1. What is the primary goal of wetlands restoration?
A. Increase recreational land use
B. Restore natural hydrology, vegetation, and functions
C. Eliminate standing water
D. Convert wetlands to agricultural use
Answer: B
Rationale: Wetlands restoration focuses on reestablishing natural
hydrology, native vegetation, and ecological functions.
2. Which hydrologic condition is most critical for defining a wetland?
A. High salinity
B. Prolonged soil saturation or inundation
C. Steep slopes
D. High elevation
Answer: B
Rationale: Wetlands are defined by soils that are saturated or
inundated long enough to support hydrophytic vegetation.
3. Hydric soils are best described as soils that are:
A. Rich in sand
B. Permanently frozen
C. Saturated, flooded, or ponded long enough to develop
anaerobic conditions
D. Always dry
, Answer: C
Rationale: Hydric soils form under anaerobic conditions caused by
prolonged saturation.
4. Which plant type is most commonly associated with wetlands?
A. Xerophytes
B. Hydrophytes
C. Mesophytes
D. Epiphytes
Answer: B
Rationale: Hydrophytes are plants adapted to growing in water or
saturated soils.
5. A key indicator of wetland hydrology is:
A. Soil compaction
B. Presence of upland grasses
C. Water-stained leaves or drift lines
D. High soil pH
Answer: C
Rationale: Physical evidence such as drift lines and water marks
indicate periodic inundation.
6. Which federal regulation in the United States most directly
governs wetlands protection and restoration?
A. Clean Water Act Section 404
B. Safe Drinking Water Act
C. Resource Conservation and Recovery Act
D. Endangered Species Act only

condition for restoration.
8. Which activity most commonly causes wetland degradation?
A. Natural flooding
B. Drainage and filling

D. Wildlife grazing
Answer: B
Rationale: Draining and filling disrupt hydrology and destroy
wetland functions.
9. What is a mitigation wetland?
A. A naturally occurring wetland
B. A wetland created to offset permitted impacts
C. A wetland used for recreation
D. A wetland with no regulatory oversight
Answer: B
Rationale: Mitigation wetlands compensate for unavoidable
