, the Rio del Presidio trout were the southernmost natural distribution of any member of the family Salmonidae. This range was extended by collections from the ríos Baluarte and Acaponeta in 2004. The many forms of Mexican native trout are typically described by the river systems they occur in. The Mexican golden trout ("O. chrysogaster") is listed as vulnerable by the IUCN Red List of Threatened Species.

golden trout ("Oncorhynchus chrysogaster") is a recognized species. Most of the Mexican native trout are considered subspecies of the rainbow trout ("O. mykiss") and generally lumped as "O. m. nelsoni" or "O. m. ssp". The exception is the Mexican golden trout ("O. chrysogaster" ) which achieved species status in 1964. The first records of trout in northwest Mexico were published by paleontologist E. D. Cope in 1886 where he describes two specimens from Chihuahua as having the appearance of "Salmo purpuratus

In 1989, morphological and genetic studies indicated trout of the Pacific basin were genetically closer to Pacific salmon ("Oncorhynchus" species) than to the "Salmos"–brown trout ("S. trutta") or Atlantic salmon ("S. salar") of the Atlantic basin. Thus, in 1989, taxonomic authorities moved the rainbow, cutthroat and other Pacific basin trout, including the Mexican golden trout into the genus "

biggest threats are human development and the possibility of competition/interbreeding with introduced rainbow trout. The scenic area and rugged mountainous landscape have started a budding tourism industry for this area. Being able to conserve and promote the sustainable harvesting of these native trout can help the people of the area as well as the Golden Trout. Setting up regulations on the harvesting of the fish and restrictions on polluting the head waters these fish inhabit would greatly improve the region.

In 2015, a report delving into the genetics of Mexican golden trout & Mexican rainbow trout from various rivers was published.

The species is endemic to high-elevation headwaters of the Fuerte River, Sinaloa River, and Culiacán River drainages in the Sierra Madre Occidental in Mexico. In 1936, Paul Needham, a fisheries biologist with the U.S. Bureau of Fisheries began a series of explorations (1936, 1937 and 1938) into the Rio Santo Domingo drainage in Baja California seeking to bring back live specimens of the Baja rainbow trout as hatchery stock and

However, its status in Mexico is poorly known; were it in a decline there, it might qualify for a category of higher risk. The decline is

Two public bodies in Britain, Natural England and the Joint Nature Conservation Committee (JNCC), have produced British Red Data Books and other reviews of different plants and animals assigning their conservation status according to IUCN Red Data Book criteria. In 2016 the JNCC produced a spreadsheet which incorporated these reviews and lists of threatened species based on other crieteria such as Biodiversity

Endangered species


protect conservation-reliant species: for example, forbidding hunting, restricting land development or creating protected areas. Population numbers, trends and species' conservation status can be found at the lists of organisms by population. The conservation status of a species indicates the likelihood that it will become extinct. Many factors are considered when assessing the status of a species; e.g., such statistics as the number remaining, the overall increase or decrease in the population over time, breeding success rates, or known threats. The IUCN Red List of

In the assessment of the inland "P. icterotis xanthogenys" for the federal government's "Action Plan for Australian Birds" 2000 it was assigned the status of 'near threatened'. The 2013 assessment by the International Union for Conservation of Nature (IUCN) on their IUCN redlist assigns a status of species of least concern. It notes the species has become less common and locally extinct and the population trend is declining due

Nepenthes mikei


undisclosed for conservation purposes, "N. mikei" grows alongside "N. flava". The conservation status of "N. mikei" is listed as Vulnerable on the IUCN Red List, based on an assessment carried out in 2000. This agrees with an informal assessment made by Charles Clarke in 2001, who also classified the species as Vulnerable based on the IUCN criteria. However, Clarke noted that since substantial populations of "N. mikei" lie within protected areas, they "are unlikely to become threatened in the foreseeable future".

Data deficient


A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance:

Astatotilapia bloyeti is a species of haplochromine cichlid from the coastal river systems of Tanzania. Reports from other areas of Africa are considered to refer to related species. The IUCN considers it to be endemic to the Pangani River and includes Kenya in its range. This species taxonomic status is uncertain and some authorities place it in the genus "Haplochromis" while others retain it in "Astatotilapia". This taxonomic uncertainty has led the IUCN to classify this species conservation status as Data Deficient. The specific name honours the collector of the type
