St Vincent and the Grenadines boasts a diverse collection of biological resources. St. Vincent is rugged and mountainous with steep slopes and fertile yellow earth, volcanic ash and alluvial soils. The country has about 12,700 ha of tropical forests, including primary and secondary rainforest, palm brakes, elfin woodland, littoral woodland, dry scrub woodlands and mangrove forest. The significant tropical forests provide natural habitat for wildlife including the St. Vincent Parrot and other endemic species. The Grenadines, in contrast, consists of low dry islands surrounded by extensive coral reefs and sea grass beds.
