Terrestrial Model and Impacts
The terrestrial ecology model assesses the impacts of the Alternative
Futures on different
vegetation and habitat categories. New land uses of the Alternative
Futures are aggregated into
groups based upon their impacts associated with construction,
maintenance and use.
The impacts of terrestrial model are assessed by location. The model
considers both the degree
of change and the underlying ecological value of the impacted area.
Three levels of impact are
reported for this model:
- Moderate: natural mitigation
possible
- Severe: mitigation possible with
major engineering
- Terminal: no possible mitigation
Figure 21 shows the impact on
terrestrial ecology of Plan Propuesto at a population of 120,000.
The results of the terrestrial ecology model for the twenty-five
Alternative Futures are summarized
by totaling the impact scoring for each pixel on the map and shown in
Figure 22.
