Mayo Fire Service is urging people to act responsibly after it dealt with a significant number of gorse and bog fires in recent days.
A gorse fire in the Ballycroy National Park in west Mayo last night caused structural damage to the Claggan Mountain Coastal Trail and it burned much of the terrain.
Mayo County Council Chief Fire Officer Tony Shevlin said: "While we want everyone to enjoy the sunshine and our beautiful stunning countryside, we urge people to act responsibly."
He has advised people "not to have barbecues in open spaces, including disposable barbecues, to throw rubbish away, and to dispose of cigarettes carefully to avoid inadvertently starting a fire".
Mr Shevlin said: "We have already attended a significant number of gorse and bog fires in recent days.
He added that wildfires "can be a big strain on firefighter resources" and cautioned that "wildfires spread fast, leaving behind scorched landscapes and lost habitats".
Arising from current weather patterns a high fire risk is deemed to exist in all areas where dead grasses and shrub fuels, such as heather and gorse exist.
A fire danger notice from the Department of Agriculture, Food and the Marine remains in place until 12pm Monday.
The notice said: "Recent fire activity appears to be focussed on areas associated with active turf cutting and illegal waste dumping, and additional vigilance is warranted in these areas."
The burning of growing vegetation on uncultivated land between 1 March and 31 August each year is prohibited by law.
