In April 2002, the Government of The Bahamas declared the area a national park, conveying Moriah Harbour Cay National Park (MHCNP) to the BNT. The following year, when the boundaries were gazetted for Exuma, Moriah Harbour Cay and about half of the proposed area was excluded. BNT and supporters of the original proposal continued to advocate for the excluded area and eventually succeeded. The expansion of MHCNP was approved in 2015, as part of a national declaration by The Government of The Bahamas.
