Science Framework forEcosystem-Based Management

Objective: Define general strategy for an ecosystem approach to management focusing on diverse ecosystem services,
societal preferences, and associated tradeoffs

Illustrate with real world example(s)
The Problem
Societal preferences imperfectly known
-- Specify Utility Functions
Ecosystem processes incompletely known
Data/Model limitations for some or all components
-- Adopt risk assessment framework
-- Adopt broad definition of model







Approach
Identify Key Ecosystem Services
Define Objectives for Management unit
Specify Relationships among Services, State Variables, Drivers, and Control Variables

-- Dynamical Models
-- Static Models
-- Empirical Predictors
-- Indicators

Evaluate Policy Options

Define Objectives for Management
Ecosystem Services
Locally Caught Seafood (commercial)
Sport Fishing
Ecotourism
Diving
Shoreline Protection / Water Quality
Drivers
Shoreline Development
Demand for Local Seafood
Tourist Demand
Diver Demand
Recreational Demand
