It is not legal to operate any drone from within a National Park Currently, so this shouldn't be much of an issue there. As for wildlife - http://www.nrcresearchpress.com/journal/juvs http://www.nrcresearchpress.com/journal/juvs - I saw a presentation by Dr. David Bird on the use of small drones / UAS for wildlife research and he said that his team had found them to be drastically less disruptive than other methods of research, and that animals became acclimatized to their presence very quickly. Obviously, that doesn't really answer the question as to wether there will be long term effects, but it seems that most animals get used to them/don't mind.
