Lineage AIS (shipping) data were used as baseline data. Vessels were grouped by category and the risk of diffusion of non native species due to biofouling was assessed using as criteria the probability of diffusion and the frequency of activity. The risk score was also multiplied by a "diversity" factor, which is the number of different vesseles occurring in the same area. A kernel density analysis was performed (using a 5km radius) across the EEZ zone of the Falklands. However the analysis of the risk of diffusion was focussed on the 12 nautical miles and the data are clipped to these boundaries. Tourism data from IAATO and anchorage points were also icluded in the analyses as the risk of introducing non native species from transferring tourists from the cruiseliner to the land was considered a relevant factor. The final risk map is made by adding the single risk maps for each vessel type and then the final risk value normalised on a scale o to 1.
