16. A park superintendent may temporarily prohibit the practice of an activity or deny access to part or all of the park:(1) if human safety is in jeopardy;
(2) if facilities have reached or exceeded maximum capacity;
(3) if there is risk of damage to the environment;
(4) if there is specific need to protect a wildlife or a plant species.
A park superintendent shall post a notice stating any such prohibition at the reception station or at any other place in the park where it may be easily read by any person who enters the park. He shall give a copy thereof to any interested person.
It is the responsibility of a park superintendent to have such prohibitions indicated on signs.
