Species of concern are native taxa that are at-risk due to declining population trends, threats to their habitats, restricted distribution, and/or other factors. Designation as a Montana species of concern or potential species of concern is based on the Montana Status Rank, and is not a statutory or regulatory classification. Rather, these designations provide information that helps resource managers make proactive decisions regarding species conservation and data collection priorities. See the latest species of concern reports for more detailed explanations and assessment criteria."Montana Field Guide-Species of Concern". Retrieved 2010-12-07.
