A heath fire in Surrey which started on Friday could continue to burn for several days, fire officers have said.
Thick smoke could be seen nearly 10 miles to the north on Saturday
Russell Pearson, deputy chief fire officer, said the incident was one of the largest in Surrey in recent years.
About 40 firefighters are continuing to tackle the blaze at the National Nature Reserve at Thursley Common.
It was brought under control on Saturday but some areas of undergrowth are still burning. Fifteen firefighting appliances are also at the scene.
The latest estimates are that about 60% of the 400-acre National Nature Reserve has been scorched by the blaze.
Mr Pearson said: "Naturally, large fires such as this can have a huge impact on our resources but we have plans in place to ensure we are able to work with partners and other fire and rescue services to maintain the appropriate response."
