The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
A conservation-dependent species is a species which has been categorized as "Conservation Dependent" ("LR/cd") by the International Union for Conservation of Nature (IUCN), as dependent on conservation efforts to prevent it from becoming endangered. A species that is reliant on the conservation attempts of humans is considered conservation dependent. Such species must be the focus of a continuing species-specific and/or habitat-specific conservation program, the cessation of which would result in the species qualifying for one of the threatened categories within a period of five years. The determination of status is constantly monitored and can change.
An IUCN Red List Critically Endangered species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be Critically Endangered.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.

Ictinogomphus ferox, commonly called the common tiger or the common tigertail, is a species of dragonfly in the family Gomphidae. It is found in Angola, Botswana, Central African Republic, the Democratic Republic of the Congo, Ivory Coast, Ghana, Guinea, Kenya, Liberia, Malawi, Mozambique, Namibia, Nigeria, Senegal, Somalia, South Africa, Tanzania, Togo, Uganda, Zambia, Zimbabwe, possibly Burundi, and possibly Ethiopia. Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs.
Ictinogomphus is a genus of dragonflies in either the family Gomphidae or Lindeniidae. They are medium to large, yellow and black with clear wings. Species occur in Africa, Asia and Australia.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Ictinogomphus rapax, the common clubtail, is a species of dragonfly in the family Gomphidae. It is found throughout the Indomalayan region.
Ictinogomphus australis, known as the Australian tiger, is a species of dragonfly in the family Lindeniidae, which was formerly part of the family Gomphidae. It is found near rivers, lagoons, lakes and ponds. They are large dragonflies with eyes widely spaced on top of the head. They have clear wings and are yellow and black in colour. The males are identified from females by two curved flaps below segment eight of the abdomen. They are found in an arc ranging from about Broome, Western Australia along the north of the continent to Point Hicks on the south-east corner. The taxon has been assessed for the IUCN Red List as being of least concern.
Ictinogomphus dobsoni is a species of dragonfly in the family Lindeniidae which was formerly part of the family Gomphidae, and known as the Pilbara tiger. It is a medium to large, black dragonfly with yellow markings and clear wings. Ictinogomphus dobsoni is endemic to the Pilbara region in Western Australia, where it inhabits rivers, lakes and ponds.
Ictinogomphus paulini is a species of dragonfly in the family Lindeniidae which was formerly part of the family Gomphidae, and known as the Cape York tiger. It is a medium to large, black dragonfly with yellow markings and clear wings. Ictinogomphus paulini is endemic to Cape York, Queensland, Australia, where it inhabits rivers.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
