As the hot weather continues, a Condition Red Forest Fire Danger notice has been issued at the Department of Agriculture.
Condition Red is the highest level, and is rare in Ireland.
The Department is also highlighting the extreme danger to resources and public safety arising from vegetation fires, especially gorse, and particularly near heavily-populated areas.
They're warning that upland fires can be expected to cover extensive areas and may potentially give rise to Major Emergency situations.
Fires at this time of year can also have a devastating impact on wildlife and habitats.
The Department is urging forest owners to act immediately to implement fire prevention plans, and be prepared for the likelihood of fire outbreaks on or near their property.
Landowners and manager should ensure that the use of open fires, barbeques and other potential ignition sources does not take place in forest lands or other public areas during the current heatwave.
The farming community are also asked to be vigilant using machinery around hay meadows, and refrain from the use of fire on cultivated farmland.
