The fire which had erupted around 2.00 pm today, had destroyed around 25 acres of the reserve.
The rapidly spreading blaze is close to a row of estate houses, while a network of high tension power lines have also been destroyed in the fire.
The dry weather conditions in the central hills and the strong winds is causing the fire to spread more rapidly.
It is suspected that some party may have deliberately set fire to the forest, while the police have informed the estate authorities to take measures to douse the fire.
