Fire return intervals in mixed grassland-fynbos vegetation in the Suurberg mountain range. Return intervals were measured as the number of years between each successive fire for each polygon of unique fire history. The data depicted here are from polygons of unique fire history that burnt twice or more over 21 years, i.e., polygons that burnt only once were excluded as return intervals could not be measured in them, while, for example, a polygon with three fires would have two return intervals
