The garda helicopter was called in to assist fire services in tackling a number of gorse fires in Co Galway.
The worst-affected areas are near Spiddal and Moycullen.
Firefighters tried to keep a fire near Spiddal under control, but efforts were hampered by changing wind direction.
A number of other units attended a gorse and forest fire near Moycullen, which caused traffic problems on the road between Moycullen and Spiddal.
The fire services have dealt with a number of gorse fires throughout the county in recent days.
No houses are in danger at present, but people living near bog lands or areas of gorse are being urged to be vigilant.
