Members of the public intending to visit forests and other recreational sites are reminded to adhere to regulations introduced to limit the spread of Covid-19. Vehicles must not be parked at site entrances or impede emergency service access to forest roads. Visitors should not use barbeques or open fires at any stage.
BE PREPARED. BE VIGILANT. STAMP OUT FOREST FIRES
Advice to the General Public/Forest Visitors
Members of the public and visitors to recreational areas should cooperate with all requests regarding fire safety, obey all relevant bye-laws and be considerate in parking vehicles so as not to impede access by emergency vehicles.
Where fire outbreaks occur at or near recreational areas the following actions should be taken by visitors in the interests of safety.
1. Do not light fires in and around forests or open land.
2. Do not attempt to intervene or fight fires under any circumstances.
3. Gather all family/group members and move to a safe fuel-free location such as a car
park, upwind of the fire.
4. Telephone Fire and Rescue Services via 112 and report the fire and its location.
