Root Disease Management Course - Step 1 of the Five-Phase Management Process (optional)

DAY 1 - Classroom Session 1 Participant Objectives:

 The Forest Practices Code Root Disease Management Guide Book:

A. The Role of the RDM Guide Book -
About 10 min.
B. What the RDM Guide Book Contains - About 20 min.
The Role and Impact of Root Disease - About 30 min.
Step 1 of the 5-Phase Management Process (optional) - About 30 min.
Root Disease Identification - About 1 hr.

 - Understand and be able to explain the role of the RDM Guide.

- Leam how to consider root disease in silviculture and stand management prescriptions.

- Be able to assess the inherent root disease risk in a particular zone.

- Become familiar with the appearance of the three main root diseases in B. C. under various conditions and in various species.



 If you are presenting Field Session 1 before Classroom Session 2, you should present step 1 of the FivePhase Management Process in greater detail now. This section is followed by an exercise.

If, however, you are representing Field Session 1 AFTER Classroom Session 2, then present this section along with the other steps of the FivePhase Management Process, that is, at the beginning of Classroom Session 2.

Note that this section begins and ends on its own pages so you can move it to the appropriate point in the guide.

You should keep the lecture portion of this section brief and spend most of your time on the exercise which appears at the end of this section.

Refer to RDM Guidebook p 23


The intent of this section is to familiarize the participants with an essential part of the Five-Phase Management Process before the first Field Session; note that this is an office-based procedure.

Continue to encourage use of the RDM Guidebook when managing root disease


REMINDER: Overheads of most tables and maps in the RDM Guidebook are provided in your Instructor's package. You can show some of them now if you want.



STEP 1 of the Five-Phase Management Process: Landscape Level Hazard and Risk Assessment

· This assessment should also be included in Forest Development Plans or other higher level plans

· Is a preliminary assessment conducted in the office, provides a reasonable level of guidance

· Is not to be considered the sole evaluation

· Consider two key factors:

A. The hazard inherent in the ecosystem at the biogeoclimatic subzone level and the susceptibility of the indicated forest cover; and
B. The risk (or probability of root disease and its expected damage impact) in a polygon or block

· Forest pathologists have considered these factors in the RDM Guidebook's Hazard and Risk tables

- Tables are in Section 9.0 of guide, beginning on page 58
- Each table identifies regional high hazard biogeoclimatic subzones that have a high probability of root disease occurrence and which will require evaluation as part of the prescription process


1. Conduct a Landscape Hazard Risk Assessment for your region using the tables in Section 9 of the RDM Guidebook.

2. Conduct an assessment for the particular site that you will be observing in Field Session 1.

3. If your participants come from various regions, assess the hazard in each region.

4. Discuss other factors that may influence the inherent risk such as species type, age of trees, past forest practices, etc.
