Filter to support IUCN Red List Global Tree Assessment

(This is a placeholder issue, pending review with Andrew R, Malin R and others)

The IUCN Red List Global Tree Assessment group have published a checklist of accepted species. They are very interested in a Hosted Portal that collates tree data to aid in future Red List assessments. This requires the ability to search for "records that are identified to species that are listed in the GTS checklist".

This could be implemented in different ways, including e.g.:

• very specific (bool:isInGWT) to
• targeted audience ({...redListCheckists["1562fb95-b0a8-4fa3-adc7-79d872ac0da5"]...}) or
• more generically ({... speciesInChecklists["1562fb95-b0a8-4fa3-adc7-79d872ac0da5"] ... })

We would need to consider scalability, and criteria for selecting what checklists would be in/out knowing we couldn't scale to all checklists.
