Advanced concepts about tree disease and its development, the role of tree disease in forest dynamics, and relevant characteristic of tree pests. Concepts are applied to common disease complexes found in Maine and other regions of North America. NOTE: Because of overlap, SFR 457 and SFR 557 cannot both be taken for degree credit. Lec 3.
Prerequisites: BIO 100 or SFR 100
Credits: 3
MEETING TIMES
Tuesdays: 4:10-6:40 pm
An alternate meeting time will be needed to make-up for cancelled days.

The web site contains class messages, files for lecture notes, links to required readings, recordings of lectures, previous exams, and some of the handouts.
E-Mail.
You will be receiving E-mail messages through your MaineStreet E-mail address. You may either check or forward your MaineStreet email by visiting http://mail.maine.edu . To forward your email to either FirstClass or another email account of your choice, select the option: "change the destination of email sent to your @Maine.edu address." More details about how accomplish this are at http://www.studentrecords.umaine.edu/mailforward.html
Lecture Readings and Recordings.
Text readings are available on-line or from e-reserve at the library. The readings are required. Lecture recordings are also on the web site and need to be viewed prior to class.
Readings are available on e-reserve. You will need your MaineStreet ID and password. Access the e-reserve at: http://aresum.foglerlibrary.org/ares/
Class Activities
At the start of each class period, you need to have available the notes and other material that you prepared for class. Failure to have prepared material will result in a loss of 10 points on the exam. You will be given a question or case study to discuss with 2 or 3 other students and to write a response. After 10-15 minutes, you will give the instructor the group’s answer. An open discussion will follow concerning acceptable responses as well as answering questions as needed. The process will be repeated with additional questions/case studies until the end of the class period. Group responses will be graded based on amount and quality of content.
Exams.
There will be two written exams and one final. Questions will require short, written responses and will cover material from readings, recordings, and class activities. Copies of previous exams are available on the class’s web site. The first two exams will be worth 100 points each. There will be a final exam given during final exams week and will be divided into two parts. The first part will have questions over material covered during weeks 12-14 of the semester and will be worth 40 points. The second part will cover all material from the class and will be worth 100 points.
Semester Project.
The objective of the semester project is to utilize knowledge concerning trees, insects, fungi, principals of disease, and principals of integrated pest management to develop a Tree Health Management Plan for improving and maintaining the health of a forest. You will develop the plan through four assignments over the course of the semester.

COMPLETION OF WORK
To earn credit for this class, all work must be completed. Also, any assignment turned in late will lose 10% of the grade value for each day late unless lateness is due to an excused absence.
DISABILITY NOTICE
If you have a disability for which you may be requesting an accommodation, please contact Ann Smith, Director of Disabilities Services, 121 East Annex, 581-2319, as early as possible in the term.
STUDENT BEHAVIOR
Every student in the class is expected to be familiar with the University's Student Conduct Code (http://www.umaine.edu/handbook/) part of which states, "It is expected that students will conduct their affairs with proper regard for the rights of others and of the University. All members of the University community share a responsibility for maintaining an environment where actions are guided by mutual respect, integrity, and reason." If the instructor believes that a student's behavior is violating this code or other codes in the Handbook, the instructor has the option to ask that the behavior cease and will seek advice from the appropriate office on campus on how to deal with the student's behavior.
ACADEMIC INTEGRITY
Academic dishonesty includes cheating, plagiarism and all forms of misrepresentation in academic work, and is unacceptable at The University of Maine. As stated in the University of Maine’s Student Conduct Code, plagiarism (the submission of another’s work without appropriate attribution) and cheating are violations of the code. An instructor who has probable cause or reason to believe a student has cheated may act upon such evidence, and should report the case to the supervising faculty member or the Department Chair for appropriate action.
If you have questions about this policy or want examples on what is acceptable and unacceptable behavior, please speak with the instructor.

Semester ProjectSFR 457/557 - Tree Pests and DiseaseFall 2013
I. Objective.
Develop a Health Management Plan that completely describes two disease complexes affecting a tree species and how they should be managed. .
II. Due dates:
Oct 22 / Semester Project Topics & References (5%)Nov 19 / Semester Project Draft #1 (30%)
Dec 10 / Semester Project Draft #2 (65%)
III. Procedure.
A. Each student will choose a set of pests (stresses) for a single tree species. The type of stand management (natural or plantation) will be designated by the student.
B. You can work in groups for researching and discussing the background material. However, each student must write his or her own presentation.
C. You will develop a presentation using PowerPoint or equivalent software. The presentation materials will be graded; you won’t being presenting the material to the class.
D. What to include in the presentation (use the headings in bold in your presentation).
1. Introduction:
a) State the economic and/or ecological importance of the tree species.
b) Indicate what are some of the problems, economic or biological, for the tree species and why. This is when you can mention:
(i) The disease complexes that will be the focus of the presentation.
(ii) The need for developing a health management plan.
2. Management Objective: statement on expectation for forests that are the subject of your presentation.
3. Tree species adaptations.
4. Disease Complex information: (complete for each complex)
a) Disease Complex Biology.
b) Disease Development.
c) Control Options
5. Health Management Plan: Integrated approach for managing the tree species in order to minimize the damage/disease caused by both pests (stresses).
a) Provide recommendations for:
(i) Pre-emptive strategies.
(ii) Monitor and survey.
(iii) Reactive strategies.
b) Provide rationale for what you recommend.
6. Conclusion: Summarize the important points of the presentation.
7. References:
a) You will need to use published references to find the information that you need. Many publications will also be found on web sites – it’s OK to use the electronic version, but do cite the information for the hard copy.
b) Web-only references must be approved by the instructor.
c) Any information that is taken from these references will have to be cited in the text at the place where it is used. Do this by placing the last name(s) of the authors with the date that it was published. Examples:
(i) (Manion 1991).
(ii) (Blanchard and Tatter 1981).
(iii) (Johnson and others 1992).
(iv) Use "and others" if more than two authors.
d) For minimum information on trees, check the "Silvics of North American Trees" which is on reserve in the library. A copy of the manual can be viewed on the internet at http://www.na.fs.fed.us/spfo/pubs/silvics_manual/table_of_contents.htm
e) Additional references should also be used.
f) For pests (stresses), use the computer data bases (Web of Science, AGRICOLA, Forestry Abstracts) in the library. Also, you can ask the instructors for information that they may have. Because more than one student may need to use the same reference, please do not check references out of the library. If you are having difficulty in finding a reference, please see the instructor.
g) Reference list: List the authors, year of publication, title, journal or publisher name, and pages used for each reference that you used. Some examples:
