A new study by BirdLife International scientists, published in the journal Science, has shown that conservation actions are effective in stopping and even reversing biodiversity loss. The research examined conservation efforts globally, from the islands of Florida to the forests of the Amazon and Congo basin, as well as the rivers of the Asian plateaus.
Rather than focusing solely on individual conservation projects, the study encompassed a meta-analysis of 186 studies and 665 trials. This made it the largest study of its kind in terms of scale and time frame. It evaluated a wide range of conservation interventions around the world over more than a century.
The results showed that conservation actions have led to improvements in biodiversity or at least slowed its decline in a majority (66%) of cases compared to no action being taken. The study also revealed that when conservation interventions are successful, they are highly effective. These interventions included measures such as establishing and managing protected areas, eradicating and controlling invasive species, sustainably managing ecosystems, and reducing and restoring habitat loss.
