WHITEBARK PINE // With large seeds high in fats, whitebark pine trees are an important source of food for many animal species. Red squirrels and Clark's nutcrackers usually harvest the lion's share of whitebark pine seeds. Grizzly bears and black bears raid squirrel caches that contain whitebark cones to get pine seeds, one of their favorite foods. // http://nrmsc.usgs.gov/research/whitebar.htm
