May is the time of year when the caterpillars of this invasive Moth are on the move.
The hairs of the caterpillars carry a toxin which can be a significant threat to human health, causing skin rashes, eye irritation and respiratory problems.
Find out more about Oak Processionary Moth on the Forestry Commission Website.
If you come across the caterpillars or their webbed nests please do not touch them and keep children and pets away. Report any sightings to the park office on 0300 061 2200.
