All of the known populations of Z. lucayana are in a 6.5 kilometres (4.0 mi) by 100 metres (330 ft) strip of coastal scrub dominated by Coccoloba uvifera (sea grape) on the east coast of Long Island. In the early 2010s Z. lucayana was found in three major populations (240 to 400 adult plants each) at the settlements of Buckley's, Petty's, and Hamilton's, and two minor populations of 10 adult plants at Galloway Landing and 20 adult plants at Mangrove Bush, for a total of about 980 adult plants. The coastal scrub habitat is 1 square kilometre (0.39 sq mi) in area, with the Z. lucayana plants covering just 0.06 square kilometres (6.0 ha; 15 acres) of the habitat.[5]
