a geographic distribution and b temporal accumulation of 962 first reports of tree EIDs since 2000 for 24 tree genera. Note the scale in (a) has been log10 transformed and no reports of EIDs were found for countries coloured grey. Models in (b) were fitted as y ~ a × exp(b × x) + c, where y is the cumulative number of new reports and x is the number of years elapsed since 2000 (the first year of data collection). To facilitate interpretation and visualisation, x was back-transformed to year (by adding 2000). Native and non-native reports in (b) do not always sum to the total, as numerous host species had ambiguous geographic origins.
