A19 will address the phenomenon that succession of restored streams may not progress beyond early and mid-stages of community re-assembly. It will use mathematical models of stream com-munities and food webs to test, which ecological mechanisms differentially govern the alternative degradation and reassembly trajectories that lead either to full recovery or to the system getting locked in a depauperate state with limited levels of function.
