Forestry FRST 307 – Biotic Disturbances
Course Outline – Fall 2017
|Instructors:||Dr. Richard Hamelin||Dr. Allan Carroll|

The objective of this course is to provide students with a biological basis for recognizing, diagnosing, and managing diseases and insects affecting forests and forest resources. Students will become familiar with the roles that insects and diseases play in natural ecosystem processes such as gap formation, nutrient cycling, and succession, as well as the challenges these biotic agents pose to sustainable management. The general principles of plant pathology, entomology, and pest management are introduced, followed by descriptions of the specific insects and disease agents involved.
Specifically, students will learn to:
- recognize and identify the major tree diseases and insects of the forests of the Pacific Northwest and to assess their actual or potential impacts on various forest resources;
- recognize and interpret insect and disease signs and symptoms of forest and shade trees around the world, with emphasis on boreal and temperate forests;
- understand the biology of some of the important forest insects and diseases of western North America, and consider the potential for climate change to affect pest biology and impacts;
- integrate forest pathology and entomology considerations appropriately into forest management plans.
Lectures: Monday, Wednesday and Friday at 11:00 to noon, MacLeod 202
Section 1 – Thursday 14:00 to 16:00, room FSC 1310
Section 2 – Thursday 16:00 to 18:00, room FSC 1310
Section 3 – Wednesday 15:00 to 17:00, room FSC 1310
To pass the course students must obtain at least 50 % overall. Students who miss an exam or are unable to complete an assignment by the due date must contact the Instructor at the earliest possible date to determine whether a suitable accommodation can be made. Failure to do so will result in a grade of zero.
Lecture notes will be posted on the course web site at least one hour before each lecture. Please note that while the posted lecture notes will be comprehensive, they will not necessarily capture all of the information delivered verbally by the Instructor for which students will be responsible during exams.

Handbooks and Field Guides
These resources are useful for identification of specific biotic agents in western forests, and often provide short discussions of biology and management. All are available from the MacMillan Library. Most can be obtained free of charge by writing to the relevant agencies.
