Presence and distribution information

For each species (and lower taxa) in the Dutch Caribbean Species Register we have noted on which island(s) they have been recorded. Per island, we have also judged its presence status. The following categories are used and can be searched on:

- Indigenous (code 1): species/taxon is indigenous to the island (native species, and established new arrivals and vagrants by natural means).

- Introduced (code 2): species/taxon has been introduced to the island by humans, and is now reproducing there. Includes incidental escapes/imported species.

- No longer present (code 0): species/taxon used to be present (established or frequently occurring) on an island, but is now no longer present or occurring due to e.g. local or global extinction or extirpation/eradication.

Available options for the Dutch Caribbean as a whole (instead of per island) are:

- Extinct - globally (code 0): species/taxon is globally extinct. These taxa are also registered as “No longer present (0)” on the island(s) where they used to occur.

- Data deficient (code 3a): species/taxon reported for the islands, but there is inconclusive or no evidence at all that the report is correct. E.g. species mentioned once in doubtful source, without collection material as evidence.

- Incorrectly reported (code 3b): species/taxon reported for the islands, but incorrectly, e.g. as result of a wrong identification.

- To be expected (code 3c): species/taxon not reported for the islands yet, but expected to occur in the near future on the basis of reports in nearby areas/islands (e.g. marine species with a Caribbean-wide distribution, migrant birds that are known from nearby islands, or invasive species which disperse rapidly in adjacent areas).

- Incorrectly used name/auct. (code 3d)
