Can i have some help with a report about Hot springs national park in Arkansas, or just some general info?

Im doing a report on Hot springs national park in arkansas, and i was wondering, what are some ways it helps protect the ecosystem and animal community. The park is surrounded by a city, so i have that it keeps the city from developing the land, but what else? It protects the springs, but i dont know exactly what it does to protect the wildlife and stuff. You dont have to know much about Hot springs national park, but do you have info on how other national parks protect stuff? Thank you for any answers. And for any cat lovers out there, HURRAY!!!
