I serve on the invasive plant listing committee for the Florida Exotic Pest Plant Council. To list a plant species as invasive in Florida, our rules require at least one voucher from a natural area in which the plant has become established and is displacing native flora. The means by which populations of invasive plant species become established is important to us with regards to early detection and rapid response as well as expanding our understanding of the source of introduction (hurricanes, nursery industry, inadvertent introduction, escapes from gardens, etc.).

Hi Quentin,

Thank you for your effort in putting forth these welll thought out proposals. At various times I have heard discussions on the inadequecy of establishmentMeans. Your work encapsulates the problem well. 
One of the things that helps when proposing to add a Darwin Core term is demonstrating that there is a community that needs it. Can you tell us who has a demonstrated need to share this information? Anyone out there who has this interest is also welcome to share that here to provide evidence of demand from more than one group, project or individual.

Cheers,

John

I've been working on a proposal to improve Darwin Core for use with invasive species data.


The proposal is for a new term "origin" and suggested vocabularies for establishmentMeans and occurrenceStatus.

I'd welcome your feedback on the proposal.

From my perspective it provides some needed clarity on the establishmentMeans and occurrenceStatus fields, but also adds the origin that is needed for invasive species research and for conservation assessments.

I'm not sure of the best way to discuss this, but if you have concrete proposals for changes you might raise them as issues on GitHub, as well as mentioning them here.

Regards
Quentin
