Is the Canada lynx endangered?

No, the Canada lynx is not considered endangered. You may dispute this assessment by the IUCN Red List^TM. It is the experts who work on behalf of the Red List who make the classification. The Red List's purpose is to "determine the relative risk of extinction" of the world's species. They classify the Canada lynx as "Least Concern". This means it is considered to be "widespread and abundant". It is the lowest (softest) classification in terms of risk of extinction. Where do they get the population numbers from? Trappers? The Red List says that the population is stable. The assessment has not altered since 1996.
