Abstract
The Darwin Core term establishmentMeans provides information about whether an organism or organisms have been introduced to a given place and time through the direct or indirect activity of modern humans. The Establishment Means Controlled Vocabulary provides terms that should be used as values for dwc:establishmentMeans and dwciri:establishmentMeans.

1 Introduction

This document includes terms intended to be used as a controlled value for Darwin Core terms with local name establishmentMeans. For details and rationale, see Groom et al. 2019. Improving Darwin Core for research and management of alien species. https://doi.org/10.3897/biss.3.38084

1.1 Status of the content of this document

In Section 4, the values of the Term IRI, Definition, and Controlled value are normative. The value of Usage (if it exists for a given term) is normative. The values of Term Name are non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. Label and the values of all other properties (such as Notes) are non-normative.

1.2 RFC 2119 key words

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119.

2 Use of Terms

Due to the requirements of Section 1.4.3 of the Darwin Core RDF Guide, term IRIs MUST be used as values of dwciri:establishmentMeans. Controlled value strings MUST be used as values of dwc:establishmentMeans.

Label native: reintroduced
Definition A taxon re-established by direct introduction by humans into an area which was once part of its natural range, but from where it had become extinct.

Label introduced (alien, exotic, non-native, nonindigenous)
Definition Establishment of a taxon by human agency into an area that is not part of its natural range
Notes Organisms can be introduced to novel areas and habitats by human activity, either on purpose or by accident. Humans can also inadvertently create corridors that breakdown natural barriers to dispersal and allow organisms to spread beyond their natural range.
Controlled value introduced
