Conservationists have identified a number of animals as Indicator Species, meaning that the health and viability of their populations in the wild are believed to reflect the health of the entire ecosystem they inhabit.
Sustainability of one species allows other species to thrive. And this in turn affects the viability of tropical forests, fauna and the very environment that we live in. Conversely, the destruction of one species can unleash a chain reaction.
There are literally thousands of endangered species and it would be impractical to list them all here, however the following are considered to be amongst the most important indicator species.
A full list can be found in the IUCN Red Book, a comprehensive list of the world’s threatened species that is regularly updated. Visit www.iucnredlist.org.
