Coillte and Monaghan County Council are working to manage non-licenced vendors trading in Rossmore Park.
Currently, two vendors have permits to operate their business within the Monaghan town forest.
However, concern was raised at a recent Monaghan MD meeting of others operating without a licence and not providing bins for rubbish.
In a statement to Shannonside Northern Sound News, Coillte said it's aware of an issue regarding non-licenced vendors in the park and are working closely with the local authorities to manage it.
