We have developed a scorecard template to help us rate, for a given species, its impacts and our ability to respond to the species. We have drafted scorecards for over 200 species. Please select review next to the species you know, and use the comment form on the scorecard to let us know what scores we should consider changing. If you don't see a scorecard here for a species that you think should have a scorecard drafted, please choose Review Species List and use the comment form there. For a tabular presentation of scorecard values for multiple species, choose View Scorecard Summary.
