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
