Cheviot Hills in the context of "Southern Uplands"

The Pennines (/ˈpɛnaɪnz/), also known as the Pennine Chain or Pennine Hills, are an upland range mainly located in Northern England. Sometimes described as the "backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the north of the Midlands to Northumberland in North East England. From the Tyne Gap in the north, the range extends south through the North Pennines, Yorkshire Dales, South Pennines, and Peak District to end near the valley of the River Trent. The Border Moors and Cheviot Hills, which lie beyond the Tyne Gap, are included in some definitions of the range.

The range is divided into two by the Aire Gap, a wide pass formed by the valleys of the rivers Aire and Ribble. There are several spurs off the main Pennine range east into Greater Manchester and Lancashire, comprising the Rossendale Fells, West Pennine Moors, and Bowland Fells. The Howgill Fells and Orton Fells in Cumbria are also sometimes considered to be Pennine spurs. The Pennines are an important water catchment area, with numerous reservoirs in the head streams of the river valleys.

Border Moors and Forests NCA is an upland plateau region in Northern England between the North East and North West regions, and touching the Anglo-Scottish border. The region, like much of the northern English uplands, is sparsely populated, with scattered farming and hardy shepherding in river valleys. Because of this sparse population, 39% of the region is part of the Northumberland National Park in the southeast and several military assets are placed here, both modern and ancient. The NCA is of lower elevation to the Cheviot Hills to the east. The A68 is the only main road going through the region. Conifer plantations, moorland, bogs, wet heaths make up the landscape of the region, which only allows for rough grazing of sheep in most areas outside of the valleys.Afforestation is a major environmental factor within the 20th and 21st centuries, as the Kielder Forest is the largest planted forest in northern Europe and has destroyed many native mires and peat bogs of the region. As such in the 21st century preserving the moors has been a top priority in the region as its habitat is home to high biodiversity and the region also serves as an important storer of carbon in its moors.
