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).

INDIVIDUAL SPECIES SURFACES (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 representing the most widely-used criteria (forest parameters) for all 57 tree species and species groups are below.

QMD:

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.

OUTPUT GIS GRIDS

The final output grids are:

Basal Area (BA) Loss (zip files):

The grid of total BA losses from all models (and individually for the 11 most significant mortality agents).

TOTAL:

Alaska (83 KB ZIP)
Contiguous United States (1.6 MB ZIP)

PRIMARY CONTRIBUTING AGENTS:

Alaska (65 KB ZIP)
Contiguous United States (3.35 MB ZIP)

PERCENT OF TOTAL BA LOSS (zip files):

The grid of total BA losses from all models divided by the grid of Total BA, expressed as percent. (All areas at greater than or equal to 25 percent are considered at risk.)

Alaska (269 KB ZIP)
Contiguous United States (2.45 MB ZIP)

Areas at Risk (Presence / Absence) (zip files):

The grid of Percent of Total of BA Loss broken into two classes in accordance with the definition of risk of mortality: areas with less than 25 percent mortality risk are not at risk and areas with 25 percent or more are at risk.
