Question 1

Which federal law provides the primary legal framework for wetland restoration projects requiring dredge-and-fill activities in the United States?

Accepted Answer

Clean Water Act Section 404

Answer

Section 404 of the Clean Water Act regulates the discharge of dredged or fill material into waters of the US, which governs most wetland restoration construction activities.

Question 2

In prairie restoration, the practice of 'plug planting' is best described as:

Accepted Answer

Transplanting small rooted plant starts into prepared substrate

Answer

Plug planting involves transplanting small rooted native plants (plugs) into restoration sites to establish vegetation faster than direct seeding alone.

Question 3

What term describes the minimum viable population (MVP) threshold concept in restoration ecology?

Accepted Answer

The smallest population with a 95% chance of persisting for 100 years

Answer

MVP is typically defined as the smallest isolated population having a 95% (or similar) probability of survival for 100 years despite stochastic events.

Question 4

A restoration planner is designing a riparian buffer. Which factor most directly determines the appropriate buffer width to achieve water quality protection?

Accepted Answer

Adjacent land use and pollutant loading

Answer

Buffer width requirements are primarily driven by the type and intensity of adjacent land uses and the corresponding pollutant loads the buffer must intercept.

Question 5

The 'reference site' approach in restoration ecology is used primarily to:

Accepted Answer

Define target conditions and success metrics for a restoration project

Answer

Reference sites represent relatively undisturbed examples of the target ecosystem type and are used to set measurable ecological goals for restoration.
