Root Disease Management Course - FIELD SESSION 2

DAY 2 - Field Session 2 Participant Objectives:
 Performance/Observance of Steps 2 & 3 of the Five-Phase Management Process - About 4 hrs.
A. Perform a Silviculture Prescription Walkthrough Reconnaissance
B Determine the level of disease
C. Recommend for or against a survey, and a survey method
D. Observe a survey which has been prearranged
E. Observe the forest site and disease conditions where data were collected for use In Classroom Session 3

 -Learn how to conduct a field reconnaissance (walkthrough) and record requisite information.

-Learn how to determine threshold levels of a root disease infestation under field conditions and when to conduct a survey.

-Become familiar with the types of survey methods which can be used under regional and site circumstances and their strengths and weaknesses.



 Preparation and Instructions Exercise/Discussion

You are responsible for making all arrangements for Field Session 2 including (for a complete list, see the Preface):

· selecting the site (s)

· conducting an appropriate survey beforehand for participant observation (participants will not be conducting an actual survey)

· collecting data from your survey for use in Classroom Session 3, steps 4 and 5.

· preparing to lecture on Steps 2 and 3 of the Five-Phase Management Process

· arranging transportation

· Providing lunches if participants are from out of town

· reminding participants to bring/wear appropriate equipment as well as their RDM Guidebooks and the Field Guide to Pests.

You should encourage the use of the disease assessment tools in the RDM Guidebook during this field session. Review these tools with the participants:

· Hazard and Risk Tables pp 58-63

· Survey methods pp 27-3

· Perform a silviculture walkthrough assessment and discuss results in view of the threshold tables on pages 37 and 38 of the RDM Guidebook (step 2). If you have already discussed Steps 2 and 3 in some detail during Field Session 1, you may want to divide your participants into groups and have them conduct their own walkthroughs, reporting back to the group with their results.

· Based on walkthrough observations, determine whether survey is necessary; if so, discuss the types of surveys which would be suitable and the reasons supporting this recommendation (preparing for step 3).

· Examine the survey which you, the instructor, have conducted ahead of time.

· Visually assess the results of the instructor's prepared survey.

· Discuss the reasons why this survey tvpe was chosen.

· Observe forest site and disease conditions where data were collected which will be used in Classroom Session 4.




In this section, participants will ACTIVELY APPLY Steps 4 and 5 of the Five-Phase Management Process to the observations and data collected from Field Session 2.

After presenting lecture and discussion points, participants can be asked to work alone or in groups to develop a future stand risk assessment and a final prescription using the data from the field session and the RDM Guidebook. Participants should be very involved in developing the solutions for the disease observed in the field session.

Key points and overheads have been prepared for this section in order to help you promote discussion. In addition, you may want to review the material presented earlier on steps 4 and 5 of the FivePhase Management Process; simply refer to the previous sections of this guide. You may also want to use the associated overheads again.

As you are assisting participants to develop their prescriptions, emphasize again that the RDM Guidebook is a tool to be used as guide for the root disease management process.
