6. sessions with adjustments in the scores in order to compare the differences of adjusting particular parameters Interpret Results The results from your WHIPPET session provide a provisional prioritization based on current objective data at hand This prioritization should next be reviewed by informed reviewers and collaborators who can inspect the rankings and the information they are based on The prioritization may be modified based on factors not included expressly in the model or the WHIPPE T session itself may be modified and run again with adjusted parameters For transparency and future understanding changes and their justification should be documented The overall priority score for a given population is as objective as possible and provides insight into why a given population was or was not a high priority for eradication Look at the major criteria scores Impact Invasiveness Feasibility for further insight The actual priority score is not as meaningful as its rank relative to the other targeted populations Some clustering of populations of the same species will occur because the species level criteria contribute considerable weight to the overall priority score Note If you are relying on Calflora records that are not your own widespread species may rank artificially high in the results This will happen because many widespread species such as annual grasses are underreported and therefore will show up as isolated populations when
