Species which are endangered




















Geographically, their population is distributed throughout the North Atlantic, from Ecuador to Norway and from the Black Sea to Mexico. Center for Biological Diversity. Prized as a high-value dish at sushi restaurants, bluefin are being push toward extinction by decades of overfishing. The goal of wildlife conservation is to ensure the survival of these species, and to educate people on living sustainably with other species. Developing protective areas such as national parks, wildlife sanctuaries to protect the animals in their natural habitat.

The endangered and vulnerable species can be kept in captivity in places such as local sanctuaries and bred to increase their population. The cutting of forests should be strictly prohibited. In order to successfully embody ecotourism , businesses need to consider the following three measures: Sustainable Business Practices, Community Development, and Environmental Stewardship.

Habitat destruction is the main threat to 85 percent of all threatened and endangered species, according to the International Union for Conservation of Nature. You can help reduce this threat by planting native trees, restoring wetlands or cleaning up beaches in your area. These are simple but sufficient methods to practice in order to maintain or pace the extent of human influence on the natural world.

The practice of such will help to secure the conservation of the 10 most endangered animals and others that are critically endangered.

Currently, one of their main threats is habitat loss. Large areas of their home have been cleared to make space for agriculture, destroyed by cyclones or taken over by invasive trees. They are also at risk of predation from invasive species, including feral cats. Gharials are fish-eating crocodiles from India. They have long thin snouts with a large bump on the end which resembles a pot known as a Ghara, which is where they get their name.

They spend most of their time in freshwater rivers, only leaving the water to bask in the sun and lay eggs. Unfortunately, Gharial numbers have been in decline since the s and, sadly, this large crocodilian is now close to extinction. There are only around to left in the wild. Their decline is due to several issues, though all human-made. Habitat loss , pollution and entanglement in fishing nets pose some of the biggest threats, along with poachers that target them for use in traditional medicine.

Kakapos are nocturnal ground-dwelling parrots from New Zealand, and yet another example of an animal brought to the edge of extinction by humans. They are critically endangered with only around individuals remaining, each one with an individual name. They were once common throughout New Zealand and Polynesia but now inhabit just two small islands off the coast of southern New Zealand. One of the main threats to Kakapos is predation from introduced species such as cats and stoats that hunt using scent.

It is effective against predators that rely on sight to hunt but not smell. Females also leave the nest unattended when finding food, leaving the eggs freely available to predators. Intensive conservation measures mean the population is on the increase now, which is positive. But, genetic diversity is low among the remaining kakapo, which could affect survival in the future, especially if they are struck by a disease. That number is now estimated to be less than Like all species on our endangered list, humans are their biggest threat.

Their beautiful coats are popular with poachers as are their bones which they sell for use in traditional Asian medicine. They are also at risk from habitat loss due primarily to natural and human-made fires. Climate change is also changing Amur leopard habitat and leading to a decrease in prey availability.

The vaquita is both the smallest and the most endangered marine mammal in the world. It has been classified as Critically Endangered by the IUCN since , and in , there were only around 6 to 22 vaquitas left. Development can also endanger species indirectly. Some species, such as fig trees of the rain forest, may provide habitat for other species.

As trees are destroyed, species that depend on that tree habitat may also become endangered. Tree crown s provide habitat in the canopy , or top layer, of a rainforest. Plants such as vines, fungi such as mushrooms, and insects such as butterflies live in the rain forest canopy. So do hundreds of species of tropical birds and mammals such as monkeys.

As trees are cut down, this habitat is lost. Species have less room to live and reproduce. Loss of habitat may happen as development takes place in a species range. Many animals have a range of hundreds of square kilometers. The mountain lion of North America, for instance, has a range of up to 1, square kilometers square miles.

To successfully live and reproduce, a single mountain lion patrol s this much territory. That means the habitat can support fewer mountain lions. Because enormous parts of the Sierra Nevada, Rocky, and Cascade mountain ranges remain undeveloped, however, mountain lions are not endangered. Loss of habitat can also lead to increased encounters between wild species and people. As development brings people deeper into a species range, they may have more exposure to wild species.

Poisonous plants and fungi may grow closer to homes and schools. Wild animals are also spotted more frequent ly. These animals are simply patrolling their range, but interaction with people can be deadly. Polar bears, mountain lions, and alligators are all predators brought into close contact with people as they lose their habitat to homes, farms, and businesses. As people kill these wild animals, through pesticide s, accidents such as collisions with cars, or hunting, native species may become endangered.

Loss of Genetic Variation Genetic variation is the diversity found within a species. Genetic variation allows species to adapt to changes in the environment. Usually, the greater the population of a species, the greater its genetic variation.

Inbreed ing is reproduction with close family members. Groups of species that have a tendency to inbreed usually have little genetic variation, because no new genetic information is introduced to the group.

Disease is much more common, and much more deadly, among inbred groups. Inbred species do not have the genetic variation to develop resistance to the disease. For this reason, fewer offspring of inbred groups survive to maturity. Loss of genetic variation can occur naturally. Cheetah s are a threatened species native to Africa and Asia.

These big cat s have very little genetic variation. Biologist s say that during the last ice age , cheetahs went through a long period of inbreeding. As a result, there are very few genetic differences between cheetahs. They cannot adapt to changes in the environment as quickly as other animals, and fewer cheetahs survive to maturity. Cheetahs are also much more difficult to breed in captivity than other big cats, such as lions.

Human activity can also lead to a loss of genetic variation. Overhunt ing and overfish ing have reduced the populations of many animals. Reduced population means there are fewer breeding pairs.

A breeding pair is made up of two mature members of the species that are not closely related and can produce healthy offspring. With fewer breeding pairs, genetic variation shrinks. Monoculture , the agricultural method of growing a single crop , can also reduce genetic variation. Modern agribusiness relies on monocultures. Almost all potatoes cultivate d, sold, and consumed, for instance, are from a single species, the Russet Burbank. Potatoes, native to the Andes Mountains of South America, have dozens of natural varieties.

The genetic variation of wild potatoes allows them to adapt to climate change and disease. For Russet Burbanks, however, farmers must use fertilizer s and pesticides to ensure healthy crops because the plant has almost no genetic variation.

Plant breeders often go back to wild varieties to collect genes that will help cultivated plants resist pests and drought, and adapt to climate change. However, climate change is also threatening wild varieties. That means domesticated plants may lose an important source of traits that help them overcome new threats.

The Red List has seven levels of conservation: least concern, near threatened, vulnerable, endangered, critically endangered, extinct in the wild, and extinct. Each category represents a different threat level. Species that are not threatened by extinction are placed within the first two categories—least concern and near-threatened. Those that are most threatened are placed within the next three categories, known as the threatened categories —vulnerable, endangered, and critically endangered.

Those species that are extinct in some form are placed within the last two categories—extinct in the wild and extinct. Classifying a species as endangered has to do with its range and habitat, as well as its actual population. For this reason, a species can be of least concern in one area and endangered in another. The gray whale, for instance, has a healthy population in the eastern Pacific Ocean, along the coast of North and South America.

The population in the western Pacific, however, is critically endangered. Least Concern Least concern is the lowest level of conservation. A species of least concern is one that has a widespread and abundant population. Human beings are a species of least concern, along with most domestic animal s, such as dogs and cats. Many wild animals, such as pigeons and houseflies, are also classified as least concern.

Near Threatened A near threatened species is one that is likely to qualify for a threatened category in the near future. Many species of violet s, native to tropical jungle s in South America and Africa, are near threatened, for instance. They have healthy populations, but their rain forest habitat is disappearing at a fast pace. People are cutting down huge areas of rain forest for development and timber.

Many violet species are likely to become threatened. Vulnerable Species The definitions of the three threatened categories vulnerable, endangered, and critically endangered are based on five criteria: population reduction rate, geographic range, population size, population restrictions, and probability of extinction. Threatened categories have different threshold s for these criteria.

As the population and range of the species decreases, the species becomes more threatened. This decline is measured over 10 years or three generations of the species, whichever is longer. A generation is the period of time between the birth of an animal and the time it is able to reproduce. Mice are able to reproduce when they are about one month old. Mouse populations are mostly tracked over year periods. An elephant's generation lasts about 15 years. So, elephant populations are measured over year periods.

A species is vulnerable if its population has declined at least 50 percent and the cause of the decline is known. Habitat loss is the leading known cause of population decline. A species is also classified as vulnerable if its population has declined at least 30 percent and the cause of the decline is not known.

A new, unknown virus, for example, could kill hundreds or even thousands of individuals before being identified. An area of occupancy is where a specific population of that species resides. This area is often a breeding or nesting site in a species range.

The species is also vulnerable if that population declines by at least 10 percent within 10 years or three generations, whichever is longer. A species is vulnerable if it is restricted to less than 1, mature individuals or an area of occupancy of less than 20 square kilometers 8 square miles.

These formulas calculate the chances a species can survive, without human protection, in the wild. Vulnerable Species: Ethiopian Banana Frog The Ethiopian banana frog Afrixalus enseticola is a small frog native to high- altitude areas of southern Ethiopia.
