Researchers from the Technische Universitaet Muenchen and other
institutions are studying the development of a fledgling ecosystem at a
site called Huehnerwasser or "Chicken Creek." In a former open‑pit coal
mining area of Brandenburg, Germany, scientists partitioned off a surface
of six hectares and left nature to its own resources. They are closely
observing soil, flora, and fauna to determine what factors have a
particularly strong influence on developing ecosystems.
