The most ambitious conservation policies will not be able to halt the decline of birds and butterflies in Europe. This is the conclusion of a study published in the journal 'Nature Ecology & Evolution', which analyzed the effectiveness of environmental protection measures to reverse the loss of biodiversity on the European continent.
According to the article, although it is essential to expand protected areas, restore ecosystems and promote sustainable agricultural and forestry practices, the decline of many species of birds and butterflies will not be easily reversed. These two groups of animals are considered key indicators of the state of ecosystems.
The study was led by two French research centers: INRAE and CESAB. Spanish institutions also participated in the research, namely CREAF, CSIC, the Catalan Ornithological Institute (ICO) and the Museu de Ciències Naturals de Granollers.
