The environment of Saba is mainly composed of woodland forest with ferns and damp soil, and many mango trees. There used to be forests of Mahogany trees until a hurricane in the 1960s destroyed many of the trees. The Mahogany trees are considered at risk of going extinct on the island. Visitors refer to Saba's forests as "the Elfin Forest" because of its high altitude mist and mossy appearance. Since then there has been a woodland reserve created and aptly named "Elfin Forest Reserve". Saba's lush plant and animal wildlife are diverse and are looked after by the Saba Conservation Foundation.
4.3 km southwest of Saba is the Saba Bank, a large submerged atoll of rich biodiversity, and a prime fishing ground, particularly for lobster.
