The Department of Biology at Georgia Southwestern State University aims to provide students with a comprehensive education that cultivates lifelong learning through the application of scientific knowledge. 

Students learn the fundamentals of biology and implement them through applied pedagogy and undergraduate research.  Through this instruction they develop the critical-thinking skills necessary to assimilate, interpret and communicate scientific knowledge. The students become competitive for the best opportunities available following graduation, including professional and graduate school programs.

The GSW Herbarium has an impressive collection of over 13,000 cataloged specimen.

This is an interesting collection since the majority of the specimen are non-local flora with most being from California and Utah.  The bulk of the collection was donated to GSW by Dr. Robert A. Norris and is referred to as the Norris Collection.

Current work in the herbarium is focused on the digitization of the Norris Collection.  Each specimen will be imaged and the label information will be entered into Symbiota hosted by SERNEC.  Symbiota provides a web portal to the data so that it can be search by individuals around the globe.  To access the entered collection information, you can go to and limit your search to the GSW Herbarium.  This is a labor intensive process and currently less than 5% of the collection in the portal.

More about Dr. Norris

Dr NorrisDr. Norris had a Ph.D. in biology and was a professor at Valdosta State University, Rutgers University and University of California at Berkeley.  For over 30 years, he collected and traded his specimen with other intuitions.  After donating his collection to the university, Dr. Norris continued to work with it and served as its curator until his death in 2010. Georgia Southwestern State University  is honored to house the Norris Collection and appreciates all his labor and devotion to this project. He will be missed.

Field trips are an important component of the learning experience in Biology at GSW.  A simple walk outside the classroom can add an entirely new prospective to a topic. Field trips provide the  opportunity to experience new habitats and to appreciated the diversity of the natural world.

Weekend camping trips allow for further travels.  Students can experience environments as vastly different as the long-leaf pine/wiregrass ecosystem of Northern Florida and the lush growth of a temperate forest along the ridges and valleys of North Georgia. From the sandy shores of St. George Island to the maritime forest of Sapelo Island, the wonders of nature energize students and faculty alike.

Weekend trips are typically associated with field classes so most of these trips occur during the Spring semester.  Student in the associated class are given first refusal, but if space allows other students can participate.  There is typically a fee to cover food and campsite cost.
