Default Place Check Lists
When you create a place, you have the option to mark “check lists allowed”. Doing so will create a default check list for the place. Place check lists behave very much like original life lists in that they include auto-listing functionality from research grade observations made within the place. Likewise, people can manually create and destroy listed taxa independent of the observations made in the place. The observation stats are filled by observations made within the place.
Listed taxa on place check lists also store “establishment means” (e.g. native/introduced) for species in that place which is used throughout the site. Likewise, the listed taxa on standard place default checklists also determine the "presence places" in an atlas. The existence of an atlas for a species disables auto-listing functionality for that species on default checklists.
Other Place Check lists
In addition to the default place check list, places can have other check lists. They can be restricted to a higher-level taxon and they can be marked as “comprehensive” from the list edit page to indicate that all species in that higher-level taxon for the place are included in the list. Like the default place checklist, they also have auto-listing functionality.
