Design Principles 1) produce maximum benefit with the most efficient combination of resources. (universal)
Restoration Costs Landscape to Landscape Variation in Beginning Condition Population Goal Cost Cost Beginning Condition Bird Population Beginning Condition Landscape 1 Landscape 2
Attaining vs Sustaining Goals Maintenance Costs Landscape Equilibrium
Maintenance Costs Landscape Equilibrium Maintenance Costs Attaining vs Sustaining Goals
Attaining vs Sustaining Goals Restoration Cost Long term Maintenance Costs
Design Principles 1) produce maximum benefit with the most efficient combination of resources. 2) consider both restoration and long-term maintenance costs.

Protecting Land for Bald Eagles in the lower Chesapeake Bay What is our objective (goal)? Protect land for 120 pairs What management tools should we use? Acquisition What resources are available to us? To be determined What criteria are we going to use to evaluate strategy? Maximize benefit, minimize cost
