Hundreds of mountain goats in Olympic National Park, WA have become so addicted to the salt found in human urine and sweat that they are an aggressive menace to national park visitors, charging at hikers and trampling vegetation. They have a taste for salt and minerals in human urine, and sweat on clothes and backpacks, according to officials.

The solution to this problem? Airlift 375 of the non-native grumpy animals to more remote areas closer to their natural habitat where they will be less of a nuisance.

“Mountain goat relocation will allow these animals to reoccupy historical range areas in the Cascades and increase population viability,” US Forest Service Wildlife Biologist Jesse Plumage said in a statement.

Last Fall, teams using helicopters, tranquilizer darts, and net guns captured 115 goats during a two-week period, releasing 98 back into the wild. There are a further two operations planned this summer that will impact Olympic National Park visitors, the first is July 8-19 and the second is August 19-30.

Last year the operation saw crews capture goats from ridges and rocks within the park before being airlifted to a staging area, driven to another part of the North Cascades, and then airlifted in crates before being released back into the wild.
