2. Wetlands are defined as lands
transitional between terrestrial and
aquatic systems, where the water
table is usually at or near the surface
or the land is covered by shallow
water.
“areas of marsh, fen, peatland or
water, whether natural or
artificial, permanent or
temporary, with water that is static
or flowing, fresh, brackish or
salt, including areas of marine water
the depth of which at low tide does
not exceed six metres.(According to
“Ramsar Convention ”.

3. Lake Ahiron, locally known as Chand
Beel is located at the Northern side of
Murshidabad district. It is situated just
at the South - Eastern side of National
Highway-34.
It is extended in North from 24 30 to
South 24 26 50 latitudes and East 88 02
to West 87 58 48 longitudes. This is
situated 55 km north to Berhampur.

IMPORTANT OF WETLAND
Wetlands are one
of the most
productive
habitats in the
world. Different
kinds of wetlands
play different
important roles.
These are :
Water
Quality
Wildlife
Habitat

5. 1.Conservation of the Wetland flora and fauna.
2.Prevention of biotic interference to the habitat.
3.Prevent water pollution of the lake by strengthening
conservancy measures around it .
4.Maintain water quality and hydrological balance and
sediment fluxes.

6. The flora of the lake consists mainly of Water hyacinth .Many
algae and pteridophytes like AzollaPinnata (water fern) and
Marsillea quadrifolia.L(shusni) is common ,these are free-
floating and the rest is found commonly in the edges of the
water bodies.

8. Generally some portions of the wetlands are Vested and owened by Fishery
Department of Government of West Bengal and fishing right is given to the
cooperative society.
This wetland use mainly :
Pisciculture
Irrigating nearby agricultural field
Navigation
Jute retting
Domestic purpose.

9. 1.Increasing population and rapidly developing agricultural
economy .Result is that water bodies leading to its loss.
2.The main reason behind it is that most of the part of wetland
is effected by high or medium rate of siltation.
3.This in tern leads to gradual conversion of wetland into
agricultural land.
4.More over all the water bodies are effected by pollution.

10. In view of the fact several steps has been taken by the Govt. for
conservation , up gradation and improvement of the pattern of
utilization of the water resources from the existing water bodies.
They are :
1.Dedging to remove siltation.
2.Digging and financial assistance and fishing in the bil.
3.To stop pollution at source , sewage treatment ponds are dug near
the wetland to treat polluted water.
4.Modern technologies are also used for fishing like improve fish
feeding ,water quality management etc.
5.Bleaching and cleaning the wet land with lime ,potassium
permanganate and organic matter like cow dung are used to improve
water quality.

11. Wetlands are most productive ecosystem on earth exhibiting a
great diversity in both floral and faunal distribution. They play
certain vital function in maintaining environmental
sustainability. So full implication of wetland values and losses
are to be undertaken in perspective of attempt for its
conservation and management for sustainable use of its
resources by Government and non Government organization.
