Tree list at Anna University

Led my first tree walk for Nizhal. Meaning, I was supposed to be the "resource person" as Shoba so sweetly puts it, spreading awareness about these trees! I went armed with my iPad. Why? Loaded on it was the Nizhal Siemens Gandhinagar Tree Guide, with more than 40 common trees of Chennai (all present in Gandhinagar, Adyar) identified via their fruit, flower, leaf or pod!

I used it successfully to identify the Mimusops elengi or bullet wood tree. I was very pleased at the fact that I was able to identify all these trees below that we found on our one hour walk. I would not have been able to do this about a year ago...probably only about five. Working at the PWD park and going for Nizhal's tree walks have really helped.

There were about 20 students of the college from the Youth Red Cross who came along with me. There were two other resource persons Latha and Yamini, who went to other parts of the large and green campus. These were the trees seen and talked about, along the western driveway just inside the main gate. This is the path I took.

1. Mast tree (false ashoka) - identified by its profile
2. Copper pod - pods and yellow flowers
3. Gulmohar - smooth bark, small leaves, large pods
4. Pongamia - with the leaf galls, a hardy local tree
5. Rain tree - there were a few flowers. told them about the insects that make the "rain", and the thoongu moonji look of the leaves in the evening.
6. Neem - the wonder tree, that everyone knew.
7. Tabebuia - there are massive specimens that line the inner walls of the campus.
8. Peepul - the fig wasp story told.
9. Cassia yellow
10. Cassia pink
11. Bauhinia - we discussed the leaf shape, and there was some lovely purple blloms too.
12. Mimusops elengi - this is the one that we went step by step using the guide (since I could not identify it straight off).
13. Palmyra - TN state tree
14. Banyan - a nice large specimen
15. False rudraksh - hairy leaves and black rudraksh-like seeds.
16. Nuna - the bark was a giveaway
17. Java olive - with their palmate leaves and characteristic seed pods
18. Subabul - the "conflict" tree, that does not allow other species to thrive, with the easily identifiable seed pods.
19. Fishtail palm
20. Golden cane palm

The Tree Guide is a handy tool for Chennai. It can be loaded on a smart phone or laptop and works well. Would you like a copy? Post a comment below, or fill in the feedback form at Nizhal's contact page. It costs Rs 150.

"My husband and other animals — Take me home"

The Hindu : Life & Style / Metroplus : My husband and other animals — Take me home

Rom's mother always said that a toad or two under the kitchen sink was all one needed to keep the house clean of cockroaches. Guess what, much like everything else on our crazy farm, toads just colonised our house en masse, in a scene not different from the tree frog invasion. Like walking on a forest path, every night I had to watch where I put my foot in the house. No matter how careful I was, the magnificently-sized, sticky toad turds just jumped out, and stuck themselves to the soles of my feet! Forgetting whatever I was doing, I was forced to hobble off to wash the offending black ‘toad-gum' immediately. After a few such nightly episodes, I threw the toads out of the house, but fearlessly they returned to face my wrath.

I collected them in a plastic container and took them to the edge of the front yard, about 250 metres away, and released them. They had the temerity to return. I marked them (identification), spun the container round and round (disorientation, I thought), took them on a long detour around the farm (confusing, I imagined) before letting them go 500 metres away. There! I proclaimed in smug confidence. They were back in 25 hours.

By now, the blighters knew what was in store when the she-ogre came for them. They squeaked in distress, pissed copiously in fright, and tried to evade capture. I almost relented, but now curiosity drove me on. 750 metres. Back in 30 hours. That's a fairly long distance for small creatures to navigate. Spun the bottle, took them down the long dirt path, across the road, into the jungle and let them go by a puddle. One km away. Success? While I succeeded in chasing them out of the house, I found a couple with tell-tale markings in the outdoor planters. Now I can't tell if all of them made it back or only some did. What do other creatures do when taken far from home? Here are some interesting facts I unearthed.

In Namibia, out of eleven marked leopards that were moved 800 very long km, six returned home over a period of five to 28 months. Let me put it this way: if these cats had been taken from Chennai and released somewhere a bit north of Goa, they were able to walk right back! In the U.S., most of the 34 black bears that were moved about 200 km from their home territories returned successfully. In India, an elephant translocated from the Terai to Buxa Tiger Reserve, a distance of about 250 km, returned in less than 2 months. Salt water crocodiles in Australia were shown to home back after being moved 400 km. Put me in Bangalore, and I'm lost immediately.

However, the distance record for homing is held by seabirds such as albatrosses and shearwaters. An albatross taken from an island in the central Pacific and released about 6500 km away in the Philippines returned in a month, two others returned from Washington State, 5,000 km away.

It is not just the larger animals who have this amazing skill. In the U.K., bumblebees found their way home after being randomly dropped off 13 km from their hives. So what's a km to a toad, eh?

The fact that these animals, birds and insects return home is well-documented. But, how do they find their way through unfamiliar terrain over long distances?

Since these animals are frequently moved in covered vehicles on the outward journey (or a closed plastic container), it is unlikely they remember the route. In many cases, the animals return journey did not follow the road they were taken out on at all, but instead, took a more direct path homewards. So, how do they do it?

Ecosystems of Madras in need of some TLC

The last week has seen two articles in the Chennai Times of India on the neglect and abuse of our city's natural spaces.

The Nanmangalam Reserve Forest

A tiger spotted at Bharatpur

Bharatpur is home to the Keoladeo bird sanctuary. The article below was sent to the MNS e-group, and I was immediately transported back in time to the winter adventures of the Mad Madrasis, our 53 hour train ride to get to Bharatpur, and our daily cycling (mis)adventures at the park.

And now a tiger, identified as T7 has been spotted on camera (but not in person), devouring a boar, and suspected at having killed a nilgai as well. He seems to be a maverick tiger, sort of lone ranger, outlaw type, having made his way from Ranthambhore.

The Hindu article.

The male tiger that intruded into the Keoladeo National Park bird sanctuary near Bharatpur in Rajasthan this past Sunday is seemingly enjoying his stay and is in no hurry to leave. The animal, now confirmed as T-7 of Ranthambhore National Park, which announced his arrival in Keoladeo with the killing of a blue bull, has over the past two days hunted a wild boar and a calf of feral cattle and fed on the former ignoring the calf. Though the bird sanctuary staff has been keeping a vigil, the tiger has not made an appearance before the humans so far.

“The tiger continues to be in Keoladar area of the sanctuary where the grass is standing tall. No one could spot it so far despite a strict vigil. However, we have now with us a set of 25 photographs of the animal eating the wild boar, taken with the help of a trap camera,” informed Anoop K.R., Field Director of the National Park, speaking from Bharatpur on Friday.

“The tiger seemingly consumed the wild boar fully though some of the photographs show a hyena in the background,” he said.

The tiger was on the run for the past fortnight after attacking and injuring over half a dozen persons at Mathura in neighbouring Uttar Pradesh. Curiously this is the same tiger, estimated to be around four years old, which had badly mauled a range officer in a village on the periphery of Ranthambhore National Park a month back. Even prior to this, T-7 has been shuttling between Ranthambhore Park and the neighbouring sanctuary of Kailadevi before choosing the long haul to the Rajasthan-UP border. Experts are of the view that going by its past behaviour the animal is not to remain in the 29 sq km area of the sanctuary for long.

“I have watched this tiger closely. He is not to stop here for long,” said Dharmendra Khandal, Director of Tiger Watch at Ranthambhore. Dr. Khandal, who confirmed the animal in the picture as T-7, said the authorities should devise a plan for shifting it to any tiger sanctuary, preferably not Sariska. He was dismissive of taking it back to Ranthambhore or Kailadevi as the former was already “saturated for tigers” and the latter did not have an adequate prey base.

“We can exchange it for a tigress from Madhya Pradesh. The animal can be shifted to Kuno, Panna or Kanha. This could be a gene pool exchange which will benefit the tigers from both the States,” he argued.

There have been reports in local newspapers about the Rajasthan forest authorities planning to shift T-7 to Sariska to join the already existing five tigers, relocated from Ranthambhore. “There are already two male tigers in Sariska now and another male is not of any additional relevance,” he pointed out.

There is reason for the authorities at Van Bhavan, the Forest Department headquarters here, and at Keoladeo National Park to worry as T-7 is a tiger with a past. The young cat has attacked a good number of people and has seemingly lost its fear of human beings. Keoladeo is a bird sanctuary where the visitors normally move either on foot or on bicycles and cycle rickshaws. “T-7 is no more afraid of the presence of humans. That is not going to help much as it has a history of attacking humans,” Dr. Khandal observed.

Its travelled a fair distance!
