An endangered species is a species whose population is so small that it is in danger of becoming extinct. Many countries have laws offering special protection to these species (forbidding hunting, banning their habitats from development, etc.) to prevent this.
Many of these laws are controversial. Typical areas of controversy include: criteria for placing a species on the endangered species list, and criteria for removing a species from the list once its population has recovered; whether restrictions on land development constitute a "taking" of land by the government, and the related question of whether private landowners should be compensated for the loss of use of their land; and obtaining reasonable exceptions to protection laws.
Endangered mammals:
Endangered birds:
- Ivory-billed Woodpecker (probably extinct)
- Lesser White-fronted Goose (Anser erythropus)
- Mauritius Parakeet (Psittacula echo)
Endangered reptiles:
Endangered amphibians:
- Palmate newt (Triturus helvetica)
- Israel painted frog (Discoglossus nigriventer)
- Italian spade-footed toad
- Desert slender salamander
Endangered flowering plants
About 6% of the 300,000 identified species are endangered due to overcollection or destruction of habitat, for example
- Saguaro cactus (Carnegia gigantea) of North America, due to overcollection
- Chilean wine palm (Juba chilensis), due to land clearance
- African violet (Saintpaulia ionantha), due to forest clearance
- King of the Paphs Orchid (Paphiopedilum rothschildianum) of Asia, due to overcollection
- Madonna lily (Lilium candidum) of Europe, due to overcollection
- Lobster claw (Clianthus puniceus) of Australia, due to overgrazing
