The School, which includes the Departments of Forestry, Wildlife and Range Sciences, and Fisheries and Aquaculture, offers programs leading to the de- grees of Master of Science, Master of Forest Resources and Conservation (nonthesis), and Doctor of Philoso- phy. Programs are.offered in the following areas of spe- cialization: Forestry-biometrics, biotechnology, ecology, economics, genetics, hydrology, manage- ment, nutrition, pathology, physiology, silviculture, soils, and wood products; Wildlife and Range Sci- ences -biology, wildlife diseases, ecology, and man- agement; Fisheries and Aquaculture-biology, ecol- ogy, limnology, and management. Graduate faculty include personnel with the U.S. Fish and Wildlife Service's Cooperative Fish and Wild- life Research Unit, the U.S. Forest Service, other feder- al and state agencies, and related departments on campus. Graduate students should have appropriate under- graduate training in biological, social, and physical sciences, including physics, chemistry, and mathemat- ics. Students with inadequate backgrounds may be required to take (without credit at the graduate level) undergraduate courses pertinent to their field of in- terest.
