BOTANY WITH BASICS OF HYDROBOTANY (AQUATIC PLANTS OF UKRAINE) - B.Ye. Yakubenko - 2011

XII. CONSERVATION OF PLANTS AND THEIR PLANT COMMUNITIES.

Rare species of aquatic and wetland plants [96a].

Rarity categories.

Category 0 - Extinct: species for which, after repeated surveys conducted in typical habitats or other known and potential localities, there is no longer any evidence of their survival in the wild.

Category I - Endangered: species facing a very high risk of extinction in the wild, the survival of which is unlikely if the causal factors operating on their status continue to operate.

Category II - Vulnerable: species expected to move into the endangered category in the near future if the causal factors acting on their status continue to operate.

Category III - Rare: species with small populations that are not currently endangered or vulnerable, but are at risk.

Category IV - Indeterminate: species known to be endangered, vulnerable, or rare, but for which there is insufficient reliable information to determine their status.

Category V - Data Deficient: species that could potentially be assigned to one of the above categories, but due to a lack of comprehensive data, their status remains uncertain.

Category VI - Recovered: species whose populations are no longer a cause for concern thanks to conservation measures implemented, but which are not yet subject to harvesting and require ongoing monitoring.
