In Yosemite specifically, the bears and bobcats have been trying to push into the built up areas of the park forever. Of course this used to be because the human area was guaranteed food but now it's probably just curiosity. In Yosemite, the rangers are very good about not killing/injuring the wildlife and only driving them away. The typical ranger response is either paintball guns or pepper spray so the animals don't think humans are a threat, just that the food is not worth paintballs and pepper spray. With no humans to push them back, they'll take over the park scouring for the food that they expect to find. Most national parks operate on a strike system for the wildlife, Yosemite is the only one I'm aware of that will keep annoying a bear away even if it steals food every day for a week.
