What does relict mean in conservation?
A relict is a species that remains from a group largely extinct. It can be identified according both to a phylogenetic analysis and to a fossil record of extinction.
What is a relict plant community?
A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole.

What conservation status does New Zealand use?
In many countries, species listed as threatened automatically receive legislative protection from hunting, habitat destruction and other threats. In New Zealand, there’s no direct link between conservation status and legal protection.
What are Neoendemic species?
Neoendemism is one of two sub-categories of endemism, the ecological state of a species being unique to a defined geographic location. Specifically, neoendemic species are those that have recently arisen, through divergence and reproductive isolation or through hybridization and polyploidy in plants.
How many species are threatened with extinction in the world?
• 16,928 plant and animal species are known to be threatened with extinction. This may be a gross underestimate because less than 3% of the world’s 1.9 million described species have been assessed for the IUCN Red List of Threatened Species.
Are there any extinct animals in the world?
One of the extinct animals., Voay robustus is an extinct species of crocodile from Madagascar and it includes only one species of crocodile that is V. robustus. There was subfossil for this species including complete skulls as well as vertebrae in Ambolisatra and Antsirabe. The name of the species comes from the Malagasy word for crocodile.
How are species classified on the IUCN Red List?
The IUCN Red List Categories and Criteria are an objective system for classifying species according to their risk of global extinction. There are nine categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient, and Not Evaluated.
What makes a species endangered under the ESA?
Under the ESA, species may be listed as either endangered or threatened. “Endangered” means a species is in danger of extinction throughout all or a significant portion of its range. “Threatened” means a species is likely to become endangered within the foreseeable future.
