Huge chunk of plants, animals in U.S. at risk of extinction -report By Reuters

(Reuters) -A leading conservation research group found that 40% of animals and 34% of plants in the United States are at risk of extinction, while 41% of ecosystems are facing collapse.

Everything from crayfish and cacti to freshwater mussels and iconic American species such as the Venus flytrap are in danger of disappearing, a report released on Monday found.

NatureServe, which analyzes data from its network of over 1,000 scientists across the United States and Canada, said the report was its most comprehensive yet, synthesizing five decades’ worth of its own information on the health of animals, plants and ecosystems.

Importantly, the report pinpoints the areas in the United States where land is unprotected and where animals and plants are facing the most threats.

Sean O’Brien, president of NatureServe, said the conclusions of the report were “terrifying” and he hoped it would help lawmakers understand the urgency of passing protections, such as the Recovering America’s Wildlife Act that stalled out in Congress last year.

“If we want to maintain the panoply of biodiversity that we currently enjoy, we need to target the places where the biodiversity is most threatened,” O’Brien said. “This report allows us to do that.”

U.S. Representative Don Beyer, a Democrat who has proposed legislation to create a wildlife corridor system to rebuild threatened populations of fish, wildlife and plants, said NatureServe’s work would be critical to helping agencies identify what areas to prioritize and where to establish migration routes.

“The data reported by NatureServe is grim, a harrowing sign of the very real problems our wildlife and ecosystems are facing,” Beyer told Reuters. “I am thankful for their efforts, which will give a boost to efforts to protect biodiversity.”

HUMAN ENCROACHMENT

Among the species at risk of disappearing are icons like the carnivorous Venus flytrap, which is only found in the wild in a few counties of North and South Carolina.

Nearly half of all cacti species are at risk of extinction, while 200 species of trees, including a maple-leaf oak found in Arkansas, are also at risk of disappearing. Among ecosystems, America’s expansive temperate and boreal grasslands are among the most imperiled, with over half of 78 grassland…
