It’s been discovered: The unmarked storage area where Point Reyes National Seashore officials temporarily keep tule elk antlers before placing them in the field, outside the gaze of would-be poachers. Park staff found a skull missing from the area, which is off limits to the public, on Aug. 20, and reported it to park rangers for investigation. Now, the park will need to find a new location for the elk antlers and skulls. “We’re going to need somewhere else that’s a little more off the beaten path,” said Dave Press, the park’s wildlife ecologist. Bull elk shed their antlers in the early spring; known as “sheds” once they hit the ground, the antlers are more than relics: they provide a valuable source of calcium and other nutrients for creatures living in the park. Visitors occasionally pick them up to keep as souvenirs, and poachers collect them to sell on the black market. So Mr. Press and his staff collect the sheds from high-visibility areas of the park, storing them until they can distribute them across more remote areas. In 2015, the park cited two men suspected of poaching elk sheds as they arrived at a Marshall boat launch in an inflatable boat full of the antlers. Mr. Press said poachers remain active in the park, though they face up to six months in jail and a  fine of up to $5,000. “They know when the antler drop is, they know how to avoid law enforcement, they wear camouflage, they use spotting scopes,” he said.
