Clwydian Range and Dee Valley in the context of "Ericaceae"

North Wales (Welsh: Gogledd Cymru [ˈɡɔɡlɛð ˈkəmrɨ]) is a region of Wales, encompassing its northernmost areas. It borders mid Wales to the south, England to the east, and the Irish Sea to the north and west. The area is highly mountainous and rural, with Snowdonia National Park (Parc Cenedlaethol Eryri) and the Clwydian Range and Dee Valley (Bryniau Clwyd a Dyffryn Dyfrdwy), known for its mountains, waterfalls and trails, wholly within the region. Its population is concentrated in the north-east and northern coastal areas, with significant Welsh-speaking populations in its western and rural areas. North Wales is imprecisely defined, lacking any exact definition or administrative structure. It is commonly defined administratively as its six most northern principal areas, but other definitions exist, with Montgomeryshire historically considered to be part of the region.

Those from North Wales are sometimes referred to as "Gogs" (from Welsh gogledd 'north'); in turn, those from South Wales are sometimes called "Hwntws" by those from North Wales.

North East Wales (Welsh: Gogledd-Ddwyrain Cymru) is an area or region of Wales, commonly defined as a grouping of the principal areas of Denbighshire, Flintshire, and Wrexham County Borough in the north-east of the country. These principal areas comprise most (excluding Colwyn, and parts of Glyndŵr) of the former administrative county of Clwyd. It is bordered by Conwy, and Gwynedd, in North West Wales to the west, Powys, in Mid Wales to the south, the English counties of Cheshire, and Shropshire to the east, and the Irish Sea, and Dee estuary to the north. It is the more urban, densely populated, and industrial part of the north Wales geographic region, centred on the city of Wrexham and the towns of Rhyl and Prestatyn, and the conurbation of Deeside. The region's close links with North West England in general and Merseyside in particular (together as the "Mersey-Dee" economic sub-region) are crucial to the region's economy.

The Clwydian Range and Dee Valley Area of Outstanding Natural Beauty is located in the region. Other attractions include historical buildings such as Chirk Castle, and Erddig in Wrexham, valley towns such as Corwen and Llangollen, and the Pontcysyllte Aqueduct and Canal World Heritage Site.

Flintshire (Welsh: Sir y Fflint) is a county in the north-east of Wales. It borders the Irish Sea to the north, the Dee Estuary to the north-east, the English county of Cheshire to the east, Wrexham County Borough to the south, and Denbighshire to the west. Connah's Quay is the largest town, and Flintshire County Council is based in Ewloe.

The county covers 169 square miles (440 km), with a population of 155,000 in 2021. After Connah's Quay (16,771), the largest settlements are Flint (13,736), Buckley (16,127) and Mold (10,123). The east of the county is industrialised and contains the Deeside conurbation, which extends into Cheshire and has a population of 53,568. The adjacent coast is also home to industry, but further west has been developed for tourism, particularly at Talacre. Inland, the west of the county is sparsely populated and characterised by gentle hills, including part of the Clwydian Range and Dee Valley AONB. The county is part of the preserved county of Clwyd.
