    Multiple stable states of tree cover in a global land surface model due to a fire‐vegetation feedback by G. Lasslop, V. Brovkin, C. H. Reick, S. Bathiany, S. Kloster

    Published 2016-06-01
    “…The multiple stable states occur in the transition zones between grasslands and forests, mainly in Africa and Asia. By sensitivity simulations and simplifying the relevant model equations we show that the occurrence of multiple states is caused by the sensitivity of the fire disturbance rate to the presence of woody plant types.…”
