Most land management policies, such as land retirement, have multiple objectives. This study uses a cellular automata simulation model to explore how various spatial characteristics of land parcels on a hypothetical landscape contribute to efficacy of land retirement in the presence of multiple retirement objectives—hydrological improvement, habitat improvement, and cost. Statistical analysis of the simulation results is used to tie particular spatial characteristics back to achievement of the three distinct objectives. In order to combine the three objectives into a measure that allows decision-makers to rank the desirability of different retirement strategies, linear and nonlinear goal programming frameworks are introduced. These frameworks are explored to determine what each implies about the tradeoffs that must be made among objectives and among the spatial land parcel characteristics that contribute to those objectives. When one of those objectives is expressed in monetary units, these tradeoffs illustrate what a particular decision-making framework implies about the “worth” of other measures of absolute and relative location. These tradeoffs are then used to formulate heuristic devices that could enable decision-makers to compare land retirement alternatives on an actual landscape. Uncertainty in the statistical estimation of the relationship between cell characteristics and cell performance results in imprecision in the predictive power of those heuristics, so there is a cost entailed with using heuristics rather than directly simulating results; these costs are also compared with the costs of using other naive ranking schemes, such as retiring the cheapest or most downstream parcels first.
