Human impacts on natural ecosystems Challenges for natural resource managers
responsible for protecting and restoring natural systems► Chesapeake Bay – Degraded waters► Louisiana – Receding coastlines► Florida Everglades – Altered hydrology, increased
nutrients Restoration programs need the integration of
science and policy to establish agreement on restoration objectives

Non-quantitative planning tools that identify: ► Major anthropogenic drivers and stressors
on natural systems► Ecological effects ► Best biological indicators (attributes)
Provide a logical process for synthesizing, organizing, and prioritizingexisting ecological knowledge

Conceptual Ecological Models Facilitate the formulation of hypotheses describing not only what
system attributes are important but why changes occur
Provide the framework for creating performance measures

BUILDING STRONG®BUILDING STRONG®
Hypothesis Clusters Subject-specific conceptual ecological
models Address the integration of stressor-
response relationships of the system Provide refinement in types and
numbers of performance measures and metrics► Linked to monitoring components
Identify monitoring/research needs and plan the design of restoration programs
