INTRODUCTION
The Wandur National Park comprises about 12 islands and is located about
30 km southwest of Port Blair. the capital city of Andaman and Nicobar
Islands. Comprising of 300 islands, this archipelago is amongst the most
far-flung regions of India. Labyrinthine Island groups as they are aptly
named because of the channels weaving around and forming a maze. they
are home to India. s best marine parks.
Most of the islands in the park are densely forested; the open spaces
are covered with scrub and creepers. A casual glance around and one can
spot brilliant tropical flowers including orchids, broken branches and
fallen leaves spread over the jungle pathways. One can also hear the
bird calls, but unless in the open, it is difficult to spot the terns,
gulls, ospreys, serpent crested eagles, wood pigeons and of course the
swifts.
Caves and caverns are another interesting aspect of these islands since
most of them are quite rocky. The sandy beaches where the boats can land
are interspersed amongst the sheer granite cliffs and walls of the
islands.
But the most striking feature of all these islands is the vegetation.
Very dense, it comes right down to the shore, seeming to merge into the
sea. Branches and creepers overhang and dip into the seawater.
LOCATION
Wandur or Marine
National Park is located in the Union Territory of Andaman & Nicobar at
a distance of around 30 km from Port Blair, capital of this centrally
administrative division of India. The park extends from the latitudes
10°13'. 14°N and the longitudes 92°. 93°E, in the Bay of Bengal.
CLIMATE
Wandur National Park
has a tropical climate. There is medium to heavy rain from May to mid
September and November to mid December. There is no extreme climate
except rains and tropical storms in late summer, which causes heavy
damage.
FLORA AND FAUNA
These island beaches
are great nestling place for growth of Leatherback (Dermochelys
coriacea), Hawksbill (Eretmochelys imbricata), Olive Ridley (Lepidochelys
olivacea) and Green Turtles (Chelonia mydas). Several hundred
Estuarine Crocodiles (Crocodylus porosus) can also be found here
in densities inversely proportional to human populations. The Coconut
Crab (Birgus latro) on the other hand is an important species
found mostly on the South Sentinel Island. The Roseate Tern (Sterna
dougallii) and Black-naped Tern (Sterna sumatrana) nest on
the islands in unknown numbers, the Sooty Tern (Sterna fuscata)
also breeds here. Molluscus, particularly Tridacna, are also important
reef builders.
There are extensive mangrove stands around many islands although many of
these have been destroyed in places.
ATTRACTIONS
Jollybuoy
Of all these islands
Jollybuoy, which, lies towards the middle of the park, is most famous.
The biggest attraction of this island is a sandy beach on its northern
end. This beach is encircled by a reef, which is exposed during low
tide. Walking carefully over the area one can see the tide pools and in
them the sea cucumbers (Holothuroidea. sp), anemones (Heteractis crispa),
starfish (Ophioderma), cowries (Cypraeidae), turbots and spider conch (Lambis).
Redskin Island
Redskin Island is
another important island, which is inhabited by the deer, which were
brought here by the British. Approachable by boats that land in sandy
coves on either side of the island, Redskin has a large area with
numerous caves along the northern cliffs. The interior is still quite
densely wooded with mangrove stands along the eastern and southern
creeks. Across the channel is Tarmugli, which has an extensive coral
reef on the southwestern side and an idyllic diving cove at the extreme
end of the reef. Nearby is Grub Island, a picturesque sand fringed
island that is so small, one can walk around it.
At the southern end of the park lie the Twins. Aptly named, the two
peaks rise from the deep blue sea, separated by a thin strip clean and
clear water.
Marine Life
Having explored the
land, it is time to discover the marine life. It begins right at the
shore. Take a plunge into the deep and a whole new world unfolds through
the diving mask. At first sight everything appears to be a blue haze.
Slowly it begins to unravel . the sand below, the coral heads and the
amazing variety of fish: brightly colored green parrot fish (Cheilinus
digrammus), blue damsels (Chrysiptera cyanea), yellow butterfly
fish (Chaetodon sp), black surgeons (Acanthurus sp),
silver jacks (Carangidae sp) . a never-ending parade of sea life.
The richness and diversity of the life on the coral reef is amazing.
Take the coral for example . a simple skeleton made up layer by layer by
the minute coral polyp. It comes in all shapes, sizes and colors. Of the
over 1000 existing species in the world, 135 are found in the Andaman.
s, alone.
The coral reef itself is made up of solid limestone built over ages
through a process of sedimentation. Boulders, walls, peaks, valleys,
nooks and corners form the general topography. Brain coral, finger
coral, antler coral are some of the common varieties encountered. Plate
coral, vase coral and leather coral are scattered all over the reef in
patches.
If examined closely it is possible to distinguish the individual coral
polyps. Some are as small as a few millimeters where as others can be
about a centimeter long. Tentacles, which serve the purpose of
collecting food, surround their centrally placed mouth. Though they
might look insignificant, all corals, whether branching or spreading are
the creation of these countless individuals working in harmony.
Corals derive their color from algae called xooanthellae living inside
their flesh. This symbiotic relationship is characteristic of many other
species of the reef. The algae help in the formation of the hard
limestone coral skeleton and in return it utilizes the coral. s
metabolic wastes as nutrients.
As the reef is built up over the years it serves as a shelter and haven
to other marine life. Fish, crab, lobsters, sea urchins, and shrimps .
all start forming the intricate food web, which binds all these
creatures to each other. Eat or be eaten is the universal law here. This
food web often ends with the most voracious predators. On the reef these
are the grouper, the barracuda and the shark. They patrol the outer
edges of the reef in search of prey. One wonders who the sharks are prey
to.
One of the most interesting sights on the reef is the cleaner wrasse.
This particular fish has evolved an innovative and specialized feeding
behavior. Its principal food consists of small parasites and to obtain
them, it offers a . cleaning service. to other fish as most fish have
these pests clinging to them.
Proceeding further along one is likely to come across the giant clam. It
is a spectacular sight with its luminescent mantle. Small ones are
easily spotted but the real three feet giant clams are said to exist
only along the remote fringes of the park.
Another curious sight is the big anemone and its clownfish that live in
association, forming one of the well-known cases of symbiosis. The
mobile clownfish cleans and feeds the fixed anemones while the anemone
offers shelter to the fish. The anemones can sting mildly and it is
best, not to touch them. Then there are five species of clownfish, which
occur in the park. Some can be found in three feet of water and easily
observed by the snorkeler.
Mangrove
Another marvel of these
islands is the mangrove. This hardy tree has its roots in seawater. The
leaves and other debris of the mangrove form a very important source of
food to the marine life. Like the reef this tree provides a natural
buffer against storm waves.
REACHING THERE
Regular flights from
Port Blair to Calcutta and Chennai are operated by Indian Airlines. One
can travel to Wandur, from Port Blair, by road.
For moving inside the park, the forest department runs a launch service,
which visits two or three islands daily. More enterprising parties hire
motorized canoes from local fishermen and head for the less frequented
areas. It is essential to take along the fisherman as a guide for safe
trips.
STAYING THERE
Good accommodation
options are available at Port Blair, which is about 30 km from the park.
National Park also has some good accommodation options. |
