Description: Das Projekt "Grassland restoration in Northern China from a whole plant perspective (GrassRest)" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Tropische Agrarwissenschaften (Hans-Ruthenberg-Institut) (490), Fachgebiet Wasserstreß-Management bei Kulturpflanzen in den Tropen und Subtropen (490g) durchgeführt. Restoration ecology became more and more important to cope with grassland degradation and to develop management options to improve grassland quality towards a sustainable livestock based land-use system. Overgrazing and climate change result in unpredictable effects on grassland productivity due to multiple feedbacks on resources availability. During the restoration process, the limited availability of resources often constrain plant establishment and growth, but most research approaches focus on aboveground plant productivity dynamics to assess restoration progress rather than following a whole plant perspective including the belowground part. In temperate steppe ecosystems plant carbon is predominantly located belowground and it is evident that resource allocation between shoot and root plays an important role in ecosystems resilience in response to multiple stresses. Plant species of steppe ecosystems are usually well adapted to water stress and harsh winter conditions of the continental climate by storing nutrients and carbohydrates in perennial belowground organs. A depletion of these belowground resources increases vulnerability of plants to stress periods and endangers the restoration process. The belowground response of grassland plants to multiple stresses thus can be a key process in grassland restoration and ecosystems adaptation capacity to climate variability or change. Therefore, assessing different restoration techniques from a whole plant perspective will contribute to optimize grassland management towards a sustainable land-use practice to assure farmers income from livestock based systems.
