 Instructions  Key Points  Visual Aid

The intent of this section is to familiarize participants with the high- level contents of the RDM Guidebook.

















Emphasize that one of the main reasons for developing this course is to introduce the Five- Phase Root Disease Management Process to forest professionals throughout the province.










If time allows, you may want to add a bit more detail about what the various steps entail.


However, this information will be covered in detail later in the course.

















Ask your participants if they can name and describe steps 1, 2, and 3.

Refer to RDM GuideBook pp 58-63




Refer to RDM Guidebook pp 27-35





Refer to RDM Guidebook pp 37-38

Discuss why these tools are used in steps 2 and 3.

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.


Refer to RDM Guidebook pp 8-20

Discuss why these tools are used in steps 2 and 3.

If you have brought copies of these additional resources, you may want to show them now to your participants .


· Recommended procedures, processes, andexpected results

· Information to make site-specific interpretations and modifications within the restrictions and limits set by the Code

· The best direction available when it was produced (but does not have to be rigidly adhered to)

Types of diseases discussed in the guide

Pathogen - - - - - - - - Code

Laminated - - - - - - - - - DRL

Tomentosus - - - - - - - -DRT

Armillaria - - - - - - - - - DRA

· Easy to remember which disease is referred to by a code's last letter.

Other diseases included are Blackstain root disease and Annosus root disease but the three listed above are the main topics of discussion

The RDM Guidebook and the Five-Phase Management Process

· The RDM Guidebook outlines the Five-Phase Management Process. The steps are:

1. Landscape Level Hazard and Risk Assessment

2. Silviculture Prescription Walkthrough Reconnaissance

3. a. Disease Assessment Survey

b. Stratification

4. Future Stand Risk Assessment

5. Evaluation and Final Prescription

A. The first three steps determine the level of the disease:

1) Landscape level hazard and risk assessment

- an office exercise to evaluate your biogeoclimatic unit

2) Silviculture prescription walkthrough reconnaissance

- walk through the site and visually assess the level of disease

- decide whether or not to survey, or go directly to Stratification and following steps

3) a. Disease assessment survey

- if needed, accurately evaluate the level of disease with an appropriate survey method

3) b. Stratification (Stratification is always necessary, even if block is only one strata)

B. The last two steps help you decide how to treat the disease

4) Future stand risk assessment

- consider various factors such as disease type, host, environment, and management objectives

5) Evaluation and final prescription

-consider various factors such as management objectives, site constraints, level and type of disease, and various strategies and tactics .

The RDM Guidebook provides tools and support for the Five-Phase Management Process

The RDM Guidebook's Disease Assessment Tools

· Are used in steps 1, 2 and 3

· Hazard and Risk Tables

- to evaluate your biogeoclimatic zone

· Survey methods

- Different methods are used under different circumstances

- RDM Guidebook includes detailed instructions on how to conduct surveys

- Formal surveys provide a more accurate estimate of the amount of disease present (degree of accuracy varies between surveys)

· Threshold tables

- Are used for both Steps 2 and 3

- Help you to determine need for survey using Reconnaissance survey threshold levels .

- Are also used to determine minimal, alternate, or intensive disease treatment based on formal survey results

The RDM Guidebook's Disease Identification Tools

· Are used in steps 2 and 3

· Distribution maps

· Table: Root Disease and Host Susceptibility

· Table: Signs and Symptoms of Disease

The RDM Guidebook's Disease Prescription Development Tools

· Are used in steps 4 and 5

· Table: Mode of Infection and Spread

· Table: Host Susceptibility

· Discussion of Disease dynamics

· Detailed information on treatment levels, strategies, and tactics

The RDM Guidebook's Free Growing Guidelines

· Free Growing Guidelines will not be discussed in this course

· Discuss other MOF identification tools such as Field Guide to Pests... which will be useful to participants as they are learning how to identify and manage root disease.

· Tell participants about the resource centres provided by MOF where they can get more information about root disease.
