The component hazards are integrated in two steps.
- The first box grid integrates topographic exposure and soil hazards
which are intrinsic and constant, to yield 'Site Hazard.'
- The site hazard is integrated with stand hazard, which changes as
stands grow and management practices are applied. When brought together
in the second box grid, they yield 'Overall Hazard.'
The integration is conservative. Integrating a moderate and a high yields
a high class. The results of the biophysical hazard assessment should
be checked in the field during the 'calibration' step and adjusted if
