A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
noun. Any species that is likely to become endangered within the foreseeable future. Supplement. A vulnerable species is one in which the species is susceptible to endangerment. The species is likely to become endangered when the population of that species declines.
An endangered species is a type of organism that is threatened by extinction. Species become endangered for two main reasons: loss of habitat and loss of genetic variation.
A Vulnerable (VU) species faces a high risk of extinction. One of the metrics that categorizes a vulnerable species is if quantitative analysis shows that there is a greater than 10% chance that it goes extinct in the wild within 100 years.
Vulnerable (VU), a category containing those species that possess a very high risk of extinction as a result of rapid population declines of 30 to more than 50 percent over the previous 10 years (or three generations), a current population size of fewer than 1,000 individuals, or other factors.
They look at what threats the species faces, too, and any actions underway to protect it. While all these categories are important in evaluating life on Earth, the term ‘endangered’ refers specifically to species listed as Critically Endangered, Endangered, and Vulnerable. Here’s how that boils down:
Endangered species, any species that is at risk of extinction because of a sudden rapid decrease in its population or a loss of its critical habitat. Previously, any species of plant or animal that was threatened with extinction could be called an endangered species.
Vulnerable species are those that are at a higher risk of extinction in the wild due to factors such as habitat loss, overexploitation, and climate change. These species often have a declining population trend and face threats that significantly reduce their ability to survive and reproduce.
The IUCN Red List of Threatened Species™ is the world’s most comprehensive information source on the global extinction risk status of animal, fungus and plant species. Open to all, it is used by governmental bodies, non-profit organisations, businesses and individuals.
Definition. In ecological terms, 'vulnerable' refers to species that are at risk of becoming endangered or extinct due to various threats. These threats can include habitat loss, climate change, pollution, and overexploitation, making these species more susceptible to population decline.
