Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity , an example being the military macaw . In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. [ 1 ]
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. As of September 2016, the International Union for Conservation of Nature (IUCN) lists 5430 Vulnerable (VU) plant species. [1] 25% of all evaluated plant species are listed as Vulnerable. The IUCN also lists 244 subspecies and 235 varieties as Vulnerable.
A threatened species is any species (including animals, plants and fungi) which is vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation , a mathematical measure of biomass related to population growth rate .
This course is designed to provide students with scientific principles, concepts, and methodologies necessary to comprehend the relationships abundant within the natural world, to identify and analyze environmental problems, to evaluate relative risks associated with these identified problems, and to examine alternative solutions for resolving and/or preventing similar problems facing the ...

The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

A facilitation cascade is a sequence of ecological interactions that occur when a species benefits a second species that in turn has a positive effect on a third species. [1] These facilitative interactions can take the form of amelioration of environmental stress and/or provision of refuge from predation .
