LandscapeDNDC is a simulation framework for terrestrial ecosystem models on site and regional scales (Haas et al. 2013). LandscapeDNDC emerged from the site scale model MoBiLE (Grote et al. 2009b), which was based on the Arable-DNDC and Forest-DNDC models (Li et al. 1992a, b, 1994, 2000; Stange et al. 2000). The modular design of LandscapeDNDC allows plugging in any choice of process descriptions for various parts of different natural ecosystems.
