Forest Science, Doctor of Philosophy
- Available Emphasis Areas:
- Ecology, Evolution and Conservation Biology - Emphasis
- Forest Science Coursework
This is the terminal degree in the profession of forestry, and it prepares you for a career in research and/or education. We offer three concentrations within this doctoral plan-ecosystem science, forest management sciences and economics, and forest social science.
For this plan, which involves completing a dissertation, we expect you to demonstrate your skill in generating original ideas; your considerable command of the literature; your skill at designing, analyzing, and interpreting research; your skill in scientific writing, including publication of research results in major professional refereed journals; and your basic skills in teaching. We expect you to be self-motivated and to largely direct your own research program with advice and counsel from your major professor and dissertation committee. We evaluate your work on the basis of the originality and quality of the new knowledge you generate.
What Can I Do with a Doctor of Philosophy in Forest Science?
The Forest Science PhD degree is the terminal degree offered in the profession of forestry. Students with the PhD degree normally pursue a career in research and/or education. PhD students are expected to demonstrate skill in the generation of original ideas, considerable command of the literature, skill at designing, analyzing, and interpreting research, skill in scientific writing including the publication of research results in major professional refereed journals and basic skills in teaching.
To receive a Doctor of Philosophy Degree (PhD) at Northern Arizona University, you must complete a planned group of courses, from one or more disciplines, ranging from at least 60-109 units of graduate-level courses. Most plans require research, a dissertation, and comprehensive exams. All plans have residency requirements regarding time spent on the Flagstaff campus engaged in full-time study.
The full policy can be viewed here.
In addition to University Requirements:

The Doctor of Philosophy in Forestry (PhD) is the terminal degree offered in the profession of Forestry. The PhD prepares students to be professional researchers and educators by extensive study of Forestry and the development of original scientific research and knowledge through the completion of the dissertation. The PhD trains students for positions such as professor, instructor, conservation specialist, post-doctoral researcher, and forest health specialist in governmental and non-governmental agencies and organizations.
The PhD program is appropriate for students with a Master’s degree in Forestry or closely related disciplines. Students lacking a Master’s but having a Bachelor’s degree may be eligible for admission if they have significant research and experience beyond the Bachelor’s degree. PhD students are expected to generate original scientific ideas and knowledge, have a command of the literature, and have advanced skills in designing, analyzing, and interpreting research, scientific writing, and college teaching.
The PhD program emphasizes training in the focus areas of ecosystem, forest management, and forest social sciences; college teaching; research methods and statistics; quantitative analysis; professional presentations; emerging issues in forestry; and electives that provide advanced training in specific skills. The dissertation showcases student’s command of the literature; generation of original scientific ideas; research design, execution, analysis, and interpretation; and scientific writing.
Student Learning Outcomes
Students completing the PhD will have the following competencies:
- Demonstrate the ability to apply graduate level critical thinking skills to identify, explain, synthesize and solve complex professional forestry problems through acquisition and application of fundamental knowledge of forest ecosystems and human management of forests
- Demonstrate mastery about a specific research topic in forest science (dissertation topic)
- Apply an understanding of professional ethics to forest research and professional activities
- Design a forestry research study including planning, organizing, scheduling and executing the project
- Design and execute a forest science research project that seeks to generate new knowledge and advance the scientific understanding of forests
- Select, implement and interpret appropriate methods and statistical analyses for research projects
- Effectively communicate through written, oral and visual means, a forest science research project, demonstrating the ability to communicate forest science research to technical and non-technical audiences
- Design and implement a college-level course in the forest sciences or related fields, using innovative and learner-centered teaching approaches
The PhD includes an optional multi-disciplinary emphasis in Ecology, Evolution, and Conservation Biology (EECB). The EECB emphasis provides a structured curriculum for students wanting to focus on ecology and conservation biology within the context of forest science. The course requirements of the EECB are designed to be taken as elective hours within the PhD degree. Students completing the EECB emphasis will have the following competencies in addition to those described above for the PhD degree:
- Demonstrate the ability to synthesize and discuss the history and conceptual and theoretical foundations of ecology
- Demonstrate the ability to discuss current and emerging topics in ecology, evolution, and conservation biology with peers and experts
- Demonstrate the ability to use quantitative research approaches in ecology, evolution, and conservation biology
- Demonstrate an understanding of ecology, evolution, and conservation biology at physiological, population, and community scales
- Demonstrate an understanding of ecology, evolution, and conservation biology at ecosystem and global scales

Research Competency Requirement
Northern Arizona University policy for Ph.D. programs includes a Research Competency requirement that must be satisfied before a student can be admitted to candidacy. In most departments, this is enforced as a requirement to demonstrate an ability to translate disciplinary literature from a foreign language into English. The School of Forestry has chosen to recognize FOR 690, STA 570 (or equivalent), plus one graduate-level course with significant content in statistics, as meeting this requirement.
