A line that is marked at regular intervals and used to divide an area in which a species population will be counted. 2. A code created by extracting DNA from a small tissue sample and mapping a short DNA sequence from a specifi c part of the genome. 3. A frame (traditionally square) used in assessing animal or plant populations in a given area. 4. A list fi rst published in 1964 that identifi es species from around the world that are at risk. 5. A method used to estimate a species population and determine its distribution over a random area using a set of similar quadrats (shapes). 6. A time period in which a large number of species become extinct. 7. A species identifi ed as having no living specimens. 8. A species identifi ed by the IUCN as doing well and presenting no cause for concern or protection. 9. A species identifi ed by the IUCN as facing an extremely high risk of becoming extinct. 10. Every member of a species in an area is counted for assessment purposes. 11. A species identifi ed by the IUCN as having a high risk of becoming extinct and no longer living in the wild or in captivity. 12. The population of plants or animals is uncommon or infrequently encountered. 13. A species identifi ed by the IUCN with a possibility of facing population decline in the future and should therefore be monitored. 14. Indicates when a species is locally extinct and no longer found in an area it used to inhabit but is still found elsewhere. 15. A species identifi ed by the IUCN as likely to become endangered unless factors leading to its demise change. 16. The natural rate at which species extinction occurs. 17. A species identifi ed by the IUCN as no longer living in the wild but with examples of the species living in captivity. 18. A species that can exist in a wide range of conditions.
