MOHIEF
Modelling of heterobasidion infection in European forests: A decision-support tool for the forest manager

This project will bring together a range of experts to prepare a prototype decision-support tool for determining losses to Heterobasidion infection and decay in the range of forest types found in Europe. The project will establish the output requirements of the end users, collate the biological and management inputs required and construct a prototype simulation model, concentrating on adaptability and user-friendliness. The project is perceived as a data collating and basic model construction prelude to the development of a full model and extensive field-testing under a future research programme.

Objectives
The objectives of this project are:
1) to bring together leading forest root disease pathologists, forest ecologists, forest modellers and forest managers from across Europe to determine the requirements of the model. Input will also be sought from forest pathologists in the USA who developed the 'Western Root Disease Model' for forests on the Pacific coast of North America
2) to define the outputs required from the model by forest managers
3) to gather the data required for the model inputs from published and unpublished sources
4) to construct prototypes for the user-interface and decision-support system of the model
5) to adjust the prototype model in the light of test results.

Progress to Date
The following have been achieved:
1) Definition of model output requirements.
2) Completion of input requirements for the model, including stand development model type, logging injury data, infection frequency data, and disease development data.
3) Production of simulation model prototype 1 and decision-support system prototype 1.
Tests with end user groups (forest managers) are currently being organised.

Results
Information on output requirements was supplied by forest managers involved in the project. Important factors for further consideration were the types of growth models used in the various forest ecosystems of Europe, the scale of detail required in the outputs and whether the model should provide a comprehensive description of its results, rather than simply data output.
The programming parameters, defaults and assumptions to be used as the basis for the future work were established. Development of the prototype led to improvements in the accuracy of the model. The prototype consists of a PC-based simulation model prototype, and a decision-support system prototype.
