The “Island In The Sun” is the title song of the 1957 movie bearing the same name. It was written by Irving Burgie and sung by Harry Belafonte.
Oh island in the sun
Willed to me by my father’s hand
All my days I will sing in praise
Of your forest waters, your shining sand
As morning breaks, the Heaven on high
I lift my heavy load to the sky
Sun comes down with a burning glow
Mingles my sweat with the earth below
Oh island in the sun
Willed to me by my father’s hand
All my days I will sing in praise
Of your forest waters, your shining sand
I see woman on bended knee
Cutting cane for her family
I see man at the waterside
Casting nets at the surging tide
Though this song addresses the island of Jamaica, it is equally applicable to Sri Lanka the pearl of the Indian Ocean and nature’s treasure chest.
.
Sri Lanka, also known as India’s Teardrop and the Pearl of the Indian Ocean, is an extension of peninsular India that got separated from the mainland.
.
The island paradise, formerly known as Ceylon until 1972, is in the northern Indian Ocean off the southeast coast of the Indian subcontinent in South Asia. Sri Lanka has maritime borders with India to the northwest and the Maldives to the southwest. It is one of the most delightful destinations in the world to visit.
Sri Lanka is the home to one of the oldest civilizations in the world. Though the island’s documented history spans over 2,550 years, evidence shows that it had prehistoric human settlements dating back to at least 125,000 years. Its history boasts of planned cities, magnificent palaces, temples, and monasteries, expansive reservoirs, green forests and gardens, monuments and works of art.
Sri Lanka due to its geographic location and endowed with natural harbours has been the cynosure of strategic importance from the time of the ancient Silk Road through to World War II.
Today, Sri Lanka is a republic and a unitary state governed by a presidential system. The capital, Sri Jayawardenepura Kotte, is a suburb of Colombo, Sri Lanka’s largest city.
Sri Lanka is home to many races speaking diverse languages, and following different religious faiths. It is the land of the Sinhalese, Sri Lankan Tamils, Indian Tamils, Moors, Burghers, Malays, Kaffirs and the aboriginal Veddas.
The island has a rich Buddhist heritage spanning from the time of the Indian Emperor Ashoka Maurya (304–232 BC) of the Maurya Dynasty who ruled almost all the Indian subcontinent from circa 269 to 232 BCE. The first known Buddhist writings of Sri Lanka, the Pāli Canon dates back to the Fourth Buddhist Council in 29 BCE.

The island is one of the most beautiful and delightful destinations in the world for tourists to visit. Its historical planned cities, magnificent palaces, temples, dagobas, monasteries, monuments, sculptures and other works of art, expansive artificial reservoirs, green gardens, etc., illustrate the characteristic rich history of its ancient rulers.

Why am I interested in wetlands and writing about them?
Because I am concerned.
I am not an environmentalist per se. I am just a layman. I seek protection of our natural environment from changes made by harmful human activities. I yearn for improvement in the quality of our surroundings worldwide for the benefit of our present and future generations.
My home in Jalladianpet in Chennai, Tamilnadu, India is just 2.5 miles (4 km) from the Pallikaranai wetland. Now, this once pristine idyllic wetland and many other smaller wetlands, pasture lands and patches of dry forest in Chennai are being transformed into concrete jungles!
That is why I am concerned.
What is a wetland?
A wetland is technically defined as:
“An ecosystem that arises when inundation by water produces soils dominated by anaerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding.“
Wetlands consist of hydric soil, which supports aquatic plants. The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation that adapts to its unique soil conditions and the fauna that inhabit it
There are four main kinds of wetlands: marsh, swamp, bog and fen. Sub-types include mangrove, carr, pocosin, and varzea. Some experts also include wet meadows and aquatic ecosystems as additional wetland types. (Read my article: Save the Wetlands)
Wetlands of Tamilnadu, India
There are three wetlands in the state of Tamilnadu, in India: Point Calimere, Kazhuveli, and Pallikaranai.
In 1985-86, the National Wetland Conservation and Management Programme (NWCMP) of the Government of India listed Point Calimere, Kazhuveli Wetland, and the Pallikaranai Marsh among the 94 identified wetlands in India.
Point Calimere, Kazhuveli wetland, and the Pallikaranai wetland are three of the 94 identified wetlands under
The forests of Point Calimere
Point Calimere, also called Cape Calimere (Tamil: கோடியக்கரை Kodiakkarai), is a low headland on the Coromandel Coast, in the Nagapattinam district of the state of Tamil Nadu, India.
The forests of Point Calimere are also known as the Vedaranyam forests. They are the last remnants of the East Deccan dry evergreen forests.

On June 13, 1967, the Point Calimere Wildlife Sanctuary with an area of 24.17 square km was created. The sanctuary includes the cape with its three natural habitat types: dry evergreen forests, mangrove forests, and wetlands.
The Kazhuveli wetland
Kazhuveli the second largest brackish water lake in South India lies adjacent to the Bay of Bengal along the East Coast Road. It is located about 18 km north of Pondicherry in the Tindivanam Taluk of Villupuram district in Tamil Nadu.
Once a mangrove forest, Kazhuveli, has degraded over a period of time. It encompasses about 15 villages with a catchment area of 4,722 hectares. A total of 196 minor irrigation tanks and ponds drains into the Kazhuveli wetlands.
Now, the entire ecosystem of Kazhuveli wetland is completely destroyed and denuded by human inference, chiefly, due the growth of salt pans and aggressive fishing. It is one of the prioritized wetlands of Tamil Nadu.

The Pallikaranai wetland is among the few and last remaining natural wetlands of South India.
Historically, a large part of South Chennai was a flood plain composed of the large Pallikaranai wetland, smaller satellite wetlands, large tracts of pasture land and patches of dry forest.
The Pallikaranai wetland is a freshwater marshland spanning 31 square miles (80 square km). It is the natural primary aquifer recharge system for Chennai city.

The Pallikaranai wetland situated adjacent to the Bay of Bengal, is about 12.5 miles (20 Km) south of the city centre. Bounded by Velachery (north), Okkiyam Thuraipakkam (east), Medavakkam (south) and Kovilambakkam (west), the Pallikaranai wetland is the only surviving wetland ecosystem of the city.

The terrain consists of fresh/saline water bodies, reed beds, mud flats and floating vegetation.
The original expanse of the Pallikaranai wetland, estimated on the basis of the Survey of India toposheets (1972) and CORONA aerial photographs (1965) was about 5,500 hectares. This vast area has now been reduced to about 600 hectares.
Flora and Fauna
Vedanthangal bird sanctuary in the Kancheepuram District in Tamil Nadu, India, is 47 miles (75 km) from Chennai. It hosts more than 40,000 birds (including 26 rare species), from various parts of the world during the migratory season every year.
Now, Pallikaranai wetland is almost four times the size of the Vedanthangal bird sanctuary and is literally a treasury of bio-diversity.
The Pallikaranai wetland has several rare and endangered species of flora and fauna. The marsh acts as a forage and breeding ground for thousands of migratory birds from various places within and outside the country. Bird watchers opine that the number of bird species sighted in the Pallikaranai wetland is definitely more than what they get to see in the Vedanthangal bird sanctuary.
Figures of the number of fauna and flora found in the Pallikaranai wetland differ among scholars conducting research here.
Among the many quiet contributors to the mapping of India’s natural treasures is Dr. Jayashree Vencatesan, Smithsonian Fellow and researcher, and managing trustee of Care Earth Trust. She obtained a Ph.D. in Biodiversity and Biotechnology from the University of Madras. She is best-known for her research work on biodiversity and studies in wetland ecology.
Dr. Jayashree Vencatesan
In 2003, the Tamilnadu State Pollution Control Board assigned to Dr. Jayashree Vencatesan the task of conducting a detailed study of Chennai’s last remaining wetland – the Pallikaranai marsh, which is suffering from degradation caused by human impact. The study had two components – to document the biodiversity and to map the extent of the marsh to define or identify a viable unit of management.
In her work “Protecting wetlands” published on August 10, 2007, Current Science 93 (3): 288–290, she states that the heterogeneous ecosystem of the Pallikaranai marshland supports about 337 species of floras and faunas:
Birds, fishes and reptiles are the most prominent of the faunal groups.
Dr. K. Venkataraman
However, on August 9, 2013, P. Oppili reported in The Hindu that Dr. K. Venkataraman, Director of Zoological Survey of India (ZSI) while discussing the diversity of species in the marshland, as nine species of amphibians, 21 species of reptiles, 72 species of birds, five species of mammals, 38 species of fish, nine species of shells and 59 species of aquatic and terrestrial insects had been recorded, besides a good number of plankton.
The Pallikaranai wetland is the home to some of the most endangered birds such as the glossy ibis, gray-headed Lapwings and pheasant-tailed Jacana.

The Pallikaranai wetland is also home to some of the most endangered reptiles such as the Russell’s viper.
About 114 species of plants are found in the wetland, including 29 species of grass. These plant species include some exotic floating vegetation such as water hyacinth and water lettuce.
Since 2002, presence of new plants and reptiles have been recorded.

I proudly shared the above photograph of a house I came across on facebook.
The owner of the house, I presume, must be a lover of nature and a “Save the Trees” activist because he has built the house including the tree that was obstructing the frontage of his house.
Clever thinking, isn’t it?
Impressed by this builder’s feat, I chipped in and wrote: “Hats off to the owner of this house.”
However, my friend Joe Croos from Germantown, Maryland, USA, cut my ego down to size with his wise quip:
“If I were the local thief the owner would be my sweetheart.“
I realized my folly for not thinking about the security and safety of the people living in that house and so, I acknowledged Joe’s shrewdness:
“Joe, I did not think from your angle. You are indeed a genius … “
Studies show that an invertebrate successfully colonized Hawaii once in every 70,000 years, a plant once in every 100,000 years, and a bird once in every million years.

Officially and technically, Hawaii doesn’t have any snakes.
Why?
All Hawaiian Islands are volcanic in origin. Over the past 44 million years, the islands rose up from the ocean floor due to erupting volcanoes. Even today, the youngest island, Hawaii, is still growing from under.
.

Hawaii is the most isolated archipelago in the world. The nearest continent, North America, is over 2500 miles (4000 km) away.
The extreme isolation of the Hawaiian archipelago makes it difficult for plants and animals to colonize its islands. The only way for wildlife species to reach the Hawaiian Islands from the rest of the world is to fly or swim across the Pacific Ocean. Chances of surviving the long journey over Pacific by air or sea is virtually small. It would indeed be a miracle to establish a reproducing population on these islands. Since there are no natural predators and diseases in Hawaii, many native plants and animals needed only a few natural defenses to evolve. Studies show that an invertebrate successfully colonized Hawaii once in every 70,000 years, a plant once in every 100,000 years, and a bird once in every million years. This is why it took over millions of years for a very distinct flora and fauna to evolve in Hawaii.

Before humans set foot in the Hawaiian paradise, there were no large animals to eat plants. Harm to the flora and fauna on the islands began about 1500 years ago when settlers started arriving from Polynesia. Mammals such as pigs, dogs, goats and plants brought by them literally devastated many native ecosystems.
It is illegal to own snakes or transport snakes of any kind to the Hawaiian islands. Anyone possessing a pet snake has to face jail up to 3 years and $200,000 in fines. In Hawaii there no natural predators for snakes and large lizards, therefore, if allowed, could pose a threat to Hawaii’s ecosystem by competing with native animals for food and habitat. Some snake species prey on birds and their eggs, and hence could pose a threat to endangered native birds.
Blind Snakes
Hawaii doesn’t officially have snakes. However, there is one snake that does live in Hawaii, the Blind Snake (Ramphotyphlops hatmaliyeb) likely an import from the Caroline Islands in Micronesia, an area north of the equator and far west of Hawaii.
.
.
Addison Wynn, a herpetologist at the Smithsonian’s National Museum of Natural History who studies the blind snakes on the Caroline Islands says:
“They eat termites and small ants, and there are about 240 or so known species in the world. They spend their lives burrowing so their head is blunt and pointed to push their way through the soil. Their rudimentary eyes can only differentiate between light and dark and exist as pigment spots underneath scales on their head.
These new species extend the known range of blind snakes some 2,000 kilometers out into the Pacific Ocean, into areas where we didn’t know they occurred or could ever occur. We just didn’t expect to find blind snakes out there (Caroline Islands) in the middle of the ocean.”
Some other studies that the blind snakes found in Hawaii could have come there from far off the Philippines, about 5300 miles (8530 km) away.
So, other than the blind snakes, it is widely assumed that there are no snakes in Hawaii. Sadly, this is not true. According to a few reports, people have seen some snakes in Hawaii.

On May 23, 2013, military personnel at the Hickam Air Force Base captured a foot-long mildly venomous Ornate Tree Snake (Chrysopelea ornate) in a maintenance bay near the airfield.
Since the Ornate Tree Snakes are able to spring from tree to tree, they are also known as ornate flying tree snakes. These snakes are native to South East Asia and related to the brown tree snakes which have devastated the ecosystem in Guam by virtually wiping out the native forest birds. Their diet consists of lizards, mice, bats and birds.

On September 22, 2013, a motorist ran over a five-foot long Boa Constrictor on the Pali Highway. Several inspectors of Hawaii Department of Agriculture (HDOA) went directly to the area where the snake was found. However, they did not find evidence of any other snakes. Russell S. Kokubun, chairperson of the Hawaii Board of Agriculture said:
“Any snake found in the wild in Hawaii is of serious concern. Boa constrictors may grow up to 12 feet, which is particularly troubling for nearby residents and for the environment.”
.
Rainbow Boa Constrictor

.
At about 7 am on November 5, 2013, Victor Palmeri, found a live two-and-a-half foot long non-venomous Rainbow Boa Constrictor on the Nuuanu Avenue sidewalk fronting the Kukui Plaza condominium. Native to Central and South America, rainbow boas can grow up to six feet long. Rainbow boas are known for their attractive iridescent sheen on their scales in the sunlight. Their diet consists of rodents, lizards, aquatic animals, and birds.
It is not known at this time how these snakes found their way to Hawaii.
