Section 1010.25  Criteria Used for Listing

a)         A species shall be included on the Official List when one or more of the following criteria exist:

1)         Species or subspecies designated as federally endangered or threatened.

2)         Species proposed for Federal Endangered or Threatened status that occurs in Illinois.

3)         Species that formerly were widespread in Illinois but have been nearly extirpated from the State due to habitat destruction, collecting, or other pressures resulting from the development of Illinois.

4)         Species that exhibit very restricted geographic ranges of which Illinois is a part.

5)         Species that exhibit restricted habitats or low populations in Illinois.

6)         Species that are significant disjuncts in Illinois, i.e., the Illinois population is far removed from the rest of the species' range.

b)         A species will be removed from the Official List if it no longer fulfills one or more of the criteria in subsection (a), except for a species that no longer fulfills the criteria because it no longer inhabits Illinois.  The determination will be made pursuant to Section 7 of the Endangered Species Protection Act [520 ILCS 10/7].
