Rare Species Search Engine: Find Arkansas Species of Conservation Interest
You may select multiple items in the search boxes below. If no county is selected, the entire state (all counties) will be reported by default.
The species name may be entered as either the common name (Indiana bat) or the scientific name (Myotis sodalis). A general name ("bat") can also be entered but may bring up additional, unwanted listings containing the letters "b", "a", and "t".
Nomenclature of species is not contained in any single source. The most recent taxonomic sources are examined by our staff, and, when necessary, direct consultations with experts are used to maintain the most scientifically accepted names for all species. Divergences from these opinions are rare and generally occur while an ongoing taxonomic study is being conducted. Please contact our research staff if you have any questions or comments regarding the scientific names used here.
Standard common names have been developed and universally adopted for only a few species, therefore, more accurate results will be found using scientific names when possible. Many invertebrate species lack any common name at all and are indicated as "a caddisfly" or "a millipede", etc.
Once you have decided how you want to search in the database and have selected your parameters, you are ready to generate a report. When you click any of the "search by..." buttons, a new window will open that will display the information requested. The individual scientific names are listed in blue. Click on this name to be taken to the "Online Encyclopedia of Life" maintained by the international conservation data center NatureServe.
Species Rank and Status
Global ranks are assigned through NatureServe, a non-profit organization with a mission to provide the scientific basis for effective conservation action. NatureServe utilizes its international network of conservation professionals to make global rank assignments. These ranks address the range-wide rarity of a species using a scale of 1-5 (G1 = extremely rare and G5 = globally secure). Additional ranks are used to identify species considered extinct or of historical occurrence. The ranks may also have qualifiers to address subspecies, taxonomic issues, and breeding/non-breeding status.
State ranks are assigned by NatureServe’s “heritage program” partner in each state. The Arkansas Natural Heritage Commission (ANHC) serves as the state “heritage program” for Arkansas. Ranks are assigned using NatureServe’s rank calculator tool. Assigned ranks are typically reviewed by a committee of state professionals knowledgeable about the group. The review committee may make rank adjustments based on professional knowledge and experience. State ranks use the same numeric scale as global ranks.
Detailed definitions of each of the global and state ranks, along with details of the state and federal status, are available in each generated report. When the report window opens, the information categories are displayed in a large blue bar. Click on the text for any of the "federal", "state", or "global" categories for a key to the codes.
