Species biodiversity and wildlife population numbers have been declining in Canada for decades. According to the most recent Living Planet Report Canada, species that are deemed at-risk of extinction have experienced an average population decline of 59% compared to 1970. [23]
The wildlife of Canada or biodiversity of Canada consist of over 80,000 classified species, [a] and an equal number thought yet to be recognized. [3] Known fauna and flora have been identified from five kingdoms: [ 4 ] protozoa represent approximately 1% of recorded species; chromist (approximately 4); fungis (approximately 16%); plants ...

The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
The 2024 Living Planet Report details "a catastrophic 73% decline in the average wildlife populations over just 50 years." ... the number of winter-run Chinook salmon dropped 88% since 1970. The ...
The Atlantic fishery abruptly collapsed in 1993, following overfishing since the late-1950s, and an earlier partial collapse in the 1970s. [1] It is expected to recover to historical, sustainable levels by 2030. [2] In 1992, Northern Cod populations fell to 1% of historical levels, due in large part to decades of overfishing. [3]
The 2018 report found a "decline of 60% in population sizes" of vertebrate species overall from 1970 to 2014. The tropics of South and Central America had an 89% loss compared to 1970. [ 2 ] These claims have been criticized by some studies such as the research group led by Brian Leung and including Maria Dornelas .
As wood bison species became threatened with the hybridization, relocation and breeding conservation programs specific to wood bison were established in 1963. The population increased steadily. From the 1970s to the 1990s, however, the population began to decline again because of the spread of bovine tuberculosis. The disease had accompanied ...
