National parks and other protected areas have had mixed success in conserving wildlife, according to the largest ever global study of their effects.
Using wetland bird data from 1,506 protected areas around the world, scientists analysed the trends of more than 27,000 populations, and found that increased provision for the birds had not necessarily helped.
Researchers said the study, published today in the journal Nature, has important implications for the movement to protect 30% of the Earth for wildlife by the end of the decade. The results show that managing parks to protect species and their habitats is crucial, and that without such management parks are more likely to be ineffective.
