From: Short-interval fires increasing in the Alaskan boreal forest as fire self-regulation decays across forest types

Figure 3

Proportion of fires observed in a given short interval and expected proportion in the absence of any spatial interaction/negative feedback (null model). (A) 10 year or less interval, showing general lack of increase in observed short-interval events despite increasing fires. (B) 20 year or less interval, where reburns are increasing at a similar rate to overall fires (suggesting a lack of negative feedbacks), but are lower, likely because the 0–20 year span integrates the < 10-year feedbacks in (A). (C) Isolating only 10–20 year intervals to show congruence between data points. Bars shown are the 25th/75th quantiles from the null model.
