Threatened Species – anative species that,while not presently threatened with extinction, is likely to become endangered in the foreseeable future if not given special protection and management efforts. Rare Species – anative species that, although not presently threatened with extinction, exists in such small numbers throughoutits range thatitmay become threatened if its presentenvironmental conditions worsen. Species Name: 1. What is its status? (See above.) 6. Why is it rare,threatened, or endangered? 2. Wheredoes it live? 7. Areanycurrentactions being taken to improve its chances of survival? 3. Whatdoes it look like? 8. What are some ways in which people can reduce or eliminate the threats to the survival of the species? 4. Whatis its habitat? 9. What other species depend on it? 5. Whatis the currentrange of its population? 10. Whyis it importantthatthis species sur- vive? (Giveseveral reasons.)
