## Codes used in Status columns in tables below

[edit]

* Extinct (EX) – No known living individuals
* Extinct in the wild (EW) – Known only to survive in captivity, or as a naturalized population outside its historic range
* Critically endangered (CR) – Extremely high risk of extinction in the wild
* Endangered (EN) – Higher risk of extinction in the wild
* Vulnerable (VU) – High risk of extinction in the wild
* Near threatened (NT) – Likely to become endangered in the near future
* Conservation Dependent (CD)  – Low risk; is conserved to prevent being near threatened, certain events may lead it to being a higher risk level
* Least concern (LC) – Very Low risk; does not qualify for a higher risk category and not likely to be threatened in the near future. Widespread and abundant taxa are included in this category.
