Asplenium dielfalcatum is a species of fern in the family Aspleniaceae. It is native to Oahu, Hawaii. [1]
This plant is found at elevations between 400 and 1,000 m (1,300 and 3,300 ft). [1]
It is listed as critically endangered by the IUCN. The species is threatened by invasive species and climate change. [1] It was listed as endangered by the United States Fish and Wildlife Service on October 29, 1991. [2]
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
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).
Asplenium scolopendrium, commonly known as the hart's-tongue fern, is an evergreen fern in the family Aspleniaceae native to the Northern Hemisphere.
Megalagrion is a genus of damselflies in the family Coenagrionidae. It contains approximately 26 species, all of which are endemic to Hawaiʻi. Megalagrion damselflies are the only native damselflies in Hawaiʻi, and are referred to as "pinapinao" in ʻ ʻŌlelo Hawaiʻi. Other endemic Hawaiian Odonata are the dragonflies Anax strenuus and Nesogonia blackburni, which are referred to as "pinao".
Amaranthus brownii was an annual herb in the family Amaranthaceae. The plant was found only on the small island of Nihoa in the Northwestern Hawaiian Islands, growing on rocky outcrops at altitudes of 120–215 m (394–705 ft). It was one of nine species of Amaranthus in the Hawaiian Islands, as well as the only endemic Hawaiian species of the genus. It is now considered extinct.
The Nihoa conehead katydid is a species of katydid which is endemic to the Hawaiian island of Nihoa. It is one of the ten species in the genus Banza, all of them native to Hawaii, although it is the sister species to the remaining nine, and may belong in a separate genus. It gets its food mostly from plant leaves, but because of the low population, it does not do significant damage. Unlike Main Islands' species, whose males leap on the females before mating, the Nihoa variants sing to them. It is listed as a vulnerable species on the IUCN Red List, and as a "species of concern" under the Endangered Species Act.
Spelaeorchestia koloana, the Kauaʻi cave amphipod or ʻuku noho ana in Hawaiian, is a cave-dwelling crustacean only found on the Hawaiian island of Kauaʻi. It is eyeless and measures 7–10 mm (0.28–0.39 in) long. It is only known from 10 populations, and eats decaying plant matter and other decomposing material.
The Gulf Coast jaguarundi is an endangered population of the jaguarundi once ranging from southern Texas in the United States to eastern Mexico. The cat prefers dense shrubland and woodland, yet has been hampered by habitat loss.
The Jemez Mountains salamander is a species of salamander in the family Plethodontidae endemic to New Mexico in the United States. Its natural habitat is temperate forests. It is threatened by habitat loss, is in rapid decline, and was placed on the IUCN Red List in 2013.
Amastra spirizona is a species of land snail, a terrestrial pulmonate gastropod mollusk in the Amastridae family.
The Maui ʻakepa is a species of ʻakepa native to Maui in the Hawaiian Islands, and which was common throughout the island. Introduced mosquitoes and other animals to Maui contributed to the declining population, and the bird is considered Critically Endangered by the IUCN Red List of Threatened Species. The latest reported sighting of this bird was in 1988, and in 2021 the United States Fish and Wildlife Service proposed declaring it extinct. The species was delisted from the Endangered Species Act on October 16, 2023 citing extinction.
The Kauaʻi nukupuʻu was a species of nukupuʻu once found throughout parts of the Hawaiian island of Kauaʻi. It was an insect eater that picked out its tiny prey from tree bark. The males were yellowish with brown wings, while the females were grayish brown with a yellow throat streak.
Asplenium ceterach, also known as the rustyback fern, is a fern species in the spleenwort family Aspleniaceae.
Cyanea procera is a rare species of flowering plant in the bellflower family known by the common name Molokai cyanea. It is endemic to Hawaii, where it is known only from the island of Molokaʻi. It is a federally listed endangered species of the United States. Like other Cyanea it is known as haha in Hawaiian.
Tabernaemontana pandacaqui, known as windmill bush and banana bush, is a species of plant in the dogbane family Apocynaceae.
Asplenium dielerectum is a fern, a member of the spleenwort family. It is critically endangered.
Shuanglianpi Wetland is a partially protected natural area in Yilan County in northern Taiwan. Situated 470 meters above sea-level, it contains a botanically rich, shallow lake, which, from the perspective of plant species density, is considered to be a wetland with global significance by the Forestry Bureau of Taiwan.
