#ATOZCHALLENGE DAY 21: V for VOLCANOES of the Islands

Every time you think there couldn’t be anything more to the Andaman and Nicobar islands and i drop a bomb!! 😉 Yes!! The more you ask the more you have to explore various wonders of nature in these islands.

The Andaman and Nicobar islands are home to not just one but TWO VOLCANOES – BARREN Island and NARCONDAM Island also only ones in India which makes it important considering there are only about 500 volcanoes on earth.

Barren Island houses the only active volcano in India. The volcanic islands like only about 195 km east of the capital city Port Blair. About 135 km north east of Barren Island lies the other volcano Narcondam Island with no such activity in history. After lying dormant for 150 years, Barren Island volcano erupted in 1991 and has been showing sporadic activity since then, scientists of Goa based National Institute of Oceanography (NIO) said.

Barren Island is roughly circular with a diameter of ~3 km and represents the topmost part of a submarine volcano rising more than 2 km above the sea floor. The highest point of the Barren Island volcano is ~200 meters from sea level. Barren Island is well known for its unique fauna and flora, including feral goats, as well as bats, parrots and large number of rats. 
There were past reports about the Barren Island that there are no fresh water source in Barren Island and the animals in the Island have adapted themselves to drink sea water is incorrect. At least 2 fresh water streams have been discovered in the Island and there is probability of more.

Eruption of 1991; PC – Andaman Gov

Volcano Eruptions : 1787–1832, 1991, 1994–95 and 2005–06. 2008-2009. During January and February 1995, a thick column consisting of pale brownish gas, dark ash particles, and white steam was rising ~200 m
from the crater area at intervals of 30 seconds, accompanied by continuous rumbling and intermittent “cracking” sounds.

The most recent activity of the volcano was this year March . The Coast Guard has presented footage of steam, smoke and some red lava that spewed from the volcano at Barren Island, some 140 kilometers north east of Port Blair. You can click the link below to watch the video. Night view of the Volcanic activity

How to go there:
It is a uninhabited Island and no one is allowed to land on Barren Island unless special permission(s) are granted by Indian Navy and Govt. of India. Though it is possible to observe the Island from on-board boats/ships for which no permission is required. Some travel agents organised fishing trips to Barren Island from Havelock. The nearest inhabited island is Havelock and Neil Island and the distance from there to barren is about 83 kilometers.
The Andaman Administration started ship trips to Barren Island for tourists (They were not allowed to set foot on Barren Island though) but discontinued the arrangement within few months probably because of operational costs.

NARCONDAM ISLAND:
Narcondam Island is a 6.8 km² oceanic island of volcanic origin located about 240 km northeast of Port Blair. The Island has been declared as one of UNESCO’s World Heritage Center.
Narcondam is unique for the occurrence of the endemic Narcondam Hornbill (Aceros narcondami), which is found only in Narcondam. This Narcondam hornbill has the smallest range among the 31 species of Asian hornbills (Kinnaird and O’Brien 2007). The species is recognized as endangered in the IUCN Red List and is protected under Schedule I of the Wild Life Protection Act of India granting it the highest level of protection in Indian Laws.It has a strong evolutionary significance and has even been compared with the Galapagos Islands.

The Hornbill birds are found only in the Narcondam island

The waters surrounding Narcondam Island are legendary for being a “diver’s paradise” considering the North Bay islands are close to this island which is famous for water sports activities. An extinct volcano, Narcondam was put on the diving map by diving pioneer Jacque Cousteau who was the first to dive in these waters, describing “a wondrous realm of stunning marine life and coral reefs”. The diving here features magnificent coral formations, spectacular rocky drop offs and presence of pelagic and majestic creatures such as Manta Rays; plus gas bubbles rising from fissures in the ocean floor.
Narcondam has a check post of the Andaman and Nicobar Islands Police which is supported in precisely this fashion, with some 20-odd members posted on duty for a few months by rotation. Of course, though Narcondam is a taller, larger island, mostly forest-covered and with very difficult terrain, the police check post there benefits from a never-drying cold freshwater spring.

Mud Volcano : As mentioned in my previous posts, the Baratang Island has the mud volcano which is the only one in Asia. You can see mud instead of lava being erupted of the volcano hole.If beaches were the only reasons for you to plan your trip to Andaman now you can add Volcanoes too 🙂 Do you have a Volcano in your place or country? Let me know!!

#ATOZCHALLENGE DAY 06: F for Flora and Fauna

Flora of the Islands
These Islands are blessed with a unique’ luxuriant evergreen tropical rain forest canopy, sheltering a mixed germ palms bank, comprising of Indian, Myanmarese, Malaysian and endemic floral strain. So far, about 2200,varieties of plants have been recorded out of which 200 are endemic and 1300 do not occur in mainland India. 

The Mangroves of Andaman and Nicobar Islands PC – Saketh

“The South Andaman forests have a profuse growth of epiphytic vegetation, mostly ferns and orchids. The Middle Andamans harbours mostly moist deciduous forests. North Andamans is characterized by the wet evergreen type, with plenty of woody climbers. The north Nicobar Islands (including Car Nicobar and Battimalv) are marked by the complete absence of evergreen forests, while such forests form the dominant vegetation in the central and southern islands of the Nicobar group. Grasslands occur only in the Nicobars, and while deciduous forests are common in the Andamans, they are almost absent in the Nicobars”. 

This atypical forest coverage is made-up of twelve types namely.

(1) Giant evergreen forest
(2) Andamans tropical evergreen forest
(3) Southern hilltop tropical evergreen forest
(4) Cane brakes
(5) Wet bamboo brakes
(6) Andamans semi-evergreen forest
(7) Andamans moist deciduous forest
(8) Andamans secondary moist deciduous forest
(9) Littoral forest
(10) Mangrove forest
(11) Brackish water mixed forest
(12) Submontane hill valley swamp forest.
The present forest coverage is claimed to be 86.2% of the total land area.

Andaman Forest is abound in plethora of timber species numbering 200 or more, out of which about 30 varieties are considered to be commercial. Major commercial timber species are Gurjan (Dipterocarpus spp.) and Padauk (Pterocarpus dalbergioides). Ornamental wood such as (1) Marble Wood (Diospyros marmorata) (2) Padauk (Pterocarpus dalbergioides), (3) Silver Grey (a special formation of wood in white chuglam) (4) Chooi (Sageraea elliptical and (5) Kokko (Albizzia lebbeck) are noted for their pronounced grain formation.  Padauk being steadier than teak is widely used for furniture making. With its abundance in the islands, its called the State Tree of the islands. Burr and the Buttress formation in Andaman Padauk are World famous for their exceptionally unique charm and figuring. Largest piece of Buttress known from Andaman was a dining table of 13’x 7′. The largest piece of Burr was again a dining table to seat eight persons at a time. The holy Rudraksha (Elaeocarps sphaericus) and aromatic Dhoop/Resin trees also occur here. There is one Rudraksha tree near my uncle’s home 🙂 

You can find almost all the tropical fruits in these islands like any other tropical region but there is one rare fruit which is found and eaten in the Nicobar islands the Pandunus or Nicobar Breadfruit 

Pandanus is a densely arranged, wedge-shaped fruit that has an immensely hard, woody and fibrous body in which several narrow, edible seeds are embedded. Each section has a fleshy base that contains an aromatic pulp that, after cooking, is a staple food in Nicobar. An economically important plant in the islands, the stem branches of Pandanus are used in construction, the leaves used for weaving mats and the hard exterior of the fruit is used as a bathing brush.

Fauna of the Islands
This tropical rain forest despite its isolation from adjacent land masses is surprisingly enriched with many animals. I have already introduced you to the State Animal in my previous post – the Dugong Similarly we have the State Bird of the islands which is the Wood Pigeon,
the pigeon being endemic to these islands lives in the dense evergreen forests.

About 50 varieties of forest mammals are found to occur in A&N Islands, most of them are understood to be brought in from outside and are now considered endemic due to their prolonged insular adaptation. Apart from these there are some famous birds and species endemic to the islands alone like the below 

The Hornbill birds are found only in the Narcondam island, which is also famous for having the inactive volcano.

from online birds database

The Megapode bird or the mound bird is known for laying eggs in holes in the ground or in mounds of rotting vegetable matter and leaving them to be incubated by heat from the Sun or volcanic action. Mound birds are also called mound builders, incubator birds, or megapodes. 

The Robber Crab (Birgus Latro), also called the Coconut Crab, is the largest land-living arthropod in the world. They generally live on land, but at nights climb up the coconut trees and carve a hole into the tender coconuts to eat the soft kernel. In South Asia, the highest numbers of these huge crabs are found in the Andaman and Nicobar archipelago. They can be spotted on the South Sentinel Island as well as on some islands in Nicobar. Apart from these there are wide variety of other crabs which are found in these islands. They are also one of the favorite delicacies the locals love. (i love eating crabs too <3, not this one for sure).

Also found in abundance specially in the Ross Islands are the Deer and Peacock 

 

The happy land of butterflies 
With about 225 species, the A&N Islands house some of the larger and most spectacular butterflies of the world. Ten species are endemic to these Islands. Mount Harriet National Park is one of the richest areas of butterfly and moth diversity on these Islands. Thousands of butterflies flock to the Andaman Island every year. I.e Andaman is a proud host to butterflies that migrate to the islands. Even postal stamps have been issued in honor of this phenomenon 

The Amazing Marine Life of Andamans
If Dugong was the only herbivore mammal under water that is found in the Andaman islands, there are many more amazing marine life that is still majorly unexplored.
Dermocheleys Coriacea, the largest sea turtles in the world nest in the Andaman islands. They are huge in size and thousands of them flock to the Andamans every year. Additionally, even the Olive Ridely turtles come to the Andamans and use it as their nesting ground.
In fact the Kalipur beach in Diglipur is the only place in the world that boasts of nesting by four types of sea turtles viz., Leatherback turtle, Olive Ridley, Green Turtles and HawksBill.

Quick info – if you ever take a ship to the Andaman and Nicobar Islands (yes we do have ships that take 3 days from Chennai, Visakhapatnam and Kolkata to reach the islands), about an hour before you reach the harbour you would be lucky to find group of dolphins giving you company till the ship reaches the port. Below is one such capture by a APS director Rathnam. I can personally vouch cause i have seen them when my family used to travel by ships during summer vacations. 

With an abundance of sea creatures, the islands staple source of food is also the sea. From crabs, to shrimps and lobsters , there are over a hundred variety of fishes that are eaten by the locals. Some people are also known to have sea urchins and sea cucumbers which are now available only in the interior islands.

Some of the well known aquatic animals of Andamans are the Humphead Parrotfish, Whitebanded Shrimp, Peacock Mantis, Giant Moray , Manta Ray. 

Since the islands are surrounded by water from all around its obvious to have an amazing variety of shells and corals. Snorkeling and Scuba diving water activities are a great means to explore the corals.  
As always ending the post with some additional info. Check out the below video(highly insist) which was captured by my friend  Saketh and Sanjay  from our recent trip to Andamans .
