The upper reaches of Munnar have been experiencing temperatures below 00 C since the start of the month, which is unusual, and mercury dropped to -40 C after a decade in the region. Munnar Wildlife Warden Lakshmi R. told The Hindu on Saturday that vast areas of grasslands in the ENP had dried up.
She said it was a matter of concern as the area would turn fire-prone well before the drought season. She said Pampadumchola was experiencing sub-zero temperature continuously and mercury dropped to -40 C there.
Widespread damage
“Normally, temperature will rise after one or two days and the damage to the flora will be limited. However, this time the damage is widespread,” she said adding a field study would be conducted to analyse the effect of climate change in the region. Rajamala, one of the main areas where neelakurinji blossomed last year after 12 years, was inside the ENP. The August floods had damaged buds and flowers and its effect would also be studied, she added.The germination period of neelakurinji had just started and it was being analysed to learn the effect of the floods on the flora. The changes in climate conditions were clearly evident in the Western Ghats as its eastern side formed part of rain shadow areas.
Ms. Lakshmi said controlled burning had already been done on 600 hectares of grasslands and new tender grass appeared with the winter season. It might not immediately cause any shortage of fodder for the fauna, including the Nilgiri tahr, she said. However, a drought situation much before the advent of the summer season raised concerns of wildfires. If the situation continued, fodder could be in short supply too, she added.
The changes in the climatic conditions and its effect on the flora and fauna would be studied and recorded for management purposes, she added.
