The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category representing a different level of global extinction risk. Species that are considered to be "critically endangered" are placed within the "threatened" category

Population size reduction

The rate of reduction is measured either over a 10 year span or across three different generations within that species.

The cause for this decline must also be known.

Reduction across a geographic range

This reduction must occur over less than 100 km2 of geographic range OR the area of occupancy is less than 10 km2.

Declining population

The population must decline to less than 250 MI and either.

Population size reduction

The population size must be reduced to numbers of less than 50 MI.

Probability of extinction

There must be at least a 50% probability of going extinct in the wild within a 10 year span or across 3 generations.

Causes

The current extinction crisis is witnessing extinction rates that are occurring at a faster rate than that of the natural extinction rate. It has largely been credited towards human impacts on climate change and the loss of biodiversity. This is along with natural forces that may create stress on the species or cause an animal population to become extinct. The main causes for critically endangered species is the following.


 * 1) Loss of Habitat
 * 2) This is considered to be one of the most significant reasons animals and plants become endangered.
 * 3) Species rely on their habitat for the resources needed for their survival. If the habitat becomes destroyed, the population will see a decline in their numbers.
 * 4) Some activities that cause habitat loss is:
 * 5) Climate change
 * 6) Geologic change
 * 7) Human migration
 * 8) Highway construction
 * 9) Urbanization
 * 10) Agriculture
 * 11) Introduction of Invasive Species
 * 12) Invasive species invade and exploit a new habitat for its natural resources as a method to outcompete the native organisms.Eventually taking over the habitat.
 * 13) This can lead to either the native species' extinction or causing them to become endangered.
 * 14) Disease
 * 15) The introduction of a disease into a new habitat can cause it to spread amongst the native species.
 * 16) Due to their lack of familiarity with the disease or little resistance, the native species can die off.
 * 17) This will cause the population's numbers to be reduced.
 * 18) Environmental Population
 * 19) Pollution is harmful to both the species and habitat.
 * 20) This can cause the population's numbers to be reduced.
 * 21) Pollution can be in the form of:
 * 22) Air
 * 23) Light
 * 24) Noise
 * 25) Pesticides
 * 26) Chemicals
 * 27) Depletion of Natural Resources
 * 28) If resources become overexploited and depleted, there is no longer enough resources to sustain the native species of this habitat.
 * 29) Hunting/Fishing
 * 30) Overhunting of a certain species can cause other species whose

Conservation

A high percentage of species have become extinction and are considered to be critically angered. Conservation methods are necessary in order to provide relief and recovery for species that are facing extinction. This is due to the declining rate of biodiversity as ecosystems collapse alongside its extinct and critically endangered species. It would take years before another species population would return to the habitat and increase its biodiversity rate. Conservation methods such as the following allow for human imposed threats of these critically endangered species to be lessened.


 * 1) Educate Yourself and Others
 * 2) This is considered to be one of the most essential conservation methods.
 * 3) By learning about wildlife, you are better able to understand the importance of these endangered species and the resources needed for their survival.
 * 4) You can then educate friends, family, and neighbors on information regarding various local and global species.
 * 5) This includes activities such as:
 * 6) Visiting a national wildlife refuge or park
 * 7) Volunteering
 * 8) Observe the plants and animals around you
 * 9) Do Not Engage in Illegal Wildlife Captivity
 * 10) Poaching not only decreases the population's numbers, but also disrupts the balance of a certain habitat. This is due to the fact the certain species are considered to be assets to their environment as they provide it with natural resources. By poaching off a particular species, you may be depriving the habitat of the resources needed to sustain its other native animal and plant species.
 * 11) Poached animals have also been known to introduce and spread disease amongst human populations through wildlife trade. This can also affect the health of an environment by threatening its native species populations.
 * 12) Example: SARS, COVID-19, Ebola, etc.
 * 13) Develop Protective and Relief Projects for Threatened Species
 * 14) The Endangered Species Act was signed into law in 1973 by Richard Nixon in order to protect animals and plants who were facing possible extinction after an already visible decline of several species in the 1900s.
 * 15) This is intended to allow species to recover to the point where they no longer need protection.
 * 16) The U.S. Fish and Wildlife Service created the relief program "Critically Endangered Animals Conservation Fund" to send funding to continents such as Africa, Asia, South America, and Oceania to create projects that provide assistance with the recovery of critically endangered species from the brink of extinction.
