About 50 firefighters are needed to extinguish the blaze near Balindalok.
After firefighters worked through the night to put out the blaze, the B9008 opened this morning between Bridge of Avenue and Glennivet.
A spokesman for the Scottish Fire and Rescue Service (SFRS) said:
“Operation Control 13 has mobilized 13 firefighting equipment and experts to the area, and about 50 firefighters have been able to withstand the blaze of grass and gorse measuring about 300 meters above sea level.
“The fire was extinguished, no injuries were reported and the crew has now left.”
The last device left at 7:26 am this morning after the stop signal arrived at 7 ፡ 15.
SFRS warned on Tuesday that wildfires are on the rise as temperatures rise in and around the region.
“Spring is a big time for wildfires in Scotland, and stored grass, leaves, twigs, and heather can spread like wildfire as a fuel,” says SFRS team leader Lynn Gow.
“However, the temperature is rising, and although it is colder than other parts of the UK, dry and hot weather is expected to continue throughout the week.”
He added: “Wildfires can destroy large areas of land and wildlife, but human behavior can greatly reduce the risk of wildfires.
“We want people to know how fast things can get out of their hands – the little outdoor lighting can spread quickly and burn for days.”
