Relationship between fire year and antecedent precipitation conditions for two elevation groups, (A) <2400 m (n = 12) and (B) >2400 m (n = 27), from 12 fire history studies on ponderosa pine (Pinus ponderosa) ecosystems in Colorado, USA, used in the fire regime meta-analysis of 2017. Y-axis represents the percent of all observations in each of three precipitation conditions: average precipitation, dry (below average), and wet (above average). Precipitation condition is derived from a combination of climate indices including Palmer Drought Severity, tree-ring growth, NINO3 sea surface temperature, and others. X-axis represents the year relative to fire year (y−0 is fire year, y−1 is year before fire year, and so on)
