SQS

A score given to a species based on its conservation score. The scores are used to create the Species Quality Index (SQI) score for a sample.

0 = Not native. Not all of these are listed as not native in the status review: some are given no score, but the text says that they are thought not to be native. It is not always possible to tell whether a species is native or whether the reviewer thought it is native.

1 = Species that are not rare or scarce. Includes those that are New to Britain.
