[Animals] More than a third of US wildlife at risk of extinction, 'grim' new report shows

[BirSaNN]

A report from the conservation group NatureServe warns that 40% of animals and 34% of plants in the U.S. are "at risk" of extinction.

A new report(opens in new tab) has painted a grim picture of the future for wildlife in the U.S.: Up to 40% of animal species and 34% of plant species are at risk of going extinct in the country, and up to 41% of U.S. ecosystems are at risk of range-wide collapse, meaning they could be lost forever.

NatureServe, a conservation group focused on biodiversity in North America, released the report Feb. 6. The report ranks all U.S. species on their risk of being wiped out. The categories include secure, apparently secure, vulnerable, imperiled, critically imperiled and possibly extinct; any species in the last four groups are considered to be "at risk of extinction." The rankings are based on more than 50 years of data collected by NatureServe, using a network of more than 1,000 scientists. 

"The data reported by NatureServe is grim," U.S. Rep. Don Beyer, D-Va., told Reuters(opens in new tab). It is "a harrowing sign of the very real problems our wildlife and ecosystems are facing." 

NatureServe President Sean O'Brien said the report's conclusions were "terrifying," but he hopes it will help lawmakers understand the urgency of passing new protections, Reuters reported.

The animals most at risk are snails, with 75% of freshwater snails and 74% of terrestrial snails at risk of extinction, followed by freshwater mussels (65% at risk), crayfish (55% at risk), shrimps (48% at risk) and bees (37% at risk). Freshwater species seem to be particularly vulnerable due to an increase in waterway pollution and damming activity, the report authors wrote.  

Among the broader major animal groups, amphibians are the worst off, with 42% at risk, followed by fish (35% at risk), reptiles (22% at risk), mammals (18% at risk) and birds (12% at risk). 

Some of the most notable animal species listed as critically imperiled include the red wolf (Canis rufus), the recently cloned black-footed ferret (Mustela nigripes), the Mississippi gopher frog (Lithobates sevosus), the highly inbred Devils Hole pupfish (Cyprinodon diabolis), Kemp's Ridley sea turtle (Lepidochelys kempii), the North Atlantic right whale (Eubalaena glacialis) and Rice's whale (Balaenoptera ricei), which was only discovered in 2021.

Among plants, cacti are the most threatened group, with 48% at risk, followed by orchids (27% at risk), trees (20% at risk) and grasses (19% at risk). Some notable at-risk plants include the Venus flytrap (Dionaea musci[CENSORED]), which is imperiled, and the maple leaf oak (Quercus acerifolia), which is critically imperiled. The scientists wrote that plants will be particularly vulnerable in the future because they do not receive the same level of conservation funding as animals do.
