Short summary
Remote sensing studies indicate that tropical forest and savanna can be alternative stable states maintained by a feedback between tree cover and fire. Veenendaal et al. (2015) attempted to refute this hypothesis with an extensive field study of the vegetation structure and soil conditions at forest–savanna transition zones. With a re-analysis of their data and a conceptual model, we show that in fact the results agree with the idea of forest–savanna bistability.
