Scenario analysis can reveal the costs, benefits, and sensitivities of specific policies. Scenario analysis can demonstrate the landscape effects of policy decisions, and how applying the highest and best use principle can help clarify the best deci sion to make -- it is a decision support tool.

The Olympic Dam copper mine in Australia is one of the largest copper mines in the world; however, it is underground and has a land surface disturbance of only 13 square kilometers. In contrast, the Gold Strike gold mine in Nevada is an open pit mine with a land surface disturbance of 130 square kilometers.

A private sector entity could use such information to determine the potential return on an investment and whether it is great enough to warrant the initial investment and potential risk.

A greedy algorithm follows a problem-solving heuristic of making the locally optimal choice at different stages with the hope of finding a global optimum. The TNC project assessed habitat patches in terms of biodiversity, species richness, species rarity, habitat geometry, area effects, edge effects, and threats from development.

Extending the path model allows a landscape manager to consider other factors that would be affected by managing the forest structure in this way; however, there is much work needed in better understanding all the connections. There has been extensive work on fire management in the western United States, for example, but little progress made on using wildlife habitat suitability models to examine what that management means for biodiversity.

He provided an example of forest thinning from the guidebook, which positions various models (i.e., fire behavior, species distribution and population, and air plume models) between key elements of the path model (i.e., forest structure, fire behavior, species habitat, species population, and air quality)

It is useful, she added, to use a more conceptual model when there is more uncertainty in the data, and that it is not critical to have a robust decision; there can be a range of methods used to arrive at a decision without using complex models and conducting a rigorous uncertainty analysis.
