An Atlas of Endangered Species

Product Information

A species is also classified as endangered when its population has declined at least 80 percent and the cause of the decline is not known. Classifying a species as endangered has to do with its range and habitat, as well as its actual population.

A species is also classified as endangered when its population has declined at least 50 percent and the cause of the decline is not known. A breeding pair is made up of two mature members of the species that are not closely related and can produce healthy offspring. Of the 19 species, the one I would really like to get to grips with in the wild is the wild camel of Mongolia/China. That’ll never happen as there are some political and practical reasons why it would be tricky, and this is one of those species where the people who know it best have hardly seen it. A species is also classified as vulnerable if its “ area of occupancy” is estimated to be less than 2,000 square kilometers (772 square miles).Groups of species that have a tendency to inbreed usually have little genetic variation, because no new genetic information is introduced to the group. Non-native plants crowded the cyanea out of its habitat, and non-native animals such as pigs, rats, and slugs ate its fruit more quickly than it could reproduce.

The Siberian sturgeon is an endangered species because its total population has declined between 50 and 80 percent during the past 60 years (three generations of sturgeon). With twenty percent of the earth's species facing extinction by 2030, this striking atlas brings up to date the data on those that have been lost already, those that are threatened, and those that are surviving today. The Convention on Biological Diversity is an international treaty to sustain and protect the diversity of life on Earth. In the midst of a biodiversity and climate crisis, there is a lot to discuss and it can feel overwhelming! Megan McCubbin's mini-anthology of animals at risk is full of striking tales, including ones about snow leopards and partying orcas.Galapagos kelp is classified as vulnerable because its population has declined more than 10 percent over 10 years.
