- 1IUCN- international union for conservation of nature-Established by the UN
-Membership of 1400 governments and non-governmental organizations
-16,000 Scientists help with the collection and handling of data - 2IUCN red list-Extinct
-Extinct in the wild
-Critically endangered
-Endangered
-Vulnerable
-Near Threatened
-Least Concern - 3Extinct-No known individuals remain
-Yangtse River Dolphin is extinct, due to fishing and industrialisation in China - 4Extinct in the wild-Only survive in captivity
-Simitar-horned Oryx, extinct in the wild as a result of climate change and being hunted for its horns. - 5Critically endangered-Extremely high risk of extinction in the wild
-Black Rhino - 6Endangered-High risk of extinction in the wild
-Snow leopard, due to poaching and competition with other leopard species which have now moved further up north due to climate change. - 7Vulnerable-High risk of becoming endangered
-Reticulated Giraffe, due to habitat loss and hunting loss and hunting for their meat - 8Near Threatened-Likely to become endangered in the near future.
-European otter, due to mainly pollution. - 9Least ConcernAt lowest risk of becoming endangered.
- 10Criteria used to categorise species-Rate of population decline
-Area of habitat
-Number of areas where found
-Number of mature adults
-Probability of extinction - 11Criteria that is important in conserving species-Species in habitats under particular threat
-Evolutionary uniqueness
-Endemic species
-Keystone species
-Flagship species
-Degree of population dispersal - 12Species in habitats under particular threatKey species in habitats that are threatened may be assessed for categorisatiom. Their status may include the status of the rest of the community of species.
-Tropical rainforest - 13Evolutionary uniquenessSpecies that have a high degree of evolutionary uniqueness may be categorised. Evolutionary Distinct and Globally Endangered (EDGE) species may have few close relatives.
-Bactrain camel - 14Endemic speciesEndemic species aren't found in any other area so if there is a change in the threat to its survival and it dies out locally there will be no surviving populations elsewhere.
-All lemurs are endmic to Madacascar. - 15Keystone speciesA keystone species has an important role in maintaining the ecological structure of a community.
African Bush Elephant - very important for seed dispersal, keeping paths open and keeping water holes open. - 16Flagship speciesSpecies that have a high public profile. Raising support to protect them may have a wide benefit for widlife conservation.
-Bengal tiger - 17Degree of population dispersalWhen the global population of a species is fragmented into a number of isolated populations it is important to ensure that viable local populations are maintained.
