(Guidelines and Criteria Section B/ Ecological Criteria) Nominated areas must conform to at least one of the eight ecological criteria. Describe how the nominated site satisfies one or more of the following criteria. (Attach in Annex any relevant supporting documents.)


The National Park is home to a number of distinct habitats based on the higher moister Quill and the lower drier Boven sectors, as well as affected by the windward and leeward influence on climate. This has led to a relatively high number of species present in the habitats:

  • Evergreen seasonal forest (110ha)
  • Pioneer forest (10ha)
  • Elfin forest (5ha)
  • Montagne thickets (25ha)
  • Semi-evergreen seasonal forest (35ha)
  • Deciduous seasonal forest (25ha)
  • Evergreen bush land (5ha)
  • Rock pavement vegetation (5ha)
  • Seasonal thorny woodland (320ha)

Critical habitats:

Evergreen seasonal forest (highest biodiversity on St Eustatius, Iguana delicatissima, Alsophis rufiventris).

Elfin forest (rare habitat with wild balsam and epiphytic leaf mosses, tree fern Cyathea spp., some orchid species only found in this habitat, considered very vulnerable to human activity) Montagne thickets (Alsophis rufiventris) Semi-evergreen seasonal forest (several species of orchid including Brassavola cucullata, this type of forest is typical to the Caribbean but has been destroyed on a wide scale to make way for buildings on other islands, Iguana delicatissima, Alsophis rufiventris, Falco sparverius) Deciduous seasonal forest (Iguana delicatissima, Alsophis rufiventris, Falco sparverius) Evergreen bush land and rock pavement vegetation (10ha.

Seasonal thorny woodland (endemic Ipomoeia sphenophylla and cactus Opuntia triacantha, some species of orchid only found in this habitat, Hylocereus trigonus, Orthorhyncus cristatus, Falco sparverius, several sea bird species nesting on steep slopes including Phaethon aethereus and A. lepturus, Iguana delicatissima, Alsophis rufiventris).
