POINT REYES STATION, CA - APRIL 19: Tule Elk graze on grass in a field at Point Reyes National Seashore Elk Preserve on April 19, 2015 in Point Reyes Station, California. As California enters its fourth year of severe drought, the dry conditions are being blamed for the deaths of nearly 250 Tule Elk in the past two years at the 2,600-acre Point Reyes National Seashore Elk Preserve. The heard has dropped from 540 to 286 this past year. The National Park Service is considering bringing in water as ponds and grasses in the preserve dry up. (Photo by Justin Sullivan/Getty Images)
