The impacts of adjacency restrictions as a component of a set of ecosystem management guidelines are assessed for a public forest in Florida using an integer programming harvest scheduling model. Results show that depending upon the nature of jointly administered flow constraints, guidelines as prescribed are highly infeasible and will lead to extensive guideline violations over time. Under the most restrictive scenario examined, average volume is overestimated by 20%, and value, by 37%, over the adjacency unconstrained model. Further, nearly one-fourth of the forest area will need to be left unmanaged to maintain adjacency and flow restrictions under the most restrictive scenario, which is a result of the biophysical nature of the system examined. Finally, the opportunity cost of adjacency restrictions is shown to be an increasing function of the restrictiveness of various flow constraints, ranging from $2587 to $7085 per adjacency violation avoided.
