Range Science - PhD


S.J. and Jessie E. Quinney College of Natural Resources

Department of Wildland Resources

Students in this program study the science and application of ecological principles in rangeland environments. While the focus of range sciences at USU is primarily on the rangelands of the Great Basin, students will receive a broad background in various subjects in rangeland ecosystems. Students can study specific areas related to rangeland science, such as vegetation management, animal behavior, range ruminant nutrition, and restoration of rangelands. The program is integrated with other natural resource programs in the college focusing on forestry, wildlife, and ecology for a broad interdisciplinary experience.

The PhD degree is intended for students seeking a research or academic career in rangeland science. The Range Science PhD degree may be obtained through either a post-master’s or post-baccalaureate program.

Admission Requirements

To be accepted into the Range Science program, applicants need to find a departmental faculty member that agrees to serve as their major advisor. It is recommended that applicants first contact specific faculty members with whom they are interested in working.  If the faculty member is accepting graduate students and agrees to work with the student, the student can then apply by completing the following application requirements.

  • Official transcript indicating a bachelor’s degree in an accredited U.S. college or university or a similarly recognized international university. Students with undergraduate and/or master’s degrees in natural resources preferred.
  • GPA of 3.0 (calculated using all grades from last 60 semester or 90 quarter credits earned)
  • 3 letters of recommendation.
  • Statement of purpose
  • International students - proof of English proficiency (TOEFL or IELTS)
