British Virgin Islands: Tortola Professional Review and Guide
"Tortola, the largest and most populated of the BVI, is the usual point of entry for visitors to the BVI. Road Town, on the south coast, is the administrative capital of the islands. The southern coast of Tortola is characterized by dry scrub land, and frangipani, tamarind, and loblolly grow well here. Most of the shipping and trading of the islands is done on this side of Tortola, while the northern coast hosts miles of secluded white sand beaches, mango and banana trees, and groves of sea grapes and manchineel trees.
The higher elevations of Mt. Sage and the ridgeline of the middle of the island trap more moisture than the coast and, as a result, the vegetation is much thicker. While not receiving enough rainfall to be technically called a rain forest, the center of the island possesses many plants commonly found there – philodendron, mahogany trees, ferns, and orchids.
