Who exactly lives in Pitchandikulam Forest? We’ve met (we’re pretty sure) all the human inhabitants, but what about our mammal brethren? Starting in August and armed with a barrage of cameras, our research team set out to conduct the first camera trap study in our area of Tamil Nadu, in order to better understand which species are currently living here with us.
A camera trap system is especially useful for estimating populations of nocturnal, more ‘shy’ mammals. As in every forest ecosystem, the wildlife population is constantly changing from one day to the next, and so the first step in order to estimate best where to put the cameras was to conduct a sign survey – walking the forest in search of evidence like pellets, footprints and droppings. The team readily identified the presence of carnivores such as mongoose, civet cat and jungle cat, and the cameras were soon set up on trees 50cm from the ground, pointing at the most promising areas.
Three camera traps were operational for 24 hours a day over a period of 37 days, and they took 137 photographs.
Below is a table of the ten species we identified. The most common species recorded was the Asian Palm Civet (40.9 %) followed by the Small Indian Civet (16.8%), Grey mongoose (10.9%), Indian Crested Porcupine (8.8%), Jungle Cat (8%), Black naped Hare (6.6 %), Chital (4.4%). The Golden Jackal and Bonnet Macaque were captured twice (1.5%).
Most excitingly, we recorded on camera a Rusty-Spotted Cat (prionailurus rubiginosus), which is in the “Near Threatened” category on the IUCN Red List of Threatened Species. This is the first time that this mammal has been sighted on the Coromandel Coast.
Results of the ten species documented are as follows, with the number of recorded sightings over the survey period on the left:

We are interested to talk to interested people to help with wildlife and botanical documentation and surveying. If you would like to know more about our work or volunteer for one of our forthcoming projects, please get in touch with Dr Bubesh Guptha.
