Root Disease Management Course - The Five-Phase Management Process


DAY 2 - Classroom Session 3 Participant Objectives:
Evaluation, Future Stand Risk Assessment, and Final Prescription Total about 3 hrs.
A. Future Stand Risk Assessment
B. Root Disease Treatment Level Evaluation
C. Treatment Methods: Strategies and Tactics

Demonstrate familiarity with the factors that influence future stand risk assessment, and how future stand risk assessment impacts prescription.

Demonstrate efficacy in the process of evaluating a root disease infestation and prescribing appropriate treatment

Recommend a disease treatment level, a treatment strategy and tactic based on survey results from Field Session 2.

 Instructions  Key Points  Visual Aid

If desired, review material on Future Stand Risk Assessment covered earlier (Step 4).

 

 

 

 

 

 

Ask the participants to develop a future stand risk assessment based on observations in Field Session 2.

 

Use these points to promote discussion .

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Discuss how and why Step 4 must be closely integrated with Step 5.


If desired, review material on determining Treatment Levels (part of Step 5).

Refer to RDM Guidebook pp 26-43.

Supplement the review with the additional discussion points generated by OHs 21 and 22, and refer to the RDM Guidebook for more information on treatment levels; (do so in light of observations and data from Field Session 2.)

 

Walk participants through the steps for determining a treatment level for the disease observed in Field Session 2.


If desired review material on determining Treatment Strategies and Tactics.

Refer to RDM Guidebook pp 44-53 guide Supplement the review with the additional points below on Evaluation and Final Prescription: do so in light of observations and data from Field Session 2.

DEVELOPING A FUTURE STAND RISK ASSESSMENT


Refer to material presented earlier in this guide

Supplement the review with the additional discussion points below on Future Stand Risk Assessment; do so in light of observations and data from Field Session 2.


When conducting a future risk assessment, consider these factors:

Damaging Agent

· How much and what type of root disease is there?

The incidence level of root disease, by strata

Resident or transient

Population and proximity

Potential

How do we fix it?

Recommended disease management strategies and tactics

 

Potential Host

What is on the site now, and what will be on site later?

The existing and future host tree population (susceptibility/hazard, number and size, successional stage, desired future stand structure)

Availability

Stand structure and composition

Environment

Where is the site?

The biogeoclimatic area: subzone, variant, site series

Physical site character

Past management

Time

· How has/will the stand be managed?

How past, present, and future stand management practices affect root disease Incidence levels

· Integration of process with Phase 5 (below)


DETERMINING TREATMENT LEVELS

 

· Refer to material presented earlier in this guide

Generallv review treatment levels for various diseases and levels

· Determine an appropriate level of treatment for the disease observed in Field Session 2 by using the threshold tables

Survey Method +

Disease Type +

Coast Or Interior +

Disease Level =

Treatment Level


DEVELOPING STRATEGIES AND TACTICS

· Refer to material presented earlier in this

· Generally discuss various strategies, tactics, and constraining factors


FINAL EXERCISE

 

Ask participants to prepare a final prescription andsupporting reasons based on:

a. field observations from Field Session 2

b. hypothetical scenarios

Considerations.

Management objectives

Treatment Strategies and tactics

Impact of forestry practices

Future Stand Risk Assessment

Constraining factors

Disease level

Species type

Other non-timber resource values

Ideas to keep in mind while answering questions

l . How does the prescription fit in with stand objectives?

2. Why is this prescription the best?

3. What are the limitations of the prescription?

4. What are the expected consequences?

5. What additional information would yotl like to have to improve your prescription?
