Crafting India’s Landscapes!

(An extreme view of tree plantation & a small example of practice)

Its that time of the year when civic and nature organisations in India wake up from their slumber and begin to consider tree-planting yet again. Though this is an annual affair, strangely India’s forest cover and biomass doesn’t seem to improve even where these activities are being carried out.

Typically, tree plantation begins with the collection of whatever dismal fare in saplings the forest department is willing to provide, followed by the desultory digging of holes and careless planting of trees. This activity, concluded in a couple of days in the early monsoon, will be followed by a relapse into torpor.  The final act is, of course, the appearance of a plague of self-publicised reports in the papers.

Over the next few months though, the thousands of saplings, thoughtlessly planted, are exposed to the harsh Indian environment accompanied by the complete neglect by the tree-planters.  The subsequent perishing of the year’s plantation by the end of the next summer (except for the miniscule few which by God’s grace actually manage to survive) should come as no surprise. And in the hallowed traditions of Hindu religious ideology, the kaal-chakra turns to bring us back to tree-planting season again. Paradoxically, all of us feel good having participated in a worthwhile activity even though it is conducted so abominably.

Not all tree-planting is conducted this way. People plant carefully selected saplings to enhance their gardens and backyards. Some corporates do succeed in giving strikingly good tree-scapes and gardens to their campuses. Children all over carry out this activity with the single-minded intensity of play. To them it is something well worth doing. A few civic organisations do exceptionally fine jobs of restoring plant cover and biodiversity to their favourite haunts. But these are a drop in the ocean when compared to the morass of carelessly contrived tree-plantation schemes in our country. Not convinced by my assertion? Please see the text box below :

Unhealthy trends in tree plantation

I am sure you would have your own “war stories” to tell.

Its not that we are cultural “philistines” as far as trees and plants are concerned.

Hindu culture gives trees (or plants) an importance of their own. Planting a tree is said to be more fruitful than having a hundred sons. A number of trees figure in our pantheon of objects worthy of worship – the Peepul Tree (Ficus religiosa) and Banyan (Ficus benghalensis) come immediately to mind. The Kalpavrisksh which fulfils the wishes of all, the Bo tree under which the Buddha gained enlightenment, the Aak (Calotropis spp) tree under which Emperor Akbar was born are some examples of trees in our culture. Fragrant flowers are offered to our Gods in obeisance. Certain plants are associated with our deities – the “krishna” and “laxmi” varieties of Tulasi (Ocimum sanctum) and the Lord Dattatreya’s fondness for the Umbar or Audumbar (Ficus racemosa) spring to mind.

Yet, we tend to approach tree-plantation with less finesse than a three year old child.

Perhaps it is semantics.  The term “tree plantation” implies that our job is just to plant – it’s nature’s business to do the rest. The truth is, if we want to really make a difference, the business we should be in is “growing trees” not “planting trees”.  That implies a whole lot more than partial burial of an juvenile plant in unprepared ground. The successful planting and growing of trees is not a rapid paced activity but takes an enormous amount of time and effort. Accordingly, there is a need for  thinking deliberately, planning and careful preparation before we get down to the plantation which is just one event in the long process of growing trees.

Maybe the  reason is selfishness. In this materialistic world, there is nothing to be gained by labouring for unborn generations. In such a view point, tree plantation would be meritorious only as a means for acclaim (for publicity and public adulation), getting rich (through corruption or by marketing one’s products) or as an indicator of performance (X planted more trees in his tenure than Y).

"Monocultures are ecological deserts. Tree plantations are not forests." (click image to learn more).

Another malaise in tree-plantation is mono-culture. It could be that most people do not realise that the planting trees of a single species, termed as mono-culture, is harmful. But the gaurdians of Indian forests should know. Invasive trees take away more from our environment than their successful propagation. Yet it is the bureaucratic forces which have championed the cause of ecologically harmful  exotic trees which grow quickly  –  such as Australian Acacia (Acacia auriculiformis), Kubabul (Leucaena leucocephala) or the various forms of Eucalyptus – or even worse, the highly poisonous Jatropha curcas, purportedly for “bio-diesel”.

It is the banal attitude towards tree plantation which reduces such a worthy activity to a pedestrian one that irks me greatly.

The highest form of appreciating nature is in growing exotic trees - Alexander von Humboldt. (Public domain image)

A great scientist of the nineteenth century, Alexander von Humboldt stated that the highest form of nature worship was engaging in one or all of the following :

  • Writing Nature poetry.
  • Painting landscapes.
  • The rearing and planting of exotic trees.

I find that I agree broadly with Humboldt. This blog showcases some of the finest nature poetry. You can read about Frederic Edwin Church and his “Heart of the Andes” over here. I agree that growing of plants is a really worthy activity but I would replace the word “exotic” with the adjective “right”.

As far as growing trees is concerned, my own humble opinion can be summed up as :

Tree-planting is a craft. We should be “tree-smiths” – carefully crafting the environment in the manner that we make a Japanese garden, with each tree carefully chosen for effect, harmony, utility, importance, i.e. for a purpose. Growing trees is not meant to be hedonistic or banal. It must be done spiritually – a kind of zen activity.  It must be done to completeness. And the result must be healthy trees that give us the benefits we hoped for and more.

For that, we really need to know and love our trees. I love to recall the feel of the bark and leaves of the Banyan, the smell of flowers of the Neem (Azadiractha indica) or the crushed leaves of the Kadi Patta (Murraya koenigii) , the visual extravaganza that the Laburnum (Cassia fistula) provides in summer. Once we get a feeling of love and appreciation of trees, then and then alone can we make quality choices about the best or most appropriate shrub or tree to be chosen for a spot.

If you want to attract birds, the Umber or wild fig (Ficus racemosa) is your best bet. If you want a red avenue in summer, it’s the exotic Gulmohar (Delonix regia) you need to choose. For lots of shade with few trees, opt for the Rain tree (Albizia saman).  You can never go wrong by planting Babul (Acacia nilotica) for the welfare of the poorest of the poor – it’s firewood has the highest calorific value.

Babul has the highest calorific value of Indian trees and is consequently of great importance to the common man. (Image credit : Dinesh Valke, under CC-BY-NC-ND)

On the other hand, if you don’t do the learning yourself and rely on the “experts”, expect to find that you have created yet another tree-covered barren landscapes by using Kubabul provided by the Forest Department or orchards of stunted Jatropha if you believe the agro-industrialists.

The real challenge in growing trees is not planting trees but keeping them alive. We can tackle this is many ways.

One is commitment. Choose carefully based on what level of care you can commit. In other words,

“Bite off only what you can chew”

or

“Cut your coat to suit your cloth”.

Our children of the Painted Storks Nature Club wanted to plant trees in the Sarvatra Bird Sanctuary. But it is not possible (or realistic to expect) for the children to come  and water the plants since the sanctuary extends over many acres, has lonely corners, and very little access to water. So we decided to plant in close vicinity of the Middle Lake Garden which is frequented by the children, where water is nearby and where the gardeners can help water these plants.

The Lake Garden provided little scope for useful addition, so we decided to plant some trees and bushes around the CME Lake Mandir where except for a Tulsi plant (Ocimum sanctum var krishna) in front and a Tamarind tree (Tamarindus indica) above the temple, no other plants were present. It is just 30 meters from the garden and on the lakeshore itself.

We chose our plants carefully. Since we were planting around the mandir (temple), the emphasis was given to shrubs with bright flowers or having perfumed flowers. We tried to choose those which are commonly used for worship in Maharashtra. We also decided to plant three small-statured trees which would highlight the mandir’s background. We chose well-developed saplings for plantation which were sturdy enough to survive (unintentional) neglect and which already had some flowers so as to enthuse the children and give them a foretaste of how the garden would look. It was more expensive but worth it.

Children plant a shrub with rapt concentration.

The Painted Storks planted the following shrubs on the side of the temple :

* “Juhi” (Jasminum auriculatum)
* “Mogra” or “Madanbaan” (Jasminum sambac)
* “Tagar” or Crepe Jasmine (Tabernaemontana coronaria)
* “Anant” (Gardenia jasminoides)
* Red Hibiscus (Hibiscus rosa-sinensis)
* “Raj Chameli” (Jasminum nitidum)
* “Chameli” (Jasminum flexile)
* “Zai” (Jasminum officinalis)
* “Sarpagandha” (Rauwolfia serpentina), a medicinal plant.

Behind the temple we planted three saplings of small trees having beautiful flowers :
* “Parijaat” (Nyctanthes arbor-tristis).
* “Savni” or Crepe Myrtle (Lagerstroemia indica).
* “Sonchafa” or “Champak” (Michelia champaca).

The first tree being planted - a "Parijaat".

That is it – exactly twelve plants, but well chosen, well planted and well-located. What do you think are the odds of survival of these twelve than the desultory planting of many more? And when they do survive which will give the better effect?

One could of course say, don’t confuse gardening with tree-plantation, but the principles are the same.

Problems and dilemmas will arise in this activity, as it does in all of mankind’s ventures. The most important one would that as to how to water the plants regularly. In my opinion, this would be the most difficult of all tasks associated with nurturing trees. When we know that we cannot come often to water the plants, should we not plant?

We could choose to plant drought resistant native species such as Neem and Babul. We could jury-rig  drip irrigation with plastic bottles and tubes which would need less water and give a longer effect. We could mulch the saplings – the mulch helps retain the water, reduces erosion, suppresses weed growth and seed germination and adds to the fertility over time. We could water in the evening where our water loss due to evaporation will reduce. We could choose to come at a fixed intervals as per our convenience – say once a fortnight or month, to water the plants accepting the triage due to the environment. We could plant hardy two-three year old saplings rather than very small saplings.

By applying our mind, and by matching our effort to our thought, we can increase the chances of survival of the trees.

If I were to plant a few hectares of arid area in Maharashtra, for example, I would choose native species such as Babul and Ber  (Zizyphus jujuba) for the general backdrop, add a few Ficus to form the focal points and plant many interesting but scarce trees. A few Agaves would help prevent soil erosion in the monsoon run off along with some simple landscaping, a few legumes would help improve the soil condition. There would also be a few creepers, many shrubs (both perennial and annual) and definitely useful grasses and bamboo. Maybe a few exotic Gliricidia trees to provide ready-made green manure for the caretakers. Amidst these, a few trees or shrubs carefully selected to provide all kinds of resources (nectar, food, shelter, nesting etc) to the typical biodiversity of that place.

That’s all I can come up with off the cuff. But in reality, the tree plantation scheme for this otherwise hypothetical scheme would be worked out carefully in much greater detail and perhaps even plotted graphically on a map. The location, aim, species available would all be considered. A planting schedule over two-three years would be considered. The civil engineering works would be restricted to a bare minimum. Nothing more than a fence, water tank or supply. A shed for the forest guard and perhaps minimal amenities in a place under a shade tree where the nature-lovers can sit, rest, enjoy nature, have their meal etc.

However, I would expect the record-keeping and science to be top class. None of the careless generalities thrown in by so-called experts. The practice of science in even such a routine activity as tree-plantation should be second to none.

That then is my view of tree-planting…

Let’s not just plant trees, let’s craft Nature.

A Decorative Beetle

12 July 2009


Calothyrza margaritifera - a Cerambycid beetle recently found in Pen.

Calothyrza margaritifera - a Cerambycid beetle recently found in Pen.

On a afternoon in early July, at Vavoshi near Pen, my father-in-law, Mr Nandan Kalbag spotted an intriguing beetle in black and white. It resembled a stylised Guy Fawkes mask of the kind that I remember seeing in ‘V for Vendetta‘. It was perched on a hanging flower-vase and was motionless. It stayed there awhile and after a couple of hours it was gone.

One of the big advantages of being a son-in-law of a man keenly interested in the natural world around him is a steady stream of images and anecdotes which permit me to vicariously enjoy those moments with him. In course of time, the image came to me, was bunged onto the InsectIndia yahoo-group. There it was picked up by a friend and forwarded to a Dr Hemant Ghate of the Zoology Dept of Modern College in Pune, a man desperately keen on beetles. After consulting with Dan Heffern, an American engineer turned coleopterist, a verdict was delivered – the culprit was identified as Calothyrza margaritifera which was described by Westwood in 1848.

Common names are a luxury available to enthusiasts of mammals, birds, butterflies, a few reptiles and amphibians. In the world of arthropods, there are very few common names. Calothyrza margaritifera – the name meant nothing to me. I don’t really know much about beetles – I am quite prone to mis-spelling them too; I forget they are ‘beetles’ not ‘beatles’. India has no recent handbooks on beetles for the amateur. It took a little patient digging online to find out a little more about this curious insect.

Calothyrza margaritifera is a longicorn or long-horned beetle; it belongs to the family Cerambycidae. Most but not all cerambycids have antennae longer than their bodies. These beetles are wood-borers and some are economically significant pests. Some small cerambycids mimic ants, wasps and bees. A member of this beetle family is considered to be the largest insect in existence today.

C. margaritifera belongs to the tribe Phrynetini of the subfamily Lamiinae. The beetle volumes of the Fauna of British India of the early twentieth century vintage are the only tomes available to the amateur naturalist of India. Unfortunately Charles Joseph Gahan, the author of the Cerambycidae section only wrote one volume which unfortunately excludes the Lamiinae, those taxa being reserved for the never written second Volume.

The known range of C. margaritifera embraces the Central Himalayas of India and Nepal, and extends across Myanmar to Thailand. The discovery of this beetle in Raigad district of Maharashtra is then an important range extension. Fortunately, the species has a very distinct look so that, strictly speaking, a specimen may not be needed to record the find.

Like most picturesque long-horned beetles, Calothyrza margaritifera demands a substantial price on the international specimen trade – prices typically range from ten to 35 dollars each. Most Calothyrza specimens show Thailand as their area of origin. One may think that the Biological Diversity Act of 2002 as amended may protect Indian beetles but there is ample evidence to the contrary on the internet, this site being one such example. Single Calothyrza margaritifera specimens, and occasionally pairs appear for sale in insect catalogues and sometimes on E-Bay!

We are often reminded of the need to preserve and protect our biodiversity by stories of how such and such organism s being investigated for new science, fresh discoveries and path-breaking insights. It may interest you to know that Calothyrza margaritifera is one of those. In this case, the vivid white of the beetle cuticle is being investigated at the nano-technological level. The vivid whiteness of the beetle’s cuticle is not the result of a hue but rather the nano-structure of pill-shaped chitin growths. The abstract of the paper, presented in a symposium on ‘Bioinspired and biointegrated materials as new frontiers for nanomaterials’ (Symposum M) on 10 Jun 2009 at 12:05 hrs this year in Strasbourg, can be found here.

What worries me most is that there are hundreds of such delicious scientific curiosities waiting to be discovered in our jungles which may never come into existence before the forests and their associated biodiversity are lot forever.
