Video footage and pictures have revealed the extent of the damage caused by a dramatic blaze in the Sidlaws on Friday evening.
Emergency crews from Dundee and Angus battled a two-mile fire front on Friday after hill burning got out of control.
The fire was fanned by strong winds and it spread quickly across the hillside around Craigowl, south of Glamis.
It took one and a half hours to get the flames under control and they could be seen as far away as Kirriemuir.
Fire crews from Kirriemuir, Forfar, Dundee’s Kingsway and Macalpine were all sent to tackle the incident.
Beaters were used to extinguish the flames and diggers were used to create fire breaks to try to stop the fire spreading.
Tree stumps, trunks and branches which had been collected during the clean-up of farmland next to the A92 were ablaze on Sunday night.
In response, the SFRS has issued advice to landowners and workers who are planning to carry out controlled burning across Tayside.
Gordon Pryde, the fire service’s local senior officer for Perth and Kinross, Angus and Dundee, said: “The SFRS works closely with landowners to make sure controlled burning is carried out in a safe and responsible manner.
“There are a number of steps land managers can take to help prevent wildfires, including strict adherence to the Muirburn Code, which applies to the controlled burning of heather within the permitted season.
“Additionally, anyone who is planning to carry out a controlled burn is asked to inform us by getting in touch with their local station or operations control.”
The controlled burning season in Scotland runs between October 1 and April 15 inclusively mainly to avoid harming nesting birds and some reptiles.
The SFRS is particularly concerned about fire seeping into peat bogs where it can burn uncontrollably and for a long time.
Further advice is available on the Your Safety section of the SFRS website, including the Muirburn Code.
