MORE than 70 firefighters are battling 11 blazes throughout the Clarence Valley.
Superintendent Stuart Watts, district manager for the NSW Rural Fire Service said crews are concentrating on containing the fires in populated areas.
"There are numerous fires in the Clarence Valley and at this stage we are unsure of the causes," he said.
"There is one fire at Eatonsville, two at Ramornie, three in the Copmanhurst/Coaldale area, two in Jackadgery, one at Nymboida and another at Glenreagh.
"A few fires are burning remotely and it will take crews a few days to contain those blazes."
Spt Watts said the area of land destroyed by fire is currently unknown.
He added previous wet seasons and unfavourable conditions have made it difficult for landholders to conduct hazard reduction burns.
"Two previous wet seasons in the local area have ensured there is a lot of grass fuel which has been affected by frosts," he said.
"There have been a lot of fires in the Clarence Valley recently.
"We are urging residents to be cautious when thinking about starting a hazard reduction burn."
Spt Watts is encouraging landholders to seek advice from local fire brigades before conducting hazard reduction burns on their properties.
