In the past centuries, farmland has undergone a fundamental transformation through changed farming practices, such as the use of agrochemicals and advanced machine processing. Particularly since the 1970s, agriculturally driven land-use change has caused destruction of natural and semi-natural habitats, and as a consequence, severe loss of biodiver...

Red Lists are important tools for nature conservation, especially if up-to-date information on the threat status of species is available. Due to the high diversity of habitats (e.g., elevation and climatic zones) within a small area, Austria’s wild bee diversity is high compared to other Central European countries, with currently 702 species listed...
