More than 2,000 wild species face a high risk of being wiped out in Canada, report warns

A newly released report on the status of wild species in Canada has cataloged more species than any previous report тАФ over 50,000 тАФ and warns that more than 2,000 of them face a high risk of being wiped out in the wild.

The Wild Species 2020 report, compiled by researchers working for the federal,┬аprovincial and┬аterritorial┬аgovernments, says it has delivered “the most complete understanding we have ever had on the status and distribution of wild species in Canada.”

The report тАФ┬аthe fifth in a series published every five years since 2000 тАФ┬аincludes data on the status of 50,534 of Canada’s 80,000 known species, up from the 29,848 species covered in the 2015 report. The first report in 2000 covered just 1,670 species.

The authors of the report say they were able to┬аrecord information on 63 per cent of Canada’s wild species through the collaboration of hundreds of scientists working across the country for five years.┬а

Of the species contained in the report, 47,314 are indigenous to Canada, while 3,220 are┬а“exotic” species┬аintroduced through human activity.

“Among the 3,220 exotic species identified, the taxonomic groups with the highest number of exotic species were the vascular plants, beetles, true bugs, and moths and butterflies,” the report says.┬а

The report’s authors said that more work can be done to determine┬аthe impact these exotic species are having on ecosystems across the country.

At-risk species

The report covers┬аabout 63 per cent of wild species in Canada┬атАФ┬аabout 75 per cent of plants, 77 per cent of fungi and 29 per cent of microscopic wild species.

The three provinces with the most wild species are Ontario at 25,776, British Columbia at 24,540 and Quebec at 21,933.

The report identified 2,253 species facing the┬аhighest risk of elimination in Canada. They┬аinclude beetles, moths, butterflies and some plant species such as macrofungi and lichens.

The report says that of those 2,253 species,┬а105 are only found in Canada тАФ┬аmeaning that their survival as a species is in peril.

“The number of species that may be at risk identified in the Wild Species reports has continuously increased largely due to the increased number of species included,” the report said.

The report says that about one in five wild species in Canada face some risk of extirpation тАФ of elimination in this country.

The report said 873 species are critically imperiled тАФ are at high risk of being eliminated┬аin the wild тАФ another 1,245 fall under the slightly less severe category of imperiled, while 2,765 species are considered vulnerable,┬аat moderate risk of being wiped out in the wild.

The authors of the report said 9,562 species can be considered apparently secure, or at a fairly low risk of extirpation, while 10,038 species are considered secure or at a very low risk of extirpation.

The report said that of the species that were ranked to determine their status, 80 per cent were considered secure and 20 per cent faced some risk of being eliminated in the wild.┬а

The report said that another 26,000 species were unrankable┬аdue to insufficient data.
