Welcome

Reis Biological Field Station is managed by the Biology Department of Saint Louis University in St. Louis, MO.  The station comprises ca. 225 acres of upland oak-hickory forest in the eastern Ozarks of Missouri, approximately 100 miles southwest of St. Louis.  The station is contained within one of the seven subdivisions of the 1.5 million acre Mark Twain National Forest.  Huzzah Creek, a major tributary of the Meramec River, flows through the station property providing an excellent site for the study of aquatic ecosystems.  On the station and within the national forest can be found a diversity of ecosystems including shortleaf pine forest, calcareous fens, glades, caves, springs, ponds and rivers.

This site was initiated as part of a class project for BIOL-412, Field Botany.  As part of the course, registrants will construct taxon pages for the flora of the station.
