INTRODUCTION

“Kulik” bird Sanctuary or alternately known as the Raiganj bird Sanctuary is situated 4 km North

from the center of the Raiganj town, the district head quarter of Uttar Dinajpur district. The

geographical boundary of the Sanctuary is 25º 39′ N to 25 º 40′ N latitude and 88º 7′ E to 88º 8′

E longitude. Sanctuary is covering an area of 1.30sq. km, of which 0.14 km is the core area and

remaining 1.16 sq. km is the buffer zone. ‘Kulik’ river flows around the part of the sanctuary

and acts as a natural boundary in its eastern and south eastern part, the national highway NH –

34 provided the western boundary of the sanctuary.

This sanctuary was declare in the year 1985, as a Wild Life Sanctuary but its development

begins in 1970, by the Department of Forests, Govt. of West Bengal, as a part of the Social

Forestry Programme. Forest department has planted a number of trees in this area specially

those tree species Suitable for the growth in the tropical dry deciduous forest region.

As the part of the development programme many water bodies have been created in this area.

The river Kulik and these water bodies attracts various migratory birds in this area like the Open

Bill Stock, Night Heron, Cormorant, Little Cormorant, Egrets, etc. from South East Asian

Countries and from the coastal areas. In totality about 70,000 to 80,000 birds species belong to

164 species are gathered here every year (Mitra, 2003).

Climatic condition of the Sanctuary is Sub-tropical. During the summer the temperature

reaches up to 42º C and it observed a very cool winter with an minimum temperature of 6º C.

This area received an average annual rain fall of 550mm (Mitra, l.c.).

This Sanctuary, in the Year 2011 has been declared as the Nature Interpretation Center.

Exotic species are those, which are found to grow, outside of their normal native habitat. If any

exotic species found to grow outside their natural adapted ranges and acquired dispersal

potential, those are regarded as the Exotic Alien Species. According to the IUCN when an alien

species, which become established in new natural or semi natural ecosystem or habitat and

create threats to native biological diversity are regarded as the Alien Invasive Species.

Convention for Biological Diversity 1992 visualize “Biological invasion of the alien species as the

second worst threats after the habitat destruction”. So, biological invasions may be considered

as a form of biological pollution.

Invasive species causes loss of the biodiversity including species extinction, changes of the

hydrology & pedology and the ecosystems function. Besides these, many alien invasive species

supports our farming, agriculture and forestry system in bulk.

Thus the exotic alien species are consider now a days as a serious hindrance for conservation

and sustainable use of the Biodiversity in one hand and by the other hand it become a tools for

the development.

Biological invasion now-a-days operated on global level and it will undergoes rapid increase due

to increasing globalization of the markets, rise in global trade, travel and tourism.

Naturalization of an exotic species has been recognized as the first phase of the biological

invasion. According to Richardson (2000) a naturalized species is an introduced nonnative

exotic alien species that can consistently reproduce and sustain population over many

generations without direct intervention by humans. After successful local establishment, some

naturalized species disperse and produce viable offspring in the areas distinct from their site of

introduction; such naturalized species are called as the Invasive alien species.

Therefore, it is very important to make an effective implication management of invasive

species, knowledge about their diversity, life forms habitat, etc. In Kulik bird sanctuary of Uttar

Dinajpur district, about 80,000 birds are reach every year and these birds are can be regarded

as the place of plant introduction (Mitra, l.c.).

On the basis of the above mentioned points the present work has been undertaken to study the

exotic species of “Kulik” bird sanctuary.

LITERATURE SURVEY:

Voight (1845) was the first botanist who had made an attempt to enlisted the exotic plants of

the Shibpore and Serampore Botanical garden in his famous enumeration “Hortus Suburban

Calcuttensis”. Then Bruhl (1908) studied the exotic plants of the then Bengal province, in

conformity by the work of the Prain (1903a, 1903b, 1905), Van Rheede (1678 - 1703), Roxburgh

(1814, 1820, 1824), J. D. Hooker (1872 - 1897), Biswas (1934a, 1934b), etc.

After independence a lot of change took place in the geographical and political boundary of the

then Bengal province. In this newly born state West Bengal several work on the exotic plants of

the state have been carried out by different workers like – Clushaw (1950), Datta (1954),

Chakravarty (1957), Pal & Bhattacharya (1959), Chatterjee (1960), Datta & Maiti (1962),

Mahapatra et al.(1965), Bennet (1965, 1966), Banerjee & Pal (1970), Maiti & Hore (1978), Basak

(1979), Maiti & Guha Bakshi (1981), etc. Besides these Bennet (1974), Sanyal (1994), Guha

Bakshi (1984), studied the flora of different districts like Howrah, Bankura and Murshidabad

respectively. Bhattacharya (1997) in the introductory essay of the flora of West Bengal (Vol. - I)

give a precise note on the exotic flora of West Bengal. Recently Mitra & Mukherjee (2012)

published the entire floristic composition of the district West Dinajpur including the present

Uttar & Dakshin Dinajpur, but still there is not a single publication which deals with the exotic

flora of the district, so, this present work has been taken into account to enumerate the exotic

plants of this sanctuary.

MATERIAL & METHODS:

This present study is entirely based on the field exploration as well as on the basis of the

perusal of the literature. In this present enumeration all the exotic species are arranged

alphabetically in the table below with their family, habit & habitat, phonological data, nativity,

time of introduction in the country as well as in the state, mode of introduction, and present

status.

In this present list some plants are marked with the asterisk (*) to indicate that these plants are

not dealt within the Floristic account of the district by Mitra & Mukherjee (2012).

RESULT & DISCUSSION:-

From the enumeration (Table - I) it has been clearly understood that this sanctuary harbor a

handsome amount of the exotic flora.

Table- I. Diversity of the exotic aqngiospermic taxa of Kulik Bird Sanctuary

There are 92 species of exotic plants belongs to 73 genera under 37 families. Of these 37

families 33 belongs to the class Magnoliopsida and 4 belongs to the class Liliopsida, (Table – II).

From the above table – I, it becomes clear to us that on the basis of the number of genera and

species Asteraceae and Poaceae occupied the first and second position respectively. List of the

5 – dominant familes based on the numbers of genera and soecies are given in the table – II

Regarding the nativity of the exotic floristic elements recorded from this sanctuary it has been

observed that the new world elements belong to the country North America, South America,

Mexico, Tropical America, and West Indies etc. are top of the list consists of 58 species (63%)

out of the total collected 92 species of the exotic species followed by the African Element which

are 9 (9.78%), Malayan Element (Including the SriLanka, Malaya & Australia) – 9 (9.78%), Sinu –

Japanese element (including the Chinese, Japanese and Mayanmer element) – 7 (7.60%), and

European element - 7 (7.60%), a detailed conspectus of the nativity of the exotic elements is

given in the figure – II below.

It is very interesting to note that, out of the 92 species 56 species (60.86%) are introduced

unintentionally as weed, 30 species (32.61%) as Ornamental plants and 6 species (6.52%) as the

food plants.
