Oak processionary moth (OPM) caterpillars feed on the leaves of oak trees and can pose a risk to tree health when they reach high numbers. OPM also presents a risk to human and animal health due to the irritating hairs found on the caterpillars. The risks associated with OPM need to be managed. Risk management can take many forms, but the main focus is to minimise the negative impacts of the pest, and to prevent or slow the rate of spread into unaffected areas.
The OPM resource hub contains resources for owners and managers of oak trees which are or could be affected by OPM. These resources are designed to support owners and managers to understand and evaluate the risks associated with OPM and take the appropriate risk management actions. These resources are constantly under review and additional resources may be developed in response to particular needs, so it is worth re-visiting these pages to catch up on any recent developments.
