Protected Areas (PAs) are a main conservation tool to halt biodiversity loss. However, their performance has been often questioned and the need to improve their effectiveness is now more apparent than ever. Here, we propose Roadless Areas as a conservation target to increase the cover and effectiveness of PAs. Roadless Areas represent natural and semi-natural areas of high conservation value th...
