A Collaborative Database of the Plants from Western South Dakota
and Eastern Wyoming
Including the Bear Lodge Mountains and Black Hills

The term collaborative is important to note in the title of the database.  This work combines specimen data for our region from 16 herbaria and could not have been done without the support and cooperation of numerous curators/collection managers (listed below).  Nor could this project have been completed without funding from the National Fish and Wildlife Foundation and the National Science Foundation.

Over 65,000 specimens are included in the current database.  All South Dakota counties west of the Missouri River are included.  These are: Bennett, Butte, Corson, Custer, Dewey, Fall River, Gregory, Haakon, Harding, Jackson, Jones, Lawrence, Lyman, Meade, Mellette, Pennington, Perkins, Shannon, Stanley, Todd, Tripp, and Ziebach.  In Wyoming, Crook and Weston Counties are included.

All label data from vouchered specimens have been carefully entered.  Latitude, longitude and elevation have been added to localities in the database where possible.  At times it was not possible to obtain accurate longitude/latitude data for older specimens that lack sufficient location data.

Scientific names used in the database are taken from the USDA Plants website ( or the Flora of North America (  The word “species” is frequently used in our database to refer to the specific epithet.  We know this is not correct, but is it commonly used and its meaning is clear to most people. 

We hope that botanists, ecologists, land managers and the public will use this database.


NOTE: Species noted as sensitive by the USDA Forest Service or the South Dakota Department of Game, Fish and Parks or the Wyoming Natural Heritage Inventory are not available to the public on this database.  A list of the sensitive species can be obtained if you click here. Researchers who need access to locality data for these species can contact Grace Kostel, Herbarium Manager (  Comments and suggestions are appreciated and can be directed to Grace Kostel or Mark Gabel (

The National Fish and Wildlife Foundation is gratefully acknowledged for their generous financial support that allowed us to complete the database on the grasses of the region that was the foundation for the remainder of the work.

 We are eager to acknowledge the National Science Foundation for their support through grant number 0545102 for herbarium renovation and the bulk of the databasing project.

 We especially thank Ron Hartman at RM for permission to use their database system in an earlier version of this database.

 The curators/managers of the herbaria included in the database are thanked for their gracious hospitality upon our visits to their facilities or their willing cooperation on this project.  They are (in alphabetical order) Craig Beckner, Rachel Benton, Cissie Buckert, Beth Burkhart, Jack Butler, Megan Cherry, Tom Farrell, Craig Freeman, Ron Hartman, Gary Larson, Dan Licht, Neil Luebke, Tim Mullican, Ernie Nelson, Molly Nepokroeff, Bob Tatina, Cary Taylor, Dan Uresk, Bruce Weismann and Katherine Zacharkevics.
