About the Program


The Forestry and Natural Resources Graduate Program is one of the MS and PhD degree granting departments in Purdue’s College of Agriculture. Graduate students in FNR train alongside award-winning faculty and staff to become the next generation of professionals in the natural resource sciences. The department has well-established partnerships with FNR Industry Partners and offers a wide range of research possibilities. Graduates with advanced degrees in FNR are in demand in higher education, state and national governmental agencies, as well as private industry. Faculty and staff provide expertise in diverse areas, including Aquatic Sciences, Digital Natural Resources, Ecology of Natural Systems, Forest Science, Genetics, Hardwood Products Innovations, Natural Resource Social Science, Quantitative Ecology, and Wildlife Science.

Graduate students in FNR train alongside award-winning faculty and staff to become the next generation of professionals in the natural resource sciences. According to articles in the Chronicle of Higher Education and other literature including Science, broadening experiences in addition to research should be components of graduate education so that students may realize the breadth of potential professional opportunities and diverse interactions. FNR, consistent with the mission of a land-grant institution, strives to build programs that help graduate students realize diverse professional objectives. Graduate Students are the backbone of FNR by supporting all aspects of the land-grant missions of Discovery, Learning, and Engagement. FNR Graduate Students have the unique opportunity to create a Plan of Study that is tailored to their specific learning and professional goals.

Program Requirements


90 Credits Required

(30 credits from a Master’s may be applied.)

Required Courses (24-36 credits)*


*Students with an MS degree must complete 24 credits of coursework. Students without an MS must complete 36 credits of coursework.

Core Courses (0-5 credits)*


*Students who have already completed GRAD 61200 from a previous degree at Purdue University are not required to repeat the course. Additionally, students who have previously earned a FNR graduate degree are not required to repeat FNR 50600 or 59800.

Research Areas (24-31 credits)


Research areas include: aquatic sciences; digital natural resources; ecology of natural systems; forest science; genetics; hardwood products innovations; natural resource social science; quantitative ecology; and wildlife sciences.

Dissertation Research (15-60 credits)


A minimum of 15 credits of research hours is required.

Additional Requirements


Extension/Outreach: Students must:

1) complete FNR 50600 Theory and Application of Natural Resource Extension Programming; 

2) develop an extension/outreach plan; and

3) produce a minimum of one deliverable.

The outreach plan must include a defined target audience, clear learning objectives, and a suggestion of where and when their outreach and/or extension activity will occur. The specific deliverable(s) associated with each student’s outreach and/or extension activities will vary depending upon each student’s educational objectives and the direction given by each individual student’s Advisory Committee. Examples of deliverables include, but are not limited to: numbered extension publications, non-technical publications, articles in popular magazines, newsletter, trade magazines, etc., posters, pamphlets, web content, social media, workshops for professional or public audiences, seminars for non-scientific audiences, and youth programming. The student will complete and submit the Candidacy Extension/Outreach Evaluation Form.

If a waiver for FNR 50600 is obtained, the student is still required to meet the other policy standards including an Advisory Committee review and approval of an extension/outreach plan, an extension/outreach deliverable, and completion of the Candidacy Extension/Outreach Evaluation Form.

Presentation: Participation in scientific and professional conferences is essential to both understanding the state of the field and building professional networks. PhD students must complete a presentation related to their field-of-study at a national or international conference.

Article Submission: Students are strongly encouraged (but not required) to submit an article to a journal for publication prior to the PhD Final Examination.

Program Learning Outcomes


Students will:

  • Identify and conduct original research, scholarship, and creative endeavors.
  • Effectively communicate their field of study.
  • Think critically, creatively, and solve problems in field of study.
  • Conduct research in an ethical and responsible manner.
  • Demonstrate attributes of professional development consistent with expectations within field of study.

GPA Requirements


Graduate students whose cumulative grade point average (GPA) drops below 3.0 will be notified in writing that they have one semester to re-establish a minimum 3.0 cumulative index. Note, academic standing is not addressed during the summer semester. Should they fail to improve their cumulative index to 3.0 during the probationary semester, they will be dropped from the graduate program.

Additional Information


Preliminary Examination: The objective of the Preliminary Examination is to evaluate the breadth and depth of a student’s knowledge, to ascertain how well they can apply that knowledge, and to determine whether the examinee is qualified to progress to candidacy. The examination should be comprehensive in nature (i.e., the focus should not be exclusively on the student’s area of research). The examination must have a written and oral component.

Final Examination: After research has been completed and the dissertation written and presented to the committee, a final oral examination must be held in which the candidate defends the dissertation and demonstrates to the examining committee the capabilities for which the PhD degree is to be awarded.

  • Not all graduate programs may be actively recruiting students and course modality availability may vary. 
  • Please refer to the Explore Graduate Programs website for a list of currently available graduate programs.
  • Transfer credit policy: Credits earned for graduate study at other universities (both domestic and international) may be applied toward an advanced degree. Only credit hours associated with graduate courses for which grades of B- or better were obtained will be eligible for transfer. Any additional conditions under which credit transfers may be made are determined by the various departments.
