The Violet Cuckoo Tree

Our house in Salt Lake enjoys the privilege of being located next to a vacant plot. Attempts have been made several times in the past to tame that small patch by cutting down the weeds and shrubs, burning them, and even plundering trees with JCB. Nature being a stubborn donkey still finds its way. A Jungle Jilipi/Babla (Pithecellobium dulce) tree stands on that patch. It has been standing for a long time. It has weathered many storms, broken down, and recovered with equal gusto.

I have seen so many bird species over the years on this particular tree that I have grown extremely fond of it. I have mentioned several times in the past that this particular tree, the Jungle Jilipi is a bird magnet. Over the years, I have initiated my son into bird-watching just by pointing him at the birds that visit the tree. Life might have been different without this tree. The spiral Jilipi like fruit resembles tamarind with reddish skin. Once the outer case is stripped off, white edible flesh is visible. Children in the villages do eat the white flesh. Even a decade back, lesser privileged children could be seen pelting stones in an attempt to get hold of the fruits. Inside the white flesh lies slightly triangular flat-shaped black seeds. Natural germination in this soil and climate is excellent.

The fruits start appearing at the end of March and continues for the next three to four months. Fruits are produced in abundance. This is the time one can see the maximum number of birds. The Rose-Ringed Parakeets are regulars. Even late in the evening, we see them from the rooftop almost at eye level or slightly higher, enjoying the fruits. Like humans, the birds also strip away the outer casing and consume only the white flesh surrounding the seed. We have also recorded Alexandrine Parakeets feeding on the fruits. The Coppersmith Barbet, Blue-throated Barbet, Asian Koels, and Red-vented Bulbuls can be found in plenty during the fruiting season. The Asian Koels remain inside the tree for the entire duration of the day and night during springtime. Their calls are unmistakable. I do not understand the bulbuls because I find them on the tree in large numbers even outside the fruiting season. In spring, the Oriental Magpie Robin perches on the topmost branch and continues with his song. Oriental Magpie Robins keep flitting around the tree but I have never seen them eating the fruits. They stick to insects, I guess.

The scene around this tree is no less spectacular when it is flowering from around December to March. Flowering is profuse. In this period, our regular visitors are the Purple Sunbird, Purple-rumped Sunbird, and Common Tailorbird. Even House Sparrows can be seen, but probably they are after the insects. The flowers attract a lot of insects which in turn bring winter visitors like the Taiga Flycatchers, Blyth’s Reed Warblers, and Thick-billed Warblers. Taiga Flycatcher and Blyth’s Reed Warbler are quite common in this period. An occasional Brown Shike can also be spotted sitting motionless on the lower branches but they are rare nowadays. During winter, a group of four to five Green Bee-eaters come regularly in the morning to sit on the tree canopy and hawk insects in flight. They are nowhere to be seen for the rest of the year. Black-hooded Orioles are quite common. Also, an adult and a juvenile Golden Oriole have been visiting regularly during this winter. They spend several hours in the tree. I hardly try to spot them but I can sense their presence from their screech-like calls.

The only raptor I find in this tree is an occasional Shikra. The Shikras are common in our neighborhood but very rarely do Shikras perch on this tree. Probably, they do not like the thorns which cover the young branches or they love trees with bigger leaves and denser canopy. Just my guess. The Shikras mostly perch on the large Jamun tree (Syzygium cumini) nearby.

Would you be surprised if I tell you that we have even seen and photographed two kingfishers on this tree? The White-throated Kingfisher and the Stork-billed Kingfisher. The White-throated Kingfisher uses the lower branches as a perch to swoop down on the lizards. The Stork-billed Kingfisher comes rarely but it does come. My neighbor even has a beautiful photo of it perched on this tree.

The monsoons bring in more insects and insect larvae. Pithecellobium dulce appears prominently as a larval host plant for four to five species of butterflies. The butterfly which I find regularly in monsoon is the Common Grass Yellow and I am sure they lay the eggs on the Jungle Jilipi. I have also observed Indian Jezebel and Tailed Jay during the flowering season. The monsoon also brings in dense undergrowth. A pair of Greater Coucals and the chatty Jungle Babblers keep us engaged throughout the day. The wet floor provides them with juicy insects. The Black-rumped Flameback also visits during this period.

Some star visitors have also visited this tree, but only once. In the recent past, I remember photographing a Black-winged Cuckooshrike (7th April 2021) and a Plaintive Cuckoo (22nd Nov 2021) from our window. Needless to say, I was elated on both occasions.

When the first news and images of the Violet Cuckoo being spotted in Salt Lake spread, I was excited. What immediately struck me was the tree. It was a Pithecellobium dulce. Since the first sighting, the bird has remained faithful to the Jungle Jilipi. There is one large Jungle Jilipi and two smaller Jungle Jilipi trees in the vicinity which feed the bird well with insects, mostly caterpillars. My favorite tree is now playing host to the most sought-after and photographed bird in town!!

The tree in our backyard has overgrown and invaded our rooftop. The climber from our garden mingles freely over the Jungle Jilipi tree. I do not mind. Nor do the birds seem to mind.

The Blessed Child of the Bhagirathi

Text and Images By Soumya Kundu

Genesis

In the district of Murshidabad (state: West Bengal), the main channel of the Ganges river, or Ganga as we call her crosses over to Bangladesh. A distributary of the Ganges called Bhagirathi starts near Giria (northeast of Jangipur in Murshidabad) flows south through West Bengal for 190 km to join the Jalangi river at Nabadwip in the district of Nadia. Thereafter, the river is called Hooghly. Bhagirathi, once the main channel of the Ganges, lost her glory when the Ganges shifted her main course westwards towards Bangladesh. Today, Bhagirathi in addition to the water she receives through the natural river channel is boosted by the water diverted from Farakka Dam through the 38.3 km long Farakka Feeder Channel.

Bhagirathi is a river full of character. She runs a meandering course through Bengal. Her capricious nature has created ox-bow lakes, mid-channel bars, interesting meander geometries, and lateral migration along her course. Around 1989-1991, the youthful river shifted eastward while giving birth to an oxbow lake on the western bank between Sajiara (district Purba Burdwan) and Mayapur (district Nadia). Thus, at the border of the districts, Nadia and Purba Burdwan was born a 9 km long freshwater oxbow lake with a water area of around 3.5 sq km (shrunk to 2.19 sq km in 2017). The local people named her “Chhariganga”. The villages on the northern part of the lake are known locally by the names Chupi and Kasthashali. The entire area including the lake (except for a few villages like Idrakpur) lies in the Purbasthali-II block within the Kalna subdivision of Purba Burdwan. Hence the lake is also known as Chupi Beel or Purbasthali Oxbow Lake. 

However, Bhagirathi did not abandon her child altogether. She continued to provide nourishment to her newborn through an umbilical cord-like channel that still connects the lake to her mother at the southern portion. To this day, Purbasthali Oxbow Lake continues to receive fresh water, silt, and nutrition through this channel all year round and in large quantities during the monsoon.

Nature blessed this child of Bhagirathi and soon the aquatic ecosystem of this oxbow lake of Chhariganga became rich in biodiversity. Aquatic plants of all types viz. floating, emerging and submerged started to grow naturally. Fishes abounded, as were other insects and crustaceans. As it happens across the globe, an abundance of one lifeform helps to sustain other lifeforms in that ecosystem. The same happened at Purbasthali Oxbow Lake. The migratory birds were quick to find this flourishing ecosystem and they started descending on the lake in large numbers for food and rest. The local resident birds also moved in and made the lake their feeding, hunting, and breeding grounds. It is believed that as many as fourteen thousand waterbirds used to congregate in the lake around the year 1992. In 2013, a census of twenty common waterbirds (resident, migratory and local migratory) in the lake put the count at close to ten thousand individuals.

Shoot Them, Eat Them

Purbasthali Oxbow Lake is surrounded by villages and is close to the major town of Nabadwip and the temple town of Mayapur. As early as 1988, when the lake was in the formative stage and not fully cut-off from Bhagirathi, the people around had started to notice the huge congregation of waterbirds in winters. Poaching of migratory birds became rampant. Awareness about conservation was minimal and the police were more occupied with the deteriorating law and order situation of that region. Enforcement of the Wildlife Protection Act took a backseat. The poached birds were often consumed by the locals for the delicious meat (as described by a local boatman) and also sold to wayside eateries to be cooked for prospective clients. In the year 1992, a local NGO named Junglees spearheaded by Raja Chatterjee started a mass awareness campaign with some help from the government. Pamphlets urging the villagers not to kill birds and to treat them as friends were distributed. Workshops were held with various stakeholders. The major stakeholders were the boatmen who earned a living catching fish in Purbasthali Lake. Purbasthali Lake hit the headlines of several regional and national level newspapers (see The Hindu, 6th March 1995 report by Parth Sanyal titled “Will these birds return?”). Sustained campaigning, liaison with the law enforcement departments, and the success of ecotourism helped to eventually stop poaching activities. Today, poaching is no longer a major threat to the migratory birds arriving at the lake.

A Bird Photographer’s Paradise

On a cold foggy morning in January, I was greeted at the Chupir Char by the familiar smile of my favorite boatman. I settled down in his small country boat with my mobile, binoculars, bird-book, camera, a heavy telephoto lens, water, and some food. Birdwatching from the boat in Purbasthali is a marathon eight-hour-long session. Small quantities of food and water are a must. As the majhi rowed the boat and steered it away from the banks, I marveled at the crystal clear waters of the lake. The fog had just started to lift and there was a promise of a clear blue sky. Sailing on the lake is itself a blissful affair. The fact that there are no motorized boats on the lake coupled with the fact that the birds do not treat the country boats as a threat, allows photographers to approach very close to the birds. The low height of the country boat lets you shoot most of the open water birds, wader-birds, and kingfishers at eye level.

We spotted a Common Kingfisher Alcedo atthis perched on a short bamboo pole jutting out of the lake. He had just caught his morning fish and we witnessed the tossing, turning, and flipping before the meal was gulped down. To be within a distance of six feet of a Common Kingfisher and to witness and capture such moments brings great joy. The serenity was only to be broken by the whistling calls of an approaching flock of birds. The large flock of Lesser Whistling-Ducks Dendrocygna javanica flew right over our heads. We saw several large flocks of Lesser Whistling-Ducks throughout the day. Lesser Whistling-Ducks are local migrants. They congregate in large numbers in winters at the lake. Once the winter is over, they disperse in smaller groups to other smaller water bodies nearby, where they breed. I scanned the birds sitting inside the Water Hyacinths Eichhornia sp. carefully with my binoculars hoping to find a Fulvous Whistling-Duck Dendrocygna bicolor but luck was not in my favor that day. Instead, I found a Baillon’s Crake Zapornia pusilla, a beautiful small migratory crake scampering over the floating plants. 

Then came the ubiquitous Little Grebes Tachybaptus ruficollis. You spot them and the moment you point the lens, they vanish inside the water, only to resurface several feet away. A small group of seven Cotton Pygmy-Goose Nettapus coromandelianus was spotted by my majhi. It requires mention that there are a few experienced majhis at Purbasthali who are not only exceptional spotters, but they have picked up the English names of most of the birds from the birders who come to the lake.

The Bronze-winged Jacanas Metopidius indicus, Pheasant-tailed Jacanas Hydrophasianus chirurgus, Grey-headed Swamphens Porphyrio poliocephalus were found in plenty flitting in and out of the Water Hyacinths thickets. The Great Egrets Ardea alba, Purple Herons Ardea purpurea, Grey Herons Ardea cinerea were also observed waiting patiently for their catch. These species are the permanent residents of the lake and they breed in and around the lake. The Black-winged Kite Elanus caeruleus appeared briefly, hovering over the lake. It had no business at the lake. Its interest lay in the agricultural fields on the banks.

Along the banks, there were large tracts of soft mud where the water was only an inch or two deep. Here at the edges, I photographed a beautifully camouflaged Common Snipe Gallinago gallinago and saw several other migratory waders like the Common Greenshank Tringa nebularia, Spotted Redshank Tringa erythropus, Common Sandpiper Actitis hypoleucos, Wood Sandpiper Tringa glareola, Green Sandpiper Tringa ochropus, Kentish Plover Charadrius alexandrinus, White Wagtail Motacilla alba, Western Yellow Wagtail Motacilla flava, Citrine Wagtail Motacilla citreola and one single individual of Little Ringed Plover Charadrius dubius. It was evident that there was plenty of food for them in the mud to survive. In the distance, a flock of Cattle Egrets Bubulcus ibis followed two bullocks as they dug the farmland. At the shallow edge, the Asian Openbills Anastomus oscitans were probing for snails. A pair of Grey-headed Lapwings Vanellus cinereus stood motionless on the slightly raised mud embankments.

However, for the bird photographers, the prize-catch is the beautiful Red-crested Pochard Netta rufina and the powerful fish-loving Osprey Pandion haliaetus. Eurasian Marsh-Harrier Circus aeruginosus also brings a smile to their faces. All these three species are winter migrants to the lake. I myself had no specific targets for the day but when I saw my majhi struggling hard to create a path through the waterway clogged by massive growths of Water Hyacinths, I sensed that he was up to something. After half an hour of struggle through the Hyacinth thickets, the boat reached clear waters. Lo and behold. In front of us were around twenty-five Red-crested Pochards. The light being favorable, I took some beautiful shots. Needless to say, I was partial to the males. By taking advantage of the low seating position and by positioning the boat for favorable light, photographers often make beautiful takeoff shots of the pochards and other ducks from this lake. The reason why Red-crested Pochards stick to certain parts of the lake would be revealed later.

The Red-crested Pochards brought good luck. We soon spotted four to five individuals of Ferruginous Ducks Aythya nyroca nearby. As for Tufted Ducks Aythya fuligula, we found only two of them. Through the binoculars, quite far in the distance on a patch where boats could not reach due to shallow waters, we spotted hundreds of Gadwalls Mareca strepera, a few Northern Pintails Anas acuta, several Glossy Ibis Plegadis falcinellus, and a few Black-headed Ibis Threskiornis melanocephalus

Emergent vegetation like the Cat-tail/Hogla Typa sp. and other tall grasses had claimed certain parts of the lake. In these patches, we found the Clamorous Reed Warbler Acrocephalus stentoreus and the Brown Shrikes Lanius cristatus. Both the species are long-distance migrants who spend the winter at the lake. A resident Greater Coucal Centropus sinensis and a couple of Long-tailed Shrikes Lanius schach were also spotted. It would be unfair if I make no mention of the cormorants which were spotted in abundance. The lake is a perfect place to study the shape of the beak and the color of the eye of the migratory Great Cormorant Phalacrocorax carbo and Indian Cormorant Phalacrocorax fuscicollis. Since all the three cormorants can be found in one place, their sizes can also be compared.

Around mid-day, we observed the hovering of a Eurasian Kestrel Falco tinnunculus. The lull of the afternoon which had set in was suddenly broken by a cacophony of bird calls as a large flock of resting water birds took to their wings in a hurried manner. Investigating the cause, we found a Eurasian Marsh-Harrier descending from the sky. 

The abundance of kingfishers at the lake was proof that there were plentiful fishes. At the end of the day, four species of kingfishers were photographed, viz. Common Kingfisher, Pied Kingfisher Ceryle rudis, Stork-billed Kingfisher Pelargopsis capensis, and White-throated Kingfisher Halcyon smyrnensis. The White-throated Kingfisher which is the black sheep of the kingfisher family was spotted with a massive catch of a frog.

I forgot to mention our constant companion, the Barn Swallows Hirundo rustica. With relentless energy and in large numbers they kept flying around the boat, swooping down close to the water to hawk insects in flight. At times, they would rest at the tip of the jutting bamboo poles. In spite of their diminutive size, the blue metallic sheen of their feathers and the row of white spots on the tail (visible only in flight) made them look very attractive.

The sun was about to set and I was about to wrap up for the day. But the show was not over. The sky was filled with innumerous small birds which flew haphazardly all across. These were the Small Pratincoles Glareola lactea. They were the evening visitors to the lake who came for the flying insects.

With tons of images on the cards and with the ebird checklist showing more than fifty species recorded, I was a happy man ready to head back to my home in Kolkata. Kolkata is four hours drive away. By train, the nearest station is Purbasthali from where electric rickshaws are available for a drop to the Kasthashali Chupir Char picnic spot. The boating starts from this spot. Trains for Purbasthali leave at regular intervals from Sealdah and Howrah stations in Kolkata.

Red-crested Pochards

The Red-crested Pochards of Purbasthali

After a long migration from their breeding grounds in Central Asia, the Red-crested Pochards arrive at Purbasthali Lake around October and November. The long migration takes a toll on their fat reserves and leaves them totally exhausted. They look haggard, dull, and almost ugly. They feed voraciously at the lake and regain their beauty within a month of their arrival. It had intrigued me for a long time why Red-crested Pochards were more choosy than other migratory birds and stuck to only a few wetlands in Bengal.

I found the answer on one outing to Purbasthali. Luckily that day, I had with me a bright young lady who was a Zoology student. Taking photographs was not the main priority for that day. We spent more time observing birds, having fun, and even pulling out different aquatic plants with the help of oars. Whoever has been to the lake, cannot help but marvel at the beauty of the submerged plants beneath the lucid waters. After pulling out one such aquatic plant, I was photographing it with my mobile, when she casually remarked, “Sir, this is Chara. Don’t mistake it for an aquatic plant though it looks like one. These are algae.” There was no hesitation on her part. She was sure of the identification. I made a note and returned home.

As I was reading up on the Chara genus I learned that Chara sp. constitutes a significant part of the diet for the Red-Crested Pochard. Flashes of conversation with the majhi came back to my mind. The majhi had told me that these pochards would stick to only those parts of the lake where a certain underwater aquatic plant grew in abundance. It all made sense. This macrophyte, this algae of genus Chara was probably the reason why the Red-crested Pochards make Purbasthali Lake their wintering grounds.

The Macrophytes of Purbasthali Lake

The biota of the lake comprises several species of macrophytes or aquatic plants. The health of these macrophytes and their diversity are indicators of the health of the ecosystem and play a vital role in sustaining several lifeforms including birds. Some macrophytes recorded from the lake are broadly categorized and outlined below:

Emergent

  • Macrophytes are rooted in the lake bed but a major part of the plant is out of water.

Species: Typha sp., Arundo sp, Phragmites sp, Alternanthera sp, Panicum sp, Polygonum sp, Hydrochloa sp, Scirpus sp, Juncus sp, Eleocharis sp, Carex sp, Hydrocotyle sp, Cyperus sp, Monochoria sp, Hygrophila sp, Colocasia sp, Centella sp, Commelina sp, Ipomoea sp, Sagittaria sp, Cynodon sp, Enhydra sp, Marsilea sp

Free Floating

  • Macrophytes which float freely on the water.

Species: Salvinia sp, Lemna sp, Wolffia sp, Pistia sp, Eichhornia sp

Rooted With Floating Leaves

  • Macrophytes which are rooted in the lake bed with floating leaves.

Species: Trapa sp, Ludwigia sp, Nymphoides sp, Nymphaea sp, Brasenia sp.

Submerged

  • Macrophytes which are entirely within the water.

Species: Ceratophyllum, Vallisneria sp, Elodea sp, Cabomba sp, Hydrilla sp, Myriophyllum sp, Chara sp, Potamogeton sp, Ruppia sp, Najas sp, Ottelia sp, Aponogeton sp

Over the years, Eichhornia sp or Water Hyacinth (Kachuripana in Bengali), a globally invasive weed has posed a major problem for the lake. Their prolific growth fills up entire sections of the lake affecting the growth of other aquatic plants and making the waterbody impossible to navigate by boat. The proliferation of Water Hyacinths may also be a warning indication that the lake may be slowly transitioning from an oligotrophic water body to a eutrophic water body. Eutrophication is caused by the presence of excess nutrients in the water. Eutrophication is undesirable as it causes massive plant and algal growth, depletes the dissolved oxygen content, and affects fishes and other aquatic life forms. The excess nutrients come from the monsoon silt, human sewage waste, and leaching of fertilizers applied to the adjacent agricultural fields. It is to be remembered that the lake has a large catchment area that feeds the lake with rainwater.

Emergent species like the Hogla grass Typha sp, Nalkhagra Phragmites sp, and other tall grasses are also slowly increasing their territory, thereby diminishing the total water area of the lake. The water in the lake is alkaline and it still continues to be fit for irrigation. Turbidity is also low. 

Great Egret

Life Around The Lake

Village life around the lake is partially dependent on the lake. The main activity on the lake is fishing. There are several fishermen who catch good quantities of fish daily from the lake. At least twenty to thirty species of fish, most of them common in the Bhagirathi river, are caught in the lake using nets. To maintain navigable water routes in the lake, the fishermen community engages in clearing Water Hyacinths once every year. Farming is practiced using water from the lake for irrigation. Bathing at the ghats is also a common activity. 

In the winter months, tourism activities like picnics, boating for leisure, and hiring of boats for birdwatching, ferrying of tourists in rickshaws augment the income of the local people substantially.

Barn Swallow

Threats To The Ecosystem

Several anthropogenic factors pose a serious threat to the ecosystem of the lake. There are farmlands on the banks of the lake. Taking advantage of the low water level in winter, farming is done right on the bed of the lake in certain patches. Fertilizers and pesticides applied to the crops leach out into the lake. The presence of two large brick kilns in the vicinity is not helping either.

Picnic spots right on the bank of the lake create pollution in the form of thermocol plates and plastic waste. Noise pollution from loudspeakers in the winter months is another common problem.

Jute retting practiced during the monsoon months in certain sections of the lake is a major threat to the water quality of the lake.

A few years back, an ill-planned road connecting the island village of Idrakpur to the mainland was constructed right over the lake. The free flow of the water around the oxbow lake was thus cut off.

Another natural threat is the siltation caused in the narrow channel at the southern end which brings fresh water and fish from Bhagirathi into the lake. The character of the lake is bound to change in case the channel gets choked up in the future.

Conclusion

  Bhagirathi continues to nurture her child but it remains to be seen if we humans will take good care of her health. The migratory birds will continue to return to this wintering ground as long as “Chhariganga” remains in good health.

দুষ্টু মাটি ভ্যানিশ।

কেউ বা কারা যেন বুদ্ধি খাটিয়ে বার করেছে যে শহরে গাছ না রাখার একমাত্র ভালো উপায় খোলা মাটি না রাখা। সেই উদ্দেশ্যে সল্টলেকের নানা জায়গায় খোলা মাটির উপর চাপছে কংক্রিটের প্রলেপ। তার উপর চাপছে আধুনিক টাইলস। তাতে কার কী সুবিধা হচ্ছে জানা নেই ( কিংবা হয়তো জানা আছে)। আপনি বলছেন আমার তাতে কিসের জ্বালা? আচ্ছা তাহলে বলি।

সল্টলেকের খেলার মাঠ এবং খোলা জায়গা গুলো নিয়ে উন্নয়নের নামে যে ছেলেখেলা চলছে তার কিছু উদাহরণ দিই।

ক) খেলার মাঠের ভিতরে সুন্দর ভাবে হাঁটার এবং ছোটার ট্র্যাক করা আছে। বয়স্কদের জন্য বসার জায়গাও আছে। অনেক জায়গায় সুন্দর ভাবে বাঁধানো দ্বিতল কমিউনিটি সেন্টার ও আছে। তা সত্বেও মাঠের চার দিকে যেই খোলা মাটিতে বৃক্ষ গুলো দাঁড়িয়ে আছে সেই মাটিতে ইঁট, কংক্রিট ফেলে তার উপর টাইলস দিয়ে বাঁধিয়ে দেয়া হচ্ছে। আমফান ঝড়ে পরে যাওয়া গাছ গুলো কে সুন্দর ভাবে JCB দিয়ে তুলে ফেলে সেই জায়গা বাঁধিয়ে দেয়া চলছে (ছবি সহ প্রমাণ আছে বি কে পার্ক-এ)। যে কটা গাছ অবশিষ্ট আছে সেগুলোকে কোনো মতে দুই ফালি জায়গা ছেড়ে চার দিক দিয়ে ঢেলে দেয়া হচ্ছে কংক্রিট।

এক একটি মাঠে এই খোলা মাটির আয়তন খুব কম হবেনা। এক একটি মাঠের পরিধি তিনশো থেকে চারশো মিটার বা তারও বেশি। ট্র্যাকের ভেতর খেলার মাঠ। ট্র্যাকের এবং বাইরের পাঁচিলের মধ্যে খোলা মাটির অংশ চওড়ায় প্রায় আট ফুট এবং তা চলছে মাঠের চার ধার জুড়ে ।

বড় গাছ ছাড়াও এই জমিতে বড় গাছের চারা জন্মায়। বিভিন্ন জংলী ফুল ও ঘাস জন্মায়। সেই ফুলে এবং ঘাসে প্রজাপতি আসে। ফড়িং, ব্যাঙ এবং বিভিন্ন্য পোকা মাকড়ের দেখাও মেলে এই সব বড় গাছের নিচ দিয়ে। তাতে কী এসে যায়? আসছি তাতে।

১। অযথা মাটি বাঁধিয়ে দেওয়া পরিবেশের জন্যে খারাপ। মাটির তলার জলের পরিমাণ এমনিতেই কমে যাচ্ছে। কংক্রিটের ওপর বৃষ্টির জল মাটি চুঁইয়ে ভূগর্ভস্থ জলের স্তর অবধি পৌঁছাতে পারছে না। নেমে যাচ্ছে মাটির তলার জলের স্তর। উল্টোদিকে বৃষ্টির জল গড়িয়ে ড্রেন দিয়ে গিয়ে পৌঁছাচ্ছে নালায়। নালা গুলো ভর্তি হয়ে শহর ভেসে যাচ্ছে। শহরে বন্যা হলে ভগবানকে ডেকে লাভ নেই। ভগবান এমনিই আপনার কাজ কর্ম দেখে ছিলিম টানতে টানতে হাসছেন।

২। গাছের গোড়ায় জল এবং খাদ্য পৌঁছাতে পারছে না। অবশিষ্ট গাছ গুলো দূর্বল হয়ে পড়ছে। তাতে অবশ্য কারুর কিছু যায় আসে না। শহর ঝক ঝকে হচ্ছে সেটাই বড় কথা।

৩। কিন্তু মুশকিল আরো বাড়ছে। বড় বড় গাছের তলা পাতাঝরার সময় প্রচুর শুকনো পাতায় ভরে যায়। সেগুলো সময়ের সাথে সাথে জলে মাটিতে মিশে যায়। গাছকেও খাদ্যও জোগায়। বাঁধিয়ে দেয়া টাইলসএর ওপর পরে থাকা শুকনো পাতা ঝাড়ু মারতে রোজ ঝাড়ুদার আসবে কী ? না হলে টাইলসের ওপর সেগুলো পচে একটা পিচ্ছিল পরিবেশের সৃষ্টি করবে। শুকনো পাতার আবর্জনা ফেলা হবেই বা কোথায়?

৪। গাছের তলার জমিতে জন্মায় বিভিন্ন ঘাস এবং জংলী ছোট গাছ। বাস করে বিভিন্ন রকমের কীট-পতঙ্গ। প্রজাপতি, ফড়িং, গিরগিটি, ব্যাঙ এর ও দেখা মেলে। কংক্রিট ঢেলে দিলে এদের দেখা যে আর মিলবে না তা বলে দিতে হয় না। তখন না হয় পরের প্রজন্মকে ব্যাঙ দেখাতে (সরি, frog দেখাতে) চিড়িয়াখানায় নিয়ে যাবেন। তবে ভারসাম্যতার সূক্ষ্য সুতোর টান পড়বে পাখিদের ওপরেও। সব পাখি গাছে গাছে উড়ে শীষ দিয়ে দিয়ে ফল খায় না। অনেকে গম্ভীর ভাবে মাটির ওপর লাফিয়ে লাফিয়ে পোকাও খায়। যাকে বলে strictly নন-ভেজেটেরিয়ান। আর প্রায় সব পাখির বাচ্চাকেই শুধুমাত্র পোকাই খাওয়ানো হয়। তো আপনারা তো সামান্য পাখির বাচ্চার খাবারের জোগাড়টুকুও রাখছেন না।

৫। মাটিতে পরে থাকা বীজ থেকে প্রচুর গাছ আপনি জন্মায়। গাছের দোষ নয়, এটাই প্রকৃতির নিয়ম। সেটি আর হবার জো নেই। মাটিই নেই। সুতরাং নতুন করে পরের প্রজন্মের গাছ জন্মাবার জায়গাও নেই। আর আপনি তো আপনার বেতো শরীর নিয়ে কংক্রিট খুঁড়ে নতুন করে গাছ লাগাতে যাবেন না। মাটি থাকলে তাও দুটো বাচ্চা না হয় মাটি খুঁড়ে গাছ লাগালেও লাগাতে পারতো।

৬। পোকা শহরে কমে যাচ্ছে বলে উৎফুল্ল হবেন না। সারা পৃথিবী জুড়ে পোকা কমে যাওয়ায় সবাই খুব চিন্তিত। পোকা কমে গেলে আপনার খাবারে টান পড়তে পারে। মাথা না চুলকিয়ে ক্লাস নাইনের বায়োলজির বইটা থেকে পরাগায়ন বা পলিনেশনটা একবার ঝালিয়ে নিন। পোকা এবং আপনার খাবারের মধ্যে সম্পর্কটা মনে পড়ে যাবে।

৭। অযথা পয়সার অপচয়। টাইলস, কংক্রিট এবং ইঁট এ যেই টাকাটা খরচ হচ্ছে তা নিশ্চিত ভাবে আরো ভালো কাজে লাগানো যেতে পারে। মাঠের ভেতর কেউ টাইলসের ওপর শুতে যাবে না।

খ। এবার আসি ফুটপাথ-এ । বিভিন্ন ফুটপাথ বাঁধিয়ে দেয়া হচ্ছে। এমন ফুটপাথও বাঁধানো হচ্ছে যেখানে কস্মিনকালে কেউ ফুটপাথে হাঁটে না। তার ফলে নতুন করে গাছ লাগানোর জায়গা কমে যাচ্ছে। শুধু তাই নয়। ঝড়ে পড়ে যাওয়া বিভিন্ন গাছ বা আপনি শুকিয়ে মরে যাওয়া বিভিন্ন গাছের জায়গা গুলো কিন্তু ফাঁকাই থেকে যাচ্ছে। মানে ফাঁকা থাকছে না। তার উপর টাইলস চেপে যাচ্ছে। দেখলে আর বোঝার জো নেই যে সেই স্থানে একদিন একটা বড় গাছ দাঁড়িয়ে ছিল।

বাঁধানো ফুটপাতে যদি মানুষ না হাঁটে তবে তা কিসের কাজে লাগছে। অনেক রকম কাজে লাগছে। যেমন ছোট ষ্টল বসানো হচ্ছে। খাবারের দোকানের সামনে টেবিল চেয়ার পেতে দোকানের আয়তন বাড়ানো হচ্ছে। বিভিন্ন্য দোকানের সামনে মালের স্টক রাখা হচ্ছে। দামি গাড়ি রাস্তায় না ফেলে রেখে ফুটপাথে তুলে রাখা হচ্ছে (হ্যাঁ, ছবি আছে)। পান বিড়ির ষ্টল লাগানো হচ্ছে। বড় গাছ বাড়ির সামনে ফুটপাথে রাখার বড় হ্যাপা। ফুটপাথটা পুরো আগলে রাখে।

এর থেকেও দুঃখজনক যেই ভাবে গাছগুলোর চার ধার দিয়ে বাঁধানো হচ্ছে। এক চিলতে মাটিও ছাড়া হচ্ছে না। জল, খাদ্য এবং হাওয়া শেকড়ে কী ভাবে পৌঁছাবে ভাবার দরকার নেই। (ছবি আছে, পরে দেব)।

গ। এবার আসি খালের ধারে। সল্টলেক ও VIP রোডের মাঝে অবস্থিত খালের ধারে বেশ কিছু কিলোমিটার ধরে টানা বড় গাছ এবং ঝোপ-ঝাড়ের জঙ্গল আছে বা ছিল। যাকে বলে মনোরম পরিবেশ। জানা ছিল সেটি ফরেস্ট ডিপার্টমেন্টের আওতায়। কিন্তু বড় গাছগুলোকে কেটে, ঝোপ-ঝাড় পরিষ্কার করে বানিয়ে দেয়া হলো পার্ক। কারা যায় সেই পার্কে? কেউ না। সল্টলেকে কি পার্কের কোনো কমতি আছে? তবে এখন আলো জ্বলে এই জঙ্গলের ভেতরে এবং হাঁটবার রাস্তাও বানানো হয়ে গেছে ।

ঘ। গ্রীন-ভার্জটা ধরি এবার? সল্টলেকের প্ল্যান-এর মধ্যেই ছিল এই গ্রীন-ভার্জ। অনেকটা জায়গা জুড়ে টানা বড় গাছের জঙ্গল। উদ্দেশ্য ছিল সেগুলো অক্সিজেন দেবে এবং জীব-বৈচিত্র বজায় রাখবে। যারা এই গ্রীন-ভার্জের ধারে বাড়ি করেছিলেন তারা অবশ্যই জানতেন যে বাড়ির পাশে জঙ্গল থাকবে। এহান গ্রীন-ভার্জ ও রক্ষা পায়নি। কাটা পড়েছে বহু বড় গাছ। চাপানো হয়েছে কংক্রিট। বানানো হয়েছে পার্ক যার কোনো দরকার ছিল না। বসানো হয়েছে দোকান। কার স্বার্থে? জানা নেই।

অনেক বছর হয়ে গেলো সল্টলেকে। অনেক কিছু দেখে না দেখার ভান করে এড়িয়ে গেছি। এখনো চাইলে ঠান্ডা ঘরে বসে বা দূরে কোনো জঙ্গল এ বসে হয়তো সময় কাটিয়ে দিতে পারি। কিন্তু ভেতর থেকে খোঁচা দেয়। তাই চারিপাশে যা ঘটছে সেটা আপনারা স্বাভাবিক মেনে নেবার আগে একটুখানি লিখে ফেললাম। আপনি আমার সাথে একমত না দ্বিমত তা নিয়ে আমার মাথা ব্যাথা নেই। যেটা হচ্ছে সেটা যে ভালো হচ্ছে না তা নিয়ে আমার মনে কোনো সংশয় নেই। আস্তে আস্তে সবাই টের পাবেন। সবুর করুন।

গেটের পাশের বড় বৃক্ষটি ভ্যানিশ। মাঝে হাঁটার ট্র্যাক। ডান দিকে ছিল আটফুট চওড়া মাটি। চাপা পরে গেলো কংক্রিট-এ।
গেটের ডান দিক এবং বাঁ দিক, দুদিকের গাছ ভ্যানিশ। চেপে গেলো কংক্রিট আর টাইলস।
গাছের গোড়ায় মাটি আর নেই। গুঁড়ির গা দিয়ে বাঁধানো হয়ে গেছে সিমেন্ট এবং টাইলস দিয়ে। শিকড় খাদ্য, জল পাবে কোথা থেকে?

A Rough Guide To Planting Trees In The City

I make an effort to summarize my observations and knowledge of trees which I have gathered over the years. I feel it will help to take better decisions while planting new trees in an urban space. This guide may be applicable only to Salt Lake and adjoining regions of Kolkata (West Bengal, India) since most of my observations are from this region. As the date will suggest, this blog was written few days after the cyclone AMPHAN devastated Kolkata.

I make no claim to be an expert on trees or on biodiversity or on urban planning or on landscaping. I am not an expert on soil type. However, I love observing and interacting with nature. In this write-up, if I have missed your point of view, I apologize. I intend to periodically update this document as I keep gaining more insights and knowledge about the trees around me.

1. The Basic Conundrum

Which Trees Should I Plant? This is a question which frequently haunts us and the answer is not easy. Poor choice usually leads to disappointment. The tree may die off, may get a disease, may require too much maintenance or it may grow too tall and ultimately damage structures around. Should you plant only those trees which are tolerant to storms? The answer is NO. What would you do if a massive flood occurs and you find that the trees you selectively planted cannot withstand flood. Should you plant only those trees which can withstand flood and storm? The answer is again NO. Are you sure that a severe drought is not coming? You might find that all the trees which you selectively planted had died because they could not withstand the extreme heat. May be in near future, there will be a locust attack or a severe plant disease which will wipe out most of the trees. With so many factors at play, it is beyond the power of the human beings to fortify against all the catastrophes of the future. The answer may lie in diversity. Plant as many different species as possible, especially those which have historically thrived in your region.

You may also consider the following advice:

The first and the most important advice is to plant native trees. Native trees are trees which naturally grow and thrive in our climate and soil. They support our local biodiversity in the form of birds, bees, butterflies, mammals and small insects. These creatures in turn help to naturally disperse seeds and pollinate flowers. A thriving population of birds, insects and mammals is the best indicator of success of a plantation or the success of a forest in an urban space. The native tree species require minimal care and are usually resilient to the climate, pests and diseases. In the first few months after planting, they might need to be watered. Some hardy species do not require even that. In terms of fertilizer, you may just add a bit of compost or dung manure at the time of planting. However, you may choose not to add any fertilizer. Another problem associated with introduced species is that they sometimes become invasive. Their rapid and uncontrolled propagation makes the species invasive. Invasive species kills and suppresses the natural growth of native species. Prosopis juliflora is one such tree. In short, plant native trees if you do not want to disturb the ecological balance of your region.

The second advice is not to totally trust your aesthetics. Do not plant only those trees which bear lovely flowers or assume a pleasing shape. Like human beings, the prettiest might not be the strongest. Many fall to this deception while planting trees. I have noticed that trees have a mind of their own. They might not exactly take the shape which you want it to take. Some trees may not have the most beautiful flowers, but their dense canopy provide excellent shade. Even if you can afford an air-conditioner, the trees will still benefit you, in terms of reduced electricity bill. Trees which have large and dense canopy should be planted wherever possible.

The third advice is to be patient. Trees require a lot of time to mature and grow. It would be futile to plant only those species which grow fast without taking any other factors into consideration. Fruit trees need a long time to mature. Plant it and forget it. You may not be be the one to reap the benefits. In short, you should not plant only those fruit trees which will bear fruit in a few years time. Also do not hesitate to plant fruit trees in public spaces. You may not be able to enjoy the fruits, but you will be helping birds and also less privileged street children who might get some nutrition for free. Remember, India is a poor country.

The fourth advice is to consider the space and plant a tree appropriate for that space. Some trees need good amount of sunlight while others can survive in the shade of other trees. Planting a tree which needs a lot of sunlight, in a shade will cause it to grow to immense height and force it to take a crooked shape. Also, planting a tree which grows to enormous heights in a small space can become a recipe for disaster. The city needs big trees. They provide excellent shade and provide lot of oxygen. However, big trees should be planted on the playgrounds, open spaces, parks, wide avenues, canal sides but not in cramped urban spaces. Choosing not to plant big trees will be a big mistake.

The fifth advice is to be cautious about planting those species which have performed very poorly for your region. Performing poorly does not mean that the plant did not produce sufficient fruits or flowers. Performing poorly means that they got attacked by pests too often or they were ravaged by storms or they could not withstand the heat or got affected by the rainfall typical to your region.

The sixth advice is not to plant too many trees of the same species in a particular area. Not only does it make the landscape mundane, in the event of any disease or a catastrophe, all the trees will get equally affected. It may make more sense to plant several species together unless there is a strong evidence that a certain species does well with its own kind.

2. Role of Trees In Cities

Human beings are selfish. Cities have been built by decimating forests and precious natural landscapes. So, why should we then think about leaving some space for trees in this concrete jungle. We should for our own good. I list down few reasons why we plant trees in cities in the first place.

1. Shade. Big trees play a vital role in reducing the surface temperature of the roads and buildings around by as much as 8 degrees centigrade. It is not feasible to install air-conditioners in each and every public and private space.

2. Provides Oxygen and Alleviates Global Warming. Trees release oxygen, absorb carbon dioxide and help alleviate global warming. It should be noted that with every passing day, an increasing percentage of the global population is shifting to the cities.

3. Pollution. Leaves of the trees and the barks play a vital role is trapping air-borne dust and micro particles which are abundant in the city.

4. Nutrition. Trees in community managed spaces and private spaces have excellent scope to provide nutrition at a minimal cost.

5. Aesthetics. Trees make the city more beautiful and I do not mean only those exotic trees with bright red flowers. Every tree is a work of art. No wonder poets and authors have observed trees and have written about them.

6. Mental Well-being. That trees make you happy is now scientifically well accepted. There are scores of research highlighting this fact. Also, regular walks in a natural environment relieves stress and promotes mental well being. Check what ‘Shinrin-Yoku’ means in Japanese.

7. Biodiversity. Promotes biodiversity. Trees attract birds, bees and butterflies to the city and provides shelter and nutrition to them. Even if birds do not interest you, you should be aware that the insect population is getting decimated worldwide. No insects. No pollination. No food on the table. Got the link?

3. Wind-Firmness

Wind-firmness of a tree species is its ability to withstand heavy wind and storms without getting uprooted or severely damaged. Wind-firmness should never be the only criterion while selecting species for urban plantation, though it should play a vital role while selecting species for plantation on major roads. Similarly, it will be wrong to assume that all native species are wind-firm. There are some wonderful native tree species which attract lot of birds and insects but are not wind-firm, eg. Kalojam. Such trees should not be neglected and should be planted in the playgrounds and other similar areas.

4. Trees Which You Should Avoid Planting

Eucalyptus (Genus: Eucalyptus). This is not a native species. I have no idea why one should be planted in an urban area. They grow fast and to gigantic heights. With a thin canopy, they provide negligible shade and have a disrepute of using up the ground water. These trees are extremely prone to toppling. It does not take an AMPHAN to uproot an eucalyptus. In addition, they have no showy flowers. In terms of biodiversity, it would be wrong to say that they do not support any. In fact, some birds have been observed feeding on the nectar of its flowers. Bats also feed on its flowers.

Radhachura (Peltophorum pterocarpum): They bear lovely yellow flowers in clusters which bloom in summer. The trees have a grand canopy which provide a fine shade. The copper seedpods also look lovely. Their growth is also pretty good in this climate and they tolerate heat very well. However, the trees are extremely prone to windthrow and their huge branches break easily in the storm. It should also be remembered that Radhachura is not native to the region.

Krishnachura (Delonix regia): This tree withstands heat well and produces lovely red flowers in the peak of summer. Very few trees can beat its aesthetic value. It has been an iconic species for Salt Lake. However, I find that a lot of trees have got diseased and several Krishnachura trees have got uprooted in the storm. The tree provides moderate amount of shade. This species is not native to this region.

Small-leaved Mahagony (Swietenia mahagoni) and Large-leaved Mahagony (Swietenia macrophylla): These two are very large trees. They have huge canopies which provide good shade. However, it has been noticed that they are prone to toppling. Mahagonies often get uprooted in storms and cause road blocks and damages to building around. It should also be noted that Mahagony is not a species native to the region.

5. A Word of Caution: Tabebuia

Tabebuia (Genus: Tabebuia) in Kolkata is the rising star. It has bewitched us with its showy flowers of pink and yellow variety. It is now one of the most sought after ornamental trees for avenue plantation. Lot of new avenues are being planted with Tabebuia. Even the government nurseries are stocking it. The tree has performed well till now; even against the storm Amphan. However, it should be remembered that the tree is not native to this region. Also, at this moment most of the trees are young in the city. Who knows what the future has in store for Tabebuia. Some literature mentions that the branches are brittle. Also, the tree Tabebuia impetiginosa has performed very poorly during storms in Australia. We can plant a few but not too many.

6. Trees, Spaces And Suitability Matrix

I feel that the choosing the correct species is important in an urban space. I describe some typical urban spaces and provide some recommendation based on my personal observations. Few key information about the trees have been provided to help you choose the right species during a plantation drive. Some of the species mentioned may be easily available in the nurseries while some others can be seen germinating on the roadsides. You can also collect seeds from the wild and try germinating them at your home for plantation later at a suitable site. Please note that shrubs and climbers are not included in this list.

The list of tree species is not very short and it is intentional. I would urge you to plant as many different species as possible while keeping their appropriateness in mind.

8. Upkeep Of Urban Trees

Pruning

Pruning is often necessary for trees planted in urban spaces. However, pruning should always be done under expert guidance. Ideally, the pruning operation should be overseen by an expert appointed by the government or by the local community. Incorrect pruning by layman often results in the plant growing top-heavy canopy or a lop-sided canopy. Such trees become victim to storms easily. Also it should be kept in mind that pruning results in the death of some roots of the tree which further makes the overall tree weak.

Concretization

During concretization of pavements a sufficient space around the base of the tree should be left as it is. It allows the trunk of the tree to grow freely, allows water to seep into the soil and allows the roots to breathe. It is extremely unkind and unfair to pour concrete right up to the trunk of a tree. Also, the urban greening guidelines mentions that it is mandatory to leave space around trees during concretization. A tree which has a healthy root system has less chance of being windthrown.

9. Who Killed The Trees

In this section, I will briefly discuss the threats which the trees of the city face on a daily basis:

  1. Large native trees are often being felled in urban wild patches to make way for fancy illuminated parks. Exotic ornamental palms are being planted where large trees stood once !! This act is similar to removing the oxygen mask from a pneumonia patient and offering him a rose instead.
  2. Few homeowners are trying to utilize every inch of this city’s pavements and empty spaces for their own parking needs. Once a tree is felled by storm, the spot is quickly cleaned and filled with concrete. The pavement where once a tree stood now becomes a private parking space.
  3. Whimsical chopping of branches in front of commercial establishments. Commercial establishments in an effort to enhance their visibility are removing all the green cover in front of their office or shop.
  4. Trees are lost to developmental activities like road-widening and construction of bridges, metro-lines and metro sheds. While this may be unavoidable, compensation in nearby sites should be planned and executed before felling.
  5. Large office buildings in their effort to look clean and tidy are planting useless exotic tree species.
  6. Few homeowners in their effort to keep their premises meticulously clean are waging a war against leaf litter. They usually object to planting of trees in the vicinity of their house and sometimes force a tree to be cut down.

10. Final Word

Trees do much more than just provide us with oxygen and shade. Trees remind us of our happy childhood. Trees provide us solace in difficult times. Trees stoke our creative fires and make us happy. Let us pledge to bring back the trees to our mundane city life. Let us ensure that the trees around us live happily. This may be the key to our own happiness.

Happy planting !!

“Never say there is nothing beautiful in the world anymore. There is always something to make you wonder in the shape of a tree, the trembling of a leaf.” Albert Schweitzer
