Model Input (Forest Parameter Surfaces)
The National Insect and Disease Risk Map project (NIDRM) was driven by the 188 models which attempt to predict how individual tree species will react to various mortality agents. The models, in turn, are the interactions of predicted agent behavior with known forest parameters (criteria).
GIS Grids: Individual Species Surfaces
Compressed as ZIP files.
The most widely used forest parameters for NIDRM were stand basal area (BA), stand density index (SDI), and tree diameter or its surrogate, quadratic mean diameter (QMD). Plot data were interpolated to create uniform 'surfaces' that capture natural variations in forest parameters. The GIS grids can be downloaded below.

Individual Model Criteria and Output Maps Contributing to NIDRM

Each of the 188 models which predict the reaction of 42 mortality agents acting on 57 tree species were documented using a spreadsheet template. The model results for each agent/host interaction are represented by a pair of maps showing:

  • the likelihood (on a scale of 0 - 10) of an agent/host interaction resulting in mortality.
  • the percent contribution to total basal area loss attributed to that model.

Following are the triplets of spreadsheets and maps broken out by regions.
