From Matthew Preston at C2C Journal:
For the first time in my 28-year life ruffed grouse are so numerous around the family farm in northeastern Alberta that I don’t have to trudge through the willows to find them. They regularly strut through the front yard, so common the dogs hardly notice. Up in Nunavut, meanwhile, there are so many polar bears that they “may have exceeded the co-existence threshold” and become a serious threat to humans in some communities, according to a recent Nunavut government report. These anecdotal observations are supported by the latest Wild Species survey of Canadian flora and fauna, which concluded that “the majority of species in Canada are secure. In fact…80 percent of species have a national rank of apparently secure or secure.” So when the World Wildlife Fund (WWF) and Zoological Society of London’s (ZSL) Living Planet Report 2018 was reported by the CBC to have concluded that “60 percent of world’s wildlife has been wiped out since 1970”, the stark contradiction of credible research as well as my own experience cried out for investigation. More.
Reality check: Organizations that depend on panic button funding are hardly useful for gathering reliable statistics, whether on humans or animals. It’s not well known that many species claimed to be extinct turn up again (“Lazarus species”). This is partly due to a tendency today to declare a species extinct too soon.
