A Nature Reserve is an area of importance to wildlife, which is protected under Ministerial order. Most are owned by the State. However, some are owned by organisations or private landowners, and persons interested in acquiring statutory protection for their lands can seek advice on this matter from the Department.

2021 NPWS report notes that limited details of each reserve are available on https://www.npws.ie/nature-reserves. Do NPWS have management plans for the state owned sites? Are there obligations on private owners to publish management plans?
