There are at least 2109 species of dicotyledons found in Montana according to the Montana Field Guide. This is a list of Dicotyledoneae orders found in Montana. The Montana Natural Heritage Program has identified a number of dicot species as "Species of Concern"."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." Some of these species are exotics (not native to Montana).Exotic species have been deliberately or accidentally introduced to areas outside of their native geographic range and are able to reproduce and maintain sustainable populations in these areas. These exotic populations may also be referred to as alien, introduced, invasive, non-native, or non-indigenous.
