REUTERS/Luisa GonzalezFeb 6 (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.
Importantly, the report pinpoints the areas in the United States where land is unprotected and where animals and plants are facing the most threats.
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.
The threats against plants, animals and ecosystems are varied, the report found, but include "habitat degradation and land conversion, invasive species, damming and polluting of rivers, and climate change."
California, Texas and the southeastern United States are where the highest percentages of plants, animals and ecosystems are at risk, the report found.
