List of endangered plants

(Redirected from Endangered plants)

In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species.[1] Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN.

  • 66,406 extant species have been evaluated
  • 61,035 of those are fully assessed[a]
  • 34,588 are not threatened at present[b]
  • 26,276 are threatened[c]
  • 174 are extinct or extinct in the wild:
    • 129 extinct (EX) species[d]
    • 45 extinct in the wild (EW)
    • 569 possibly extinct [CR(PE)]
    • 48 possibly extinct in the wild [CR(PEW)]

Endangered (EN) species are considered to be facing a very high risk of extinction in the wild.

For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered.

Additionally 1674 plant species (7.6% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".[3]
