Sint Eustatius: An island of the Dutch Caribbean The Kingdom of the Netherlands comprises the constituent countries of Aruba, Curacao, Sint Maarten, and the Dutch special municipalities of Bonaire, Sint Eustatius and Saba. Together they make up the Dutch Netherlands, located more precisely in the Lesser 2 Antilles with around 800 km and 300,000 inhabitants. Their natural heritage is rich and diverse, making them a ‘hot spot’ for biodiversity. The Dutch Caribbean boasts a range of unique, threatened and endangered habitats and species ranging from primary rain forest to magnificent coral reefs. The islands of Aruba, Bonaire and Curaçao alone are home to over two hundred endemic species and subspecies. The Dutch Caribbean islands form two distinct groups which are separated by more than 900 km of open water, but are also linguistically, culturally, geologically and ecologically divided. The Windward Islands include St Eustatius and Saba as well as St Maarten.

    The Biology and Distribution of Iguana delicatissima on St. Eustatius.

Cover photograph: Sub adult Iguana delicatissima captured in a garden by Great Estates. Abstract The Lesser Antillean Iguana (Iguana delicatissima) is native to the Lesser Antilles, a group of islands in the Caribbean Sea. The species is in serious decline, and has been extirpated on islands throughout its geographic range. Therefore I. delicatissima now is classified as endangered on the IUCN red list. A better understanding of these animals can help in effectively protecting them. With little known on the behaviour and distribution of the Lesser Antillean iguana on St. Eustatius, I spent 4 months studying this increasingly rare animal. In the search for iguanas approximately 80-84% of the island of St. Eustatius was investigated. To get an idea of the distribution, total population and biology of iguanas, 286 iguanas in total were caught, which includes work done by Thijs van den Burg. Of these iguanas 195 were beaded and 78 were temporarily marked. Nesting sites, hatchling sightings and the distribution of iguanas has been mapped. These maps illustrate fragmentation of the iguana population on St.
