A cute alternate of our four host tree sites' outbreak histories (and one regional -- 'OHD' -- record at the bottom). Outbreaks are simply represented as points rather than time series data showing percent infestations. Only moderate (40%) conditions are represented. Shaded region shows shared regional outbreak record. This was not used in my research, but was a fun way to learn how to customize graphics using R's ggplot2 package.
