Question

Arrange the following zones in riparian forest (from agricultural site to river side) :
A. Crop land
B. Wildlife habitat
C. Aquatic habitat
D. Filter agricultural run off
E. Bank stability
Choose the correct answer from the options given below :

• A. A - D - B - E - C
• B. A - E - B - D - C
• C. C - A - B - E - D
• D. C - B - A - E - D

Hint:

Riparian Buffer Transect:
Crop Field $\rightarrow$ Grass Filter Strip (Zone 3) $\rightarrow$ Maged Forest Wildlife (Zone 2) $\rightarrow$ Bank Root Stabilization (Zone 1) $\rightarrow$ Water Body.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question requires arranging the functiol buffer zones of a standard three-zone Riparian Forest Buffer in spatial order starting from the upland agricultural field boundary down to the open river water channel.

Step 2: Zotion Model of Riparian Buffers (USDA Standard):
\begin{enumerate
• Upland Source Area [A]: Crop land active agricultural field where agrochemicals and sediment runoff origite.
• Zone 3 (Runoff Filter Zone) [D]: Outer grass filter strip adjacent to crop land designed to slow surface runoff, settle suspended soil solids, and filter nutrients.
• Zone 2 (Maged Forest Wildlife Habitat) [B]: Middle zone consisting of fast-growing trees/shrubs that provide wildlife habitat corridors and sequester subsoil nitrates.
• Zone 1 (Stream Bank Stability Zone) [E]: Inner forest strip immediately bordering the river channel where mature deep tree roots anchor stream banks against water erosion.
• Aquatic System [C]: Open stream/river channel supporting aquatic life.

Step 3: Detailed Explation:

• Tracing the transect from field to stream: Crop land (A) $\rightarrow$ Filter runoff (D) $\rightarrow$ Wildlife habitat (B) $\rightarrow$ Bank stability (E) $\rightarrow$ Aquatic habitat (C)
• This creates the exact spatial arrangement: A - D - B - E - C.
• This matches option (A).

Step 4: Fil Answer:
The correct spatial sequence from agricultural site to river side is A - D - B - E - C, corresponding to option (A).
