The major factors affecting Virgin spinedace are water diversion, impoundment, channelization, degradation of water quality, and introduced species, both fishes and crayfish. Two specific problems are competition with "Richardsonius hydrophlox" and predation by brown trout ("S. trutta"). Management emphasizes implementation of the Virgin River Spinedace Conservation Agreement, which calls for the protection and enhancement of the Virgin River water quantity and quality as well as seeks to limit the effects of nonnative fish species in Spinedace waters, and also aims

The White River spinedace ("Lepidomeda albivallis") is a critically endangered cyprinid fish of Nevada, occurring only in the White River in the southeastern part of the state. This spindace ranges from green to olive above, a brassy silver on the sides, becoming a silvery white underneath. The sides may also have a pattern of faint sooty patches. Dorsal and caudal fins are shades of brown, ranging from olive brown to a pinkish brown; the rays tend to be olive with the membranes between being transparent with a rosy

Virgin spinedace


The Virgin spinedace or Virgin River spinedace, "Lepidomeda mollispinus", is a cyprinid fish of the Virgin River, a tributary of the Colorado River in the United States. This spinedace is overall silvery in color, with a brassy sheen and a pattern of sooty blotches or speckles on each side. The dorsal fin has eight rays, the first two of which are spiny, the second being longer than the one closer to the frontal area. The anal fin has eight to 10 rays, usually 9. The breeding male

Astatotilapia bloyeti


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

. It grows along the banks of rivers and wetlands in alpine areas, preferring sand, pebbly or bolder-rich alluvial substrates. Outside these areas it does descend into lowland areas, occurring along main rivers such as the Visla and the Rhine (often with Salix eleagnos and Myricaria germanica) as well as in loose sand dunes. The species is regarded by the IUCN as having a conservation status of 'Least Concern' because of its broad distribution, especially within a number of ecologically protected areas. Nevertheless, it is listed

Western black rhinoceros


concluded that the rhino was extinct approximately five years before it was officially declared so by the IUCN. There were many attempts to revive Western Black and Northern White. Rhino sperm was conserved in order to artificially fertilize females to produce offspring. Some attempts were successful, but most experiments failed due to different reasons, including stress and reduced time in the wild. In 1999, WWF published a report called "African Rhino: Status Survey and Conservation Action Plan." This report recommended that all surviving specimens of the Western Black Rhino

According to the global authority on nature conservation, International Union for the Conservation of Nature (IUCN), the sea turtles of the Hawaiian Islands were also once under the threat of near extinction, but are now thriving and their conservation status reclassified as "Least Concern" according to the IUCN Red List. Thus, Yeh established Sea Turtles 911 under Hawaiian jurisdiction, and changed the course of his life by moving to China to save the sea turtles he had hopelessly witnessed being sold, earning

Narrow-ridged finless porpoise


Chinese government has given this species the utmost conservation status of "National First Grade Key Protected Wild Animal" to ensure its survival. Global conservation agencies and charities, such as the World Wildlife Fund and IUCN, have been collaborating with the Chinese government to ensure the survival of the species. There are two subspecies of narrow-ridged finless porpoise, the Yangtze and the East Asian finless porpoises, the former inhabiting the Yangtze River, and the latter the coastal areas off mainland China (e.g. Chongming Island), the Penghu Islands

Fitzroy River turtle


Anecdotal records since indicate up to 5 clutches may occur. Their habitat comprises a total area of less than 10,000 km², including the Fitzroy, Mackenzie and Dawson rivers. Its limited distribution and status as sole survivor of a once more widespread genus give it a high priority for conservation. The species has been listed as vulnerable on the IUCN checklist since 1994. The Fitzroy River turtle is commonly known as the "bum breathing turtle". This nickname is derived from their unusual ability to absorb oxygen whilst submerged through highly vascularized bursae

In Bhutan, white bellied herons are found in the low elevation riparian habitat below 1700 m, particularly in the Punatsang Chhu (river) basin. About 30 individual birds are known within the river valley of

Plains rat


' by the International Union for the Conservation of Nature (IUCN), the IUCN conservation status for the species is 'vulnerable'. The name "Pseudomys" comes from the combined form of the Greek word "pseudes" (meaning "false") and the Latin word "mys" (meaning "mouse"), presumably because of the plains rat's puzzling similarities and differences to "true mice" in the genus "mus". The name "australis" comes from the Latin word "australis" (

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:
