CFP Ecosystem Restoration 2

Question 1

Which technique is most effective for restoring riparian vegetation to stabilize stream banks and reduce sediment input?

Accepted Answer

Live staking with native willows and dogwoods

Answer

Live staking with native willows and dogwoods establishes root systems that stabilize banks and provide fish habitat structure.

Question 2

What is the primary goal of large wood (LW) placement in stream restoration?

Accepted Answer

Create hydraulic complexity, pools, and cover for fish

Answer

Large wood placement increases hydraulic complexity, forming pools and cover that enhance fish habitat.

Question 3

Nutrient spiraling length in a stream decreases when restoration efforts successfully increase:

Accepted Answer

Biotic uptake and retention capacity

Answer

Shorter nutrient spiraling lengths indicate higher biotic uptake and retention, reflecting improved ecosystem function.

Question 4

Which metric best indicates successful macroinvertebrate community recovery following restoration of a degraded stream?

Accepted Answer

Increase in EPT (Ephemeroptera, Plecoptera, Trichoptera) taxa richness

Answer

EPT taxa are pollution-sensitive indicators; their return signals improved water quality and habitat conditions.

Question 5

When reconnecting floodplains to their river channel, the primary ecological benefit for fish is:

Accepted Answer

Access to floodplain nursery habitat and food resources

Answer

Floodplain reconnection provides fish with spawning and nursery habitat and increases allochthonous food inputs.
