Scientists and the Provincial and Federal Governments use terms such as Special Concern, Threatened, Endangered, Extirpated and Extinct to describe the category that best fits the condition of each species and their numbers in our province and country.
How many lists are in IUCN?
nine Red List Categories
The IUCN Red List Categories indicate how close a species is to becoming extinct. The nine Red List Categories are shown below: Species are assessed against five criteria (see below) based on geographic range, population size and population decline/increase, in addition to extinction probability analyses.
What is the IUCN Green List?
The IUCN Green List is a global programme of certification aiming to achieve and promote effective, equitable, and successful protected and conserved areas by highlighting best practices, and providing a benchmark for progress towards effective and equitable management.

What are the 4 components of biodiversity?
Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other.
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem.
- Ecosystem Diversity.
- Functional Diversity.
Why are the 3 levels of biodiversity important?
Levels of biodiversity. Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversityecosystem diversityAn example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity.https://en.wikipedia.org › wiki › Ecosystem_diversityEcosystem diversity – Wikipedia. These three levels work together to create the complexity of life on Earth.
