Excerpt from The Wilderness Threats Matrix: A Framework for Assessing Impacts
The impacts caused by any single threat will differ depending on the attributes the threat impacts. For example, grazing's impacts on vegetation differ from grazing's impacts on native animals. The impacts of different threats on a single attribute will also differ. For example, the effects of air pollution on vegetation differ from the effects of fire suppression on vegeta tion. Consequently, managers need to understand the linkages between each significant potential threat and each individual wilderness attribute. Figure 1 dis plays linkages for eight potentially significant threats to wilderness. Other threats are represented as well. Finally, these potential threats will interact, causing cumulative impacts; the figure recognizes these interactions.
