Effective national and international laws are needed to reverse the decline of populations of large carnivores—such as tigers, wolves, and eagles—and reduce their risk of extinction, reports a paper published in Scientific Reports. The authors find that of 362 carnivore species assessed, only 12 species (mostly marine mammals) have shown genuine improvement in extinction risk. Carnivores protected by international legislation were 6.8 times as likely to show a reduced extinction risk, while those with controlled hunting plans were three times as likely to be at lower risk of extinction.
