Volunteer fire fighters were called to a fire at Clifton Grove just before 10am on Wednesday morning due to burning tree roots near Ophir Road.
Rural Fire Service Canobolas Zone group captain and Clifton Grove brigade representative Geoff Selwood said the warmer weather and yesterday's strong winds caused soil to dry out and the previously burnt stumps to reignite.
The fire came after the state of emergency for the the Canbolas Zone was lifted on Wednesday morning.
Canobolas Zone Superintendent David Hoadley said one of the strike teams that was on standby during Tuesday's high danger period was sent to help at Tamworth on Tuesday night.
The other strike team, the Mid-Lachan Valley team was sent home.
Superintendent Hoadley said he wanted to thank all the brigades and volunteers from the Canobolas Zone and Mid-Lachlan Valley team for their readiness on Tuesday.
In regard to Wednesday's small fire, Mr Selwood said it was caused by willows that were burnt by the Clifton Grove brigade two and a half to three months ago.
He said because the roots were encrusted in dirt they had continued to smolder underground but the conditions helped them reignite.
Mr Selwood said the willows were pulled out of Summer Hill Creek as part of an environmental clean-up program.
He said it was a good reminder to people about why the Rural Fire Service advises against burning tree stumps, particularly eucalyptus stumps in spring and summer.
"Logs underground will burn underground," he said.
"They can burn underground for up to three years."
Mr Selwood said when they got to the site on Wednesday morning, the ground was "quite hot" but the property owner was planning to bring in some heavy earth moving equipment to spread out the soil so the volunteer fire fighters could extinguish the fire for good.
