Goat Island (Hawaii)

Goat Island, also known as Mokuʻauia, is a flat islet consisting of lithified dunes in Laie Bay on the northeast shore of Oahu, Hawaii.[1][2][3] The islet is separated from Malaekahana State Recreation Area by a 720 feet (220 m) channel of limestone reef shelf 1 metre (3.3 ft) underwater.[4][5][6]

Wildlife and conservation efforts

Goat Island is home to 16 native plant species, including the federally endangered Sesbania tomentosa.[4] It is a breeding ground for thousands of wedge-tailed shearwaters.

The islet contains invasive species, including black rats, fire ants, and big headed ants.[1][4][7] Black rats were first documented on the islet in 1967 with multiple eradication attempts in the 1990s and 2000s.[4] The elimination of the rats resulted in increased wedge-tailed shearwater reproduction.[4]

The dunes of the islet are a designated State Seabird Sanctuary, but its three beaches remain accessible to the public and attract many people annually.[4][8]
