FILE - in this April 19, 2005 file photo, a Canada lynx heads into the Rio Grande National Forest after being released near Creede, Colo. Wildlife advocates want a federal judge to force the government to move more quickly on a recovery plan for imperiled Canada lynx. The U.S. government declared the snow-loving big cats a threatened species across the Lower 48 states in 2000. But officials haven&#039;t come up with a mandated recovery plan.
