Conservation Efforts Are Succeeding Overall at Slowing Biodiversity Loss, Global Study Confirms

A first-of-its-kind study that analyzed hundreds of conservation actions around the world has confirmed that efforts toward preserving wildlife are resulting in measurable achievements.

The international study, published in the journal Science, sought to assess whether conservation efforts were having any positive impacts on biodiversity. Researchers analyzed 186 studies, including 665 trials, and measured changes to biodiversity.

Overall, the researchers found that about two-thirds of the studied conservation actions at minimum slowed biodiversity declines or led to improved biodiversity. 

"If you read the headlines about extinction these days, it would be easy to get the impression that we are failing biodiversity — but that's not really looking at the whole picture," Penny Langhammer, co-author of the study and executive vice president of Re:wild, told the BBC. "This study provides the strongest evidence to date that not only does conservation improve the state of biodiversity and slow its decline, but when it works, it really works."
