Guadeloupe

Indigenous or undetermined. Taxon present in a broad sense in the geographical area under consideration, i.e., native taxon or taxon not known to belong to one of the other categories. The lack of knowledge thus benefits the indigenous. Indigenous means: taxon that originated in the geographical area under consideration and that has developed naturally there without human contribution, or taxon that arrived there without human intervention (intentional or not) from an area in which it is indigenous. (NB: excluded hybrids of which at least one of the parents is introduced in the considered area). All taxa categorized as
