The Red List of Ecosystem was developed by the International Union for Conservation of Nature (IUCN), the same entity that created the Red List of Threatened Species, a global framework to monitor the level of risk of animal and plant species.
The Endangered Species Act was enacted on Dec. 28, 1973, to establish protections for fish, wildlife and plants that are considered to be threatened or endangered.
A Regional Red List may be created by any country or organisation by following the clear, repeatable protocol. The process is as follows: All information relevant to a species conservation status is collected, including species distribution, population trend information, habitat, ecology and life history information, threats to the species and conservation measures currently in place.
