The National Park Service, an agency within the United States Department of Interior, was established on August 25, 1916 by the National Park Service Organic Act, 16 United States Code. Said purpose is to "conserve the scenery and the natural and historic and the wildlife therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations." Title 16 addresses most of the major conservation laws that govern the National Park Service, including the establishment of individual parks. Specifically, Virgin Islands National Park was established by an act of the 84th United States Congress and signed into law by President Dwight D. Eisenhower on August 2, 1956.
General regulations for National Park Service areas may be found in Title 36 of the Code of Federal Regulations (CFR). Specific regulations for Virgin Islands National Park may be found in section 7.74 of Title 36 CFR, and in the Superintendent's Compendium which allows the Park Manager to expand on existing regulations for resource conservation and safety, etc.
Park Management also observes and enforces territorial laws and policies, such as the Department of Planning and Natural Resources (DPNR) fishing regulations. Some of these fishing regulations may be found in the DPNR Fisher's Information Guide.
In addition, to the conservation laws mentioned above, Park Rangers enforce Title 18 USC, criminal code of the United States, in order to maintain the public's welfare.
Remember, in an emergency dial 911.
