The site itself is covered by white mangrove (Laguncularia racemosa), gumbo-limbo (Bursera simaruba), white poisonwood (Cameraria belizensis), silver palmettos (Thrinax sp.), cabbage palms (Roystonea oleracea) and a variety of shrubbery.
Like its cousin Florida Poisonwood (Metopium toxiferum), it produces urushiol in its bark, which can cause contact dermititis on one's skin when touched; therefore live trees and fresh cut logs should be handled carefully.
The island is covered in a forest of just four tree species: short-leaf fig (Ficus populnea var. brevifolia), pigeon plum (Coccoloba diversifolia), mastic (Sideroxylon foetidissimum), and poisonwood (Metopium brownei).
