Answer: 5 years

The 2008 Compensatory Mitigation Rule generally requires a minimum of 5 years of monitoring for compensatory mitigation sites.

Which of the following is a performance standard commonly used to evaluate mitigation site success?

Answer: Percent cover of planted native vegetation

Percent cover of planted native vegetation is a standard performance metric used to assess whether mitigation plantings are establishing successfully.

What may happen to a mitigation bank's credits if it fails to meet performance standards?

Answer: Credits may be withheld, suspended, or the bank closed by the Corps

What is 'temporal loss' in wetland mitigation?

Answer: The time lag between wetland impact and when mitigation achieves equivalent function

Temporal loss refers to the ecological loss occurring during the gap between when a wetland is impacted and when compensatory mitigation achieves equivalent functional value.

Which document must a permittee submit to demonstrate how compensatory mitigation will achieve no net loss?

Answer: Compensatory Mitigation Plan

A Compensatory Mitigation Plan must detail the objectives, site selection, design, management, monitoring, and performance standards for all mitigation activities.

Which of the following represents a common cause of compensatory mitigation site failure?

Answer: Improper hydrology or inadequate water supply

Improper hydrology is one of the most common causes of mitigation failure because wetland vegetation cannot establish without adequate and appropriate inundation or saturation.
