INTRODUCTION

Wetlands are defined as lands transitional

between terrestrial and aquatic eco-systems where the

water table is usually at or near the surface or the land is

covered by shallow water (Mitsch & Gosselink 1986).

The various reservoirs, shallow ponds and numerous

tanks support wetland biodiversity and add to the

country’s wetland wealth. It is estimated that freshwater

wetlands alone support 10 percent of the known range of

biodiversity in India (Deepa & Ramachandra 1999)

including 2400 birds species and sub species of birds.

Wetlands in India occupy 58.1 million hectares,

including areas under wet paddy cultivation

(Prasad et al., 2002)

Wetlands and waterbirds are inseparable

elements and support a rich array of waterbird

communities (Grimmett and Inskipp, 2007). Waterbirds

are an important component of most of the wetland

ecosystem as they occupy several trophic levels in the

food web of wetland nutrient cycles. Activities of

waterbirds are considered as indicator of quality of the

wetland ecosystem and form the terminal links in many

aquatic food chains, and as a result they reflect changes

originating in several different ecosystem components

(Custer and Osborne, 1977). Parish and Prentice (1989),

suggested various direct and indirect factors that causes

deterioration of wetlands all over the world. Factors that

cause wetland deterioration like vegetation changes,

deterioration of water quality, siltation, cattle grazing and

poaching were recorded in India by Vijayan (1986),

Anjaneyulu (1991), Sampath (1993) and Trisal (l993).

No in-depth study of ecology of wetlands as

birds habitat has been conducted in Madhya Pradesh.

Some sporadic references are available that too limited

to check listing of birds. Wetland ecology has been

studied in isolation lacking avian ecology. Barna wetland

of Madhya Pradesh is an identified wetland under

National Wetland Conservation Programme by Ministry

of Environment and Forests (Govt. of India). No detailed

study has been conducted on the water birds of the Barna

reservoir, but a preliminary survey in the winter of

2001- 2002 revealed a huge congregation of more than

20,000 birds on the main water body

(Islam & Rahmani, 2004). This site has not been covered

during the Asian Waterfowl Census, and needs regular

monitoring of water birds.

MATERIALS AND METHODS

Barna is one of the major irrigation projects of

Madhya Pradesh constructed by damming river Barna in

Raisen district near Bari village. This is located about

100 kms from Bhopal. Narmada basin is located at the

latitude 22°50’ 13.5” N and longitude 77°50’ 78.10” E.

This reservoir is an important source of fish production

in the area. Regular fish stoking is done in this reservoir

every year. The water of the reservoir is mainly used for

the fisheries and irrigation purpose. The reservoir

supports a rich biodiversity and provide habitat for

wildlife including migratory birds. A major part of the

reservoir basin falls under Singhori Wild Life Sanctuary.

Wetland habitats:

Study of avifaunal diversity of Barna wetland

was conducted between March, 2009 and February,

2011. Seasonal observations were made during the study

but they were clubbed into four observations for further

analysis. Birds were observed within the transect of

300m. Nikon Binoculars of 10×50 were used for

observations. The field book of Ali and Ripley (1986),

Ali (1996) were used to identify bird species. The

checklist was prepared using the standardized common

and scientific names of the birds of the Indian

subcontinent by Manakkadan and Pittie (2001).

Data analysis:

The statistical analysis was carried out using

software Paleontological Statics (PAST) version 2.04

(Hammer et al., 2001) to find out the significance of

spatial variation on biological parameters. Margalef’s

species richness (d), Shannon-Wiener diversity (H’) and

Balapure et al., 2012

461 Journal of Research in Biology (2012) 2(5): 460-468

Page 3: Avian diversity in Barna Wetland of Narmada basin in Central India

Simpsons index (D) was calculated. Jaccard’s similarity

cluster was constructed based on bird species richness.

RESULTS AND DISCUSSION:

In the present study 63 bird species were

recorded from Barna reservoir belonging to 12 families

and seven orders (Table: 1). Das and Saikia 2011

recorded 39 species of water birds from 16 different

families from Deepor beel (Ramsar site) of Assam.

Family Anatidae was found to be the most dominant

family represented by 16 species followed by Ardeidae

with nine species and Charadriidae with eight species

(Fig:1). Family Recurvirostridae had only one species

Himantopus himantopus commonly known as Black

winged stilt. Rathore and Sharma (1999) also reported

Anatidae to be dominating family with 11 species in

Sarsai Nawar in UP. Surana (2007) recorded Anatidae to

be most dominant family with 11 species, Ardeidae with

nine species and Charadriidae with eight species in

Chimdi lake of Nepal. Tak et al., (2010) reported 31

water birds from Hathnikund wetland of Haryana with

maximum richness of Anatidae (35%) followed by

Ardeidae (19.6%). Rajashekara and Venkatesha (2011)

recorded Ardeidae to be the most dominating family

having nine species followed by Anatidae family having

five species from Bangalore lake.

Site-1, Site-4 and Site-7 harbored maximum bird

species richness compared to the other sites. The

Page 4: Avian diversity in Barna Wetland of Narmada basin in Central India

maximum diversity of water birds was noted at Site-4 as

47 species followed by Site-7 having 45 bird species,

Site-1 with 31 species (Fig:2). These sites were

characterized as shallower zones of the reservoir.

Minimum water bird assemblage was noted at Site-8,

Site-9 and Site-2. Family Anatidae, Phalacrocoracidae,

Rallidae and Alcedinidae were the abundant families of

Barna reservoir which were observed at all the sites

comprised of both shallower zone as well as deeper zone.

Family Ardeidae, Ciconiidae, Threskiornithidae,

Gruidae, Recurvirostridae, Charadriidae and Laridae

were restricted only in shallower zone of the reservoir.

Kurup (1991) attributed it to the larger mudflat areas

which attract shorebirds in large numbers. Cormorants

were noted both in shallow and deeper zone of the

reservoir. Waders were restricted to only shallow waters

having a depth of 2 mt. Deep water has been reported to

reduce the availability and accessibility of invertebrates

to feeding waders (Murkin and Kadlec, 1986).

Murkin et al., (1997) found that diving ducks as a group

selected habitat that consisted of deeper water and less

vegetation.

There was a temporal variation in bird diversity

(Fig:3). The maximum diversity of birds was noted in

winter season. Similar observation was noted by

Rajashekara and Venkatesha (2011) in 15 major lakes of

Bangalore during 2008. Chinchkhede and Kedar (2012)

reported 76 species belonging to 15 orders in and around

Koradi lake of Nagpur among which 54 species were

recorded as resident; 09 species as seasonal local migrant

and 13 species as winter migrant. There was a gradual

decline in species richness in the reservoir as the weather

condition changes from colder to warmer. A sharp

decline was recorded during summer 35 species of water

birds in the reservoir belonging to 12 families and 7

orders. With the onset of monsoon in June and July, the

field conditions are unsuitable for birds and the bird

occurrence was significantly low in all the study areas.

The diversity of birds vary according to the weather

conditions like rainfall, temperature, relative humidity

and precipitation changes have a profound effect on

water level, cover ratio and the quality of the habitat for

the water birds (Rao et al., 1997). Anatidae family which

was the most dominant family during winter period was

represented by sixteen species. This indicates that most

of the wintering water birds belong to Anatidae family.

Vyas et al., (2010) observed that Anatidae was the most

dominating family in Bhoj wetland. The second most

dominating family was Charadriidae represented by 10

species followed by Ardeidae represented by nine

species. Vijayan (1988) while working on Bharatpur

wetland also recorded similar observations. Members of

Anatidae family were found to dominate among the

winter migratory birds. Coot was the only dominant

migratory bird belonging to family Rallidae which could

not be recorded after Monsoon season in Barna reservoir.

Family Ardeidae comprised of Egrets and herons showed

an increasing population trend from the beginning of the

summer season. Vijayan (1987, 1988) recorded increase

in egret’s population during monsoon period due to their

breeding season.

The various diversity indices for water birds are

shown in Figure 4. The higher value for Shannon’s index

was observed at Site-4 (2.554) followed by Site-5 (2.4).

Simpson’s diversity index was highest at Site-6 followed

by Site-5 and Site-4. Species richness was highest at

Site-4 (6.14), followed by Site-7 (5.87) and Site-1 5.05).

Lowest species richness was recorded at Site-3, Site-6

and Site-9 having a depth of 4-6 mt.

The dendogram constructed showed the

similarity of the sites according to the species richness of

the water birds present at nine sites of Barna reservoir

(Fig: 5). Two main clusters were formed; first cluster

was formed with Site-1, Site-4 and Site-7. Among the

first cluster Site-4 and Site-7 forms a subgroup. These

two sites exhibit maximum species diversity as compared

to the other sites having shallow depth (0-2 mt) with rich

marophytic vegetation which serves food for water

birds. According to Mitchell & Prepas (1990) and

Clifford (1991) shallow lakes with broad littoral zones

and abundant macrophytes and macroinvertebrates

provide excellent habitat for aquatic birds. Second

cluster was formed with Site-2, Site-3, Site-5, Site-6,

Site-8 and Site-9. In the second cluster, Sites 6 & 9

formed sub cluster because of low richness of bird

species may be due to their similar depth profile. These

sites come under deeper zone having a depth of 4-6

meters. Maximum depth was the another morphometric

feature that showed strong correlations with guild

composition and richness of water birds (Paszkowski and

Tonn, 2006).

CONCLUSION:

It is revealed that overall, 63 species belonging to

12 families and 7 orders were documented which

included 36% residents, 35% local migrants and 29% as

migratory species. Among these 24.5% were considered

to be common, 23.81% fairly common, 31.75%

uncommon and 19.05 % rare species. From the present

study it was revealed that existence of various patterns of

spatial and temporal segregation among the water bird

reflected the different requirements that are met by these

limnologically variables. Higher values of Shannon’s and

Margalef indices indicated rich water bird occurrence

and species richness at Site 1, Site 4 and Site 7. Water

bird abundance status was calculated according to Kumar

& Gupta (2009). Sarus Crane which was declared as

vulnerable species in Important Bird areas of India

(Islam & Rahmani, 2004) recorded with a total

number of 25 from the shoreline of the wetland. Three

near t hreat ened spec ies name ly Dar t er

( A nh inga me lano ga s t e r) , P a int e d S to r k

(Mycteria leucocephala) and Oriental white Ibis

(Threskiornis melanocephalus). We have recorded nearly

57 Darter, 53 Painted stork and 12 Oriental white Ibis

during the entire study period from the wetland.

Conservation of this wetland is very essential to sustain

migratory bird populations along with the threatened and

vulnerable birds of that area.
