Applied Systematics in Botany Graduate Major

The worlds of science and business are increasingly interconnected, creating strong demand for individuals who can bridge these two disciplines. Systematics is the science devoted to the discovery, description, and classification of the earth’s biological diversity. The need for an accurate and comprehensive knowledge of biological diversity is now recognized by a broad array of interests in the public and private sectors. Plants and fungi are the focus of current initiatives in the conservation of endangered species, the restoration of native ecosystems, and the control of invasive weeds. Industry, private environmental consulting firms, and government agencies have an increasing need for individuals with expertise in plant identification and experience in survey techniques.
