2012.

The groups also say trapping in Idaho has increased, with about 650 licenses issued in the 2001-2002 season to more than 2,300 last winter.
