It is also possible that if you have a very high baseline of rain, as Kerala does, a decrease in rain of 10 or 20 percent may not affect vegetation that much. But the reason could also be that we have very poor observation and recording sites in India, compared with the [United States] or other Western countries; we have very few long-term monitoring posts."
One permanent study site is a 50-hectare plot in the Nilgiri Hills, part of the Western Ghats in the state of Tamil Nadu. Professor R Sukumar has been studying the vegetation changes on this plot for the past 25 years as part of his research into ecology and climate change.
In particular, he has observed how changes can pave the way for invasive species to dominate a landscape: A drought in 2001 made the area dry and fire-prone. Large fires in 2002 in the Western Ghats then burned up the grasses in the dry deciduous forests of the area.
