How many pairs given above are correctly matched?

(a) Only one pair

(b) Only two pairs

(d) All four pairs

2. Ans: b

Explanation:

All the four wetlands are designated as Ramsar sites as wetland of international significance.

It is located at the northwest Himalayan biogeographic province of Kashmir, back of Pir Panchal.
It is a natural perennial wetland contiguous to the Jhelum basin. It is the only site with remaining reedbeds of Kashmir.
It is pathway of 68 waterfowl species like endangered White-eyed Pochard, coming from Siberia, China, Central Asia, and Northern Europe. It is also an important source of food, spawning ground and nursery for fishes.
Typical marshy vegetation complexes inhabit this lake.

Also known as Rudijala, it is a lowland sedimentation reservoir in the northeast hills, fed by three perennial streams (Noacherra, Durlavnaraya cherra, Kemtali cherra) discharging to the River Gomti (not to be confused with River Gomati of Ganga Basin).
The lake is an ideal habitat for IUCN Redlisted Three-striped Roof Turtle- Kachuga dhongka.
Owing to high rainfall (2500mm) and downstream topography, the wetland is regularly flooded with 4-5 times annual peak, assisting in groundwater recharge.

It is the largest freshwater lake in Kerala.
It is spring-fed and the source of drinking water for half a million people in the Kollam district.
The water contains no common salts or other minerals and supports no water plants; a larva called “cavaborus” abounds and eliminates bacteria in the water, thus contributing to its exceptional purity.

It is a natural wetland with freshwater springs and inland subterranean karst formations.
Renuka is oblong shaped wetland flanked by two parallel steep hills running east-west. It is shaped like a sleeping women.
Renuka wetland is a perennial water body fed by 21 seasonal streams which are vigorous particularly during the monsoon season. Internal springs of the wetland are the perennial source of water.
The underground network of channels in the Limestone and Dolomite formations of the area are possibly conduit to discharge groundwater to the wetland.
The climate of the area is of sub-tropical monsoonic type. The average precipitation at Renuka wetland area is 150-199.
The soil composition of the region also show a heterogeneous mixture of carbonate rocks, sandstones, shales, siltstone in various proportion. The soil cover is thin due to weatheringl-limited conditions.
The wetland is covered with vegetation of sub-tropical forest comprises of Chhal, Sain, Bahera, Harar, Kachnar, Tun, Shisham and Amaltas etc. Natural Sal forest exists in the northern side of the wetland.

Hence, option b is correct.
