Forestry by the Numbers
A Workshop on Computer Models in Forest Management Planning

Friday, November 26th, North Bay

Forest management planning in Ontario relies heavily on the use of computer models to identify candidate areas for harvest, estimate future available harvest, and predict the availability of future wildlife habitat.  Many planning participants have only a very general understanding of the models and how they work, and find it difficult to interpret the model outcomes, assess the reliability of inputs or outputs, or evaluate the effectiveness of the models in providing information about the forest's sustainabilty.

This goal of this one day workshop is to make computer models and their use in forest management planning make sense to forest management planning participants. We'll learn how they work, how they're used, and how to evaluate the computer predictions that are the basis for forest management planning.

Friday, November 26th, 2004 - 9 a.m. to 5 p.m.

Workshop Leader: Dr. David Euler

Location: Caldwell Ellen Community Centre, 398 Carruthers Street, North Bay

Hosted by Northwatch's Forest Project

Registration is limited to 25

Limited travel subsidies may be available to those who request assistance prior to November 16th.
There is no registration fee, but pre-registration by November 19th is required.

Goal: The main purpose of the workshop is to provide participants with the confidence to deal with obscure models, to judge whether the results of the model have a measure of validity and the ability to ask questions to better understand the model.

8:30 Registrations and Coffee

9:00  Workshop and Participants Introductions

9:15 Understanding Forest Management Models and How They Work

An opening presentation that describes and illustrates the concept of  computer models, often called "information management systems".  A discussion of the basic idea behind these systems, how they are constructed and how they are intended to assist in forest management planning.  This opening presentation will form the basis for other discussions during the day, including terms used by modelers, and the conceptual framework that modelers use.

10:15 BREAK

10:30 Building a simple model

In order to build confidence on the part of participants, we will build a simple model that links harvest to wildlife habitat. Each participant will be able to see and understand the assumptions behind the model, how the calculations are developed, and how easy it is to manipulate the information used in the model.

12:00 LUNCH

1:00 Do Models Help Foresters Plan for a Sustainable Forest?
 A Panel Discussion of the Strengths and Weaknesses of Forest Modeling

A panel of speakers from different sectors and disciplines (ie. Ministry of Natural Resources, independent audit teams, forest industry / biologists, foresters, planners) discuss the key strengths and weaknesses of models being used in forest management planning in Ontario today.

2:30 BREAK

2:45 Asking questions about models

In this session we will build a series of questions that anyone can ask about a model, and which will help evaluate how much confidence an observer can have in the model.

3:30 Making Models Make Sense

A closing discussion on how participants can practically apply what they have learned in the workshop in a forest management planning context, as members of Local Citizens' Committees, Forest Management Planning Teams or public participants.

4:15 Closing Comments

Workshop Leader: Dr. David Euler worked as a Wildlife Habitat Biologist for the Ontario Ministry of Natural Resources (OMNR), was a Research Scientist and then became a Senior Policy Advisor in the Forest Management Branch.  He developed guidelines for moose and deer management, served on several forest policy committees in the Ministry and was part of the team that wrote the Crown Forest Sustainability Act and the forest management planning manual. In 1995 he became Dean of the Faculty of Forestry and the Forest Environment at Lakehead University.  He has published scientific papers on forest - wildlife habitat management, and recently was an editor and chapter author of a book titled "The Ecology of A Managed Terrestrial Landscape: Patterns and Process in the Forests of Ontario".  He is part of a group developing standards for certification in the Boreal Forest in Ontario using the principles of the Forest Stewardship Council. Following retirement from Lakehead University on December 31, 2000, Dr Euler has participated in projects as a Consultant, reviewing current forest management guidelines and the Independent Forest Audit Protocol, advising the OMNR on how best to implement a spatially explicit forest management planning model.  He has also participated in auditing Forest Management Plans for the last three years.

The Forest Project: Northwatch's Forest Project supports public participation in the forest management planning process in northeastern Ontario with a number of education and information services, including a quarterly newsletter, a web site, workshops, regional and local networking, and an email list serve, as well as one-on-one support and assistance.
