Abstract
: The Darwin Core term `degreeOfEstablishment` provides information about degree to which an Organism survives, reproduces, and expands its range at the given place and time.. The Degree of Establishment Controlled Vocabulary provides terms that should be used as values for `dwc:degreeOfEstablishment` and `dwciri:degreeOfEstablishment`.

## 1 Introduction
This document includes terms intended to be used as a controlled value for Darwin Core terms with local name `degreeOfEstablishment`. 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](https://tools.ietf.org/html/rfc2119).
## 2 Use of Terms
Due to the requirements of [Section 1.4.3 of the Darwin Core RDF Guide](http://rs.tdwg.org/dwc/terms/guides/rdf/#143-use-of-darwin-core-terms-in-rdf-normative), term IRIs MUST be used as values of `dwciri:degreeOfEstablishment`. Controlled value strings MUST be used as values of `dwc:degreeOfEstablishment`.

<td>Considered native and naturally occurring. See also "category A" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>Individuals in captivity or quarantine (i.e., individuals provided with conditions suitable for them, but explicit measures of containment are in place).</td>

<td>Individuals in cultivation (i.e., individuals provided with conditions suitable for them, but explicit measures to prevent dispersal are limited at best).</td>
<td>Examples include gardens, parks and farms. See also "category B2" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>For example, fish stocked for angling, birds for hunting. See also "category B3" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>For example, frost-tender plants sown or planted in a cold climate. See also "category C0" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>Trees planted in the wild for forestry or ornament may come under this category. See also "category C1" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>Offspring are produced, but these either do not survive or are not fertile enough to maintain the population. See also "category C2" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>The population is maintained by reproduction, but is not spreading. See also "category C3" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>Self-sustaining population outside of captivity or cultivation, with individuals surviving a significant distance from the original point of introduction.</td>
<td>The population is maintained by reproduction and is spreading. See also "category D1" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>Self-sustaining population outside of captivity or cultivation, with individuals surviving and reproducing a significant distance from the original point of introduction.</td>
<td>The population is maintained by reproduction, is spreading, and its progeny are also reproducing and spreading. See also "category D2" in Blackburn et al. 2011. <ahref="https://doi.org/10.1016/j.tree.2011.03.023">https://doi.org/10.1016/j.tree.2011.03.023</a></td>
<td>Fully invasive species, with individuals dispersing, surviving and reproducing at multiple sites across a spectrum of habitats and geographic range.</td>
