Course Description

Emphasizes the recognition and effects of diseases, insects and mammals affecting forest ecosystems in the Pacific Northwest. Course will examine the role of insects, diseases and animals in forest functioning, health and management, as well as control measures and integrated pest management. Lab work is largely field-based and emphasizes identification of damaging forest insects and diseases common in Oregon. Second course in the sequence of FOR 271, FOR 272, and FOR 273.

Course learning outcomes

1. Ability to describe and recognize stages of forest stand development.
2. Be able to apply crown classification system in even-aged stands.
3. Ability to interpret and use site index curves to determine forest site quality.
4. Be able to determine general growth patterns from examination of tree growth rings.
5. Be able to determine stand type from a diameter distribution graph.
6. Be able to collect diameter data and construct a diameter distribution graph.
7. Know how to properly use an increment borer to determine tree age.
8. Be familiar with silvicultural methods of regeneration and the kinds of stands they produce.
9. Understanding of basic terms, methods, and procedures involved in forest site preparation and tree planting.
10. Be able to correctly plant conifer seedlings.
