The article provides information about the BIODEPTH project, a project that tested plant species biodiversity and ecosystem properties in test plots at eight grassland sites around Europe. This generated a vast amount of data, and Andy Hector, who worked on the project, has figured out a way to pull it all together. BIODEPTH tested how different numbers of plant species affect ecosystem functions, such as total hay production or how well the ecosystem retains certain nutrients.
