The Forest Health Technology Enterprise Team’s Forest Insect and Pathogen Hazard Rating System Database is a collection of detailed summaries of insect and disease hazard and risk models and citations organized in a Microsoft Access relational database. It has been constructed to serve three primary users: (1) Field practitioners can use it to locate published literature for evaluating field conditions and making treatment prescriptions. (2) Researchers and other investigators will find it helpful when reviewing previous study methods and findings. (3) Groups doing strategic planning, such as that done for the National Insect and Disease Risk Map efforts, can use it as the basis for integrative modeling.
The core of this database consists of a number of tables linking detailed information about hazard rating models and their associated citations. Each rating system, or model, estimates some measure of risk or hazard to North American forest stands or trees from one or more insect or pathogen agent. For each model, the database catalogues information about:
- its documentation
- its spatial scope (e.g. tree-based, stand-based, etc.)
- its type (e.g. regression; CART, look-up table, simulation, etc)
- whether the model estimates the susceptibility or vulnerability of its scope
- what host tree species the model is applicable to
- its applicable geographic range
- its independent and dependent variables
The database application also contains hundreds of links to the models’ literature base via both internet hyperlinks and accompanying electronic PDFs.
