1 An Overview

2 EDT – Habitat Model Results = Species Habitat Potential Raw Data and Observations Species-Neutral Environment Species-Life Stage View of Environment

3 Equilibrium Abundance Recruits/Spawner (Density Dependent Productivity) Recruits (returning adults/spawner) Spawners (number in first generation) Habitat Capacity Habitat (Density Independent) Productivity

4 EGGS JUVENILES SMOLTS SUBADULTS SPAWNING ADULTS

5 VSP-Relevant Parameters Habitat Capacity LS/Pop. Productivity Equilibrium Abundance Diversity Survival (limiting) factors Life History Information Used Here Need to Think Broadly About Historical Potential!! Model Habitat Environment Species/Habitat Rules Habitat Potential Habitat Potential Trajectory Generator

6  Reference scenario maximum potential  Difference restoration potential  Model for potential life history expression Reference Condition (Ideal) Patient Template Current or Future Condition (Degraded)

7  Trajectories = range of life history expression  Different pathways have different survival rates  Survival (limiting) factor effect on LS productivity  Combined success rate = habitat productivity  % successful = diversity index

8  Life history information used to parameterize EDT trajectory generator  Emphasize both existing AND potential life history diversity  Don’t be too literal! Need to represent potential diversity (not just what exists today)  EDT selects successful trajectories
