The Department of Environment, Food and Agriculture is asking people to take care in plantations after Storm Isha.
It says it's aware of a large tree toppled and hung up near a car park at Archallagan - foresters have taped off the area and are asking people to keep clear.
DEFA says it's also expecting more damage over the next few days as more bad weather blows in.
It says people should exercise caution when walking in woodlands.
