If there is heightened animal activity in an area it helps to know, especially if they are aggressive. We adjust where we go to avoid especially dangerous situations.

The National Park Service continuously posts updated guidance based on animal activity and will temporarily close areas of the park if there is an aggressive animal. This isn't being changed by the policy in the article.

Allowing arbitrary NPS employees talk to the public about people that may have died isn't required for any of this. To be honest, I am surprised that this new policy didn't already exist. It is very common practice to manage incident comms this way.

But aggressive animal presence is indicated by incident frequency not fatality frequency. It would seem that you still have access to the former.
