Hot Springs National Park surrounds the north end of the city of Hot Springs with a population of 33,000. Although some park boundaries are bordered by undeveloped forested lands, much of the park is adjacent to city streets and homes. These areas are subject to air pollution, exotic plant and animal species, and trash dumping. The park is an island of green in the developed downtown area. Resource inventories are currently underway to better prepare for the protection of the park's natural resources.
