Wiederansiedlung seltener und gefährdeter Ackerwildpflanzen auf Ökobetrieben. Teilprojekt Witzenhausen: Versuche auf Praxisbetrieben

Summary

Abundance and diversity of arable weeds have been strongly declining in many European regions. Arable weeds are highly dependent on the respective type of management, and thus future programs for conservation of rare arable weeds have to establish a close and innovative integration with sustainable farming practice. The project “Restoration of local populations of rare and endangered arable field plants on organic farms in Germany” aims at developing applied scientific knowledge on new methods for conservation of arable weeds within farming systems. Two complementary research teams in contrasting regions in Germany test different approaches to reestablish arable weeds under various management systems and with different preconditions. The research team of the University of Kassel investigates the transfer of remnant populations of the species from nearby populations to organic fields. Two methods are being tested: the transplantation via seeds and the transplantation via transfer of surface soil.
