(ISNS) -- One of the thrills of visiting America’s national parks and wildlife preserves in the West is coming in contact with bears.
In most places, these encounters are harmless, but both the people and the bears can get hurt or even killed. Usually, it's humans' food that lures bears to approach people.
A study published in the current issue of journal Frontiers in Ecology and the Environment suggests that the National Park Service’s attempts to minimize those potentially hazardous meetings are working -- at least in Yosemite National Park.
