Ecosystem Restoration in the Corps Purpose: “…to restore degraded significant
ecosystem function, structure, and dynamic processes to a less degraded, more natural condition.” ER 1105-2-100 Section E-30
Intent: “…to partially or fully reestablish the attributes of a naturalistic, functioning, and self-regulating system.” ER 1165-2-501 Sec 6
Scope: Nationally and regionally significant wetlands, riparian and other floodplain and aquatic systems OASA Memo 29 July 05; CECW-PB Memorandum 15 March 07

Structure and FunctionStructure: The characteristic structure of an
ecosystem is obtained by the systematic physical organization of the abiotic and biotic components of that particular ecosystem.
Function: The characteristic exchanges of material, energy and nutrients within an ecosystem are called ecosystem functions. The specific ecosystem functions that are apparently beneficial to human civilization are called ecosystem services.

Competition for Restoration Funds
President's FY10 Budget - $546M for aquatic ecosystem restoration
Top 5 projects were: Everglades/South FL Eco Rest (Construction) - $214M Columbia R Fish Mitigation (Construction) - $96M Missouri River Recovery (Construction) - $70M Louisiana Coastal Area (Investigations) - $25M Upper Mississippi River Restoration (Construction) - $20M
These 5 projects total $425 or 78% of the President's FY10 Budget for aquatic ecosystem restoration.

Resource Significance
Significance is defined by institutional, public, and technical considerations
Reflects an effort to measure the value of ecological functions to the nation.
Constitutes a budget decision factor for non-monetary outputs
Determinations of significance need to be clearly described
Significant resources relate to problems, opportunities, objectives and constraints and most importantly federal interest

Evaluate Alternatives
Evaluation process focuses on quantitative and qualitative restoration outputs
Units that measure an increase in "ecosystem" value and productivity are preferred ER1105-2-100 Section 3-5 c.
“habitat-based evaluation methodologies … shall be used to the extent possible to describe and evaluate ecological resources and impacts” ER 1105-2-100 Section C-3

Evaluate Alternatives
Two minimum categories – cost and outputs
May have multiple output categories At least one “Output category that
reasonably represents ecosystem restoration benefits”

Evaluation Tasks
1 – Forecast most likely with project condition for each alternative
2 – Compare with-project to the without project condition
3 – Characterize beneficial and adverse effects by:► magnitude, ► location, ► timing and ► duration
