Minnigaff Hills and Cairnsmore of Fleet. Peaks Although the summits are not as high as many in the Scottish Highlands nor other famous mountain regions, parts of the Southern Uplands are remote and mountainous, containing about 120 Marilyns, the majority of the Donalds and a substantial number of Corbetts and Grahams.

Rivers and lochs The region is drained by numerous rivers, the most important of which are Scotland's third and fourth longest, the River Clyde at and the River Tweed at respectively. Several significant rivers drain southwards into the Solway Firth and Irish Sea including (from west to east) the River Cree, River Dee, River Urr, River Nith, River Annan and the River Esk. There are numerous lochs in the Southern Uplands, particularly in the west. The largest is Loch Ken the water lever of the loch was increased in 1936 when the Glenlochar Barrage was installed on the River Dee as well the Water of Ken was dammed to create man made lochs as part of the Galloway Hydro Scheme. Several other lochs in Galloway are dammed such as Loch Doon, Loch Bradan and Clatteringshaws Loch though many smaller ones remain in a more natural state such as Loch Dee, Loch Enoch, Loch Grannoch and Loch Trool. To the east of Moffat is the largest natural body of water in the Borders Region of the Southern Uplands, St. Mary's Loch together with the adjacent Loch of the Lowes and nearby Loch Skeen. There are several other reservoirs in the vicinity including Megget Reservoir, Talla Reservoir and Fruid Reservoir whilst Daer Reservoir lies among the Lowther Hills. Wildlife The area has a wide diversity of species and habitats. The uplands support black and red grouse, mountain hares, golden eagles, hen harriers and some unusual plant species. The western hills are home to red deer, roe deer, feral goats and wild boar. The western forests have one fifth of the Scottish population of red squirrels. Ospreys are present at some of the lochs of the Galloway Forest Park, St Mary's Loch
