Archaeological sites and monuments known at the time of the compilation of the Record of Monuments and Places established under section 12 of the National Monuments (Amendment) Act, 1994, have been included in the RMP and are protected by the provisions of section 12, which require that two months advance written notice of proposed works at or in relation to site or monument be given. Newly discovered archaeological sites or monuments will be included in future updates of the RMP but, if necessary, they can be afforded protection in the interim by entry in the Register of Historic Monuments under section 5 of the National Monuments (Amendment) Act, 1987, which imposes similar obligations of notification. If necessary, and where there is a perceived to be an immediate threat to a site, a temporary preservation order or full preservation order can be made under the National Monuments Acts. In addition, there are a number of other measures in place which are aimed at safeguarding the archaeological heritage from the threats posed by land use changes. Among these are referral by planning authorities of development applications to my Department for comments and recommendations where the proposed development may impact on archaeological sites and monuments; similar referral process by the Department of the Marine and Natural Resources in relation to forestry and marine development applications; a code of practice is in place with the National Roads Authority dealing with the archaeological implications of major road projects and other similar codes are being discussed with other development sectors and the REPS scheme operated by the Department of Agriculture, Food and Rural Development which requires that impacts on archaeological sites and monuments be avoided has over 40,000 participating farmers.
