Tywyn, Aberffraw: This area comprises a large mobile sand dune system. Over winter, cattle are grazed under a carefully managed prescription to enhance the habitat and in conjunction with CCW gorse has been controlled. Regular access is provided for educational purposes (schools / universities) as well as to the Environment Agency for purposes such as monitoring of dip wells.
Y Werthyr / Pandy Treban: This is a good example of a mesotrophic valley mire or fen with high water table. Plants found here are typical of this type of wetland such as bogbean, marsh cinquefoil and the uncommon greater spearwort. It includes marshy grassland and scrub. This mix of habitats is important for much of the wildlife including many invertebrates and birds. It is grazed by an Estate tenant in conjunction with advice from CCW.
Ty Croes: Important for coastal heathland, coastal grassland and wet flushes which support chough, marsh fritillary butterfly, sea samphire, allseed and petty whin. Areas of heathland have been reduced by nearly 50% on Anglesey since 1940 and the remaining fragments are important features of the coastal landscape.
Penrhynoed Llangadwaladr (Bodorgan Head): Here there are a number of nationally scarce vascular plants such as dune fescue, sea storks-bill, golden samphire, sea spurge and portland spurve. Also it has a complex mosaic of exposed rocky coast, grassland, sand dune and dune grassland. This mix is important for varied wildlife, particularly breeding birds. Sea wormwood also grows here in one of its few North Wales locations.
Llyn Padrig: This is a mesotrophic wetland and contains autumnal water starwort, a rare water plant. It includes marshy grassland, a lake and an area of scrub and wet woodland. This habitat helps to support several nationally scarce water plants such as hair-like-pondweed, waterwort and slender spike-rush. Bangor University are using this area for vital and groundbreaking research on carbon fixing.
AONB: Much of the Estate land falls within AONB, which is predominantly a coastal designation and administered by Anglesey County Council. The aim is to ensure Anglesey's special qualities and features are conserved and enhanced for future generations. The Estate is an active participant of the Joint Advisory Committee for the AONB.
