A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.
Loch Leven is a fresh water loch located immediately to the east of the burgh of Kinross in Perth and Kinross council area, central Scotland. Roughly triangular, the loch is about 6 km (3.7 mi) at its longest. Prior to the canalisation of the River Leven, and the partial draining of the loch in 1826–36, Loch Leven was considerably larger. The drop in water level by 1.4 m reduced the loch to 75% of its former size, and exposed several small islands, as well as greatly increasing the size of the existing ones.
RSPB Minsmere is a nature reserve owned and managed by the Royal Society for the Protection of Birds (RSPB) at Minsmere, Suffolk. The 1,000-hectare (2,500-acre) site has been managed by the RSPB since 1947 and covers areas of reed bed, lowland heath, acid grassland, wet grassland, woodland and shingle vegetation. It lies within the Suffolk Coast and Heaths Area of Outstanding Natural Beauty and the Suffolk Heritage Coast area. It is conserved as a Site of Special Scientific Interest, Special Area of Conservation, Special Protection Area and Ramsar site.
The Lochs of Spiggie and Brow are located west of Boddam in the parish of Dunrossness, in the South Mainland of Shetland, Scotland, about 6 km north of Sumburgh.
Insh Marshes are an area of floodplain of the River Spey between Kingussie and Kincraig in Badenoch and Strathspey, Highland, Scotland. The marshes are said to be one of the most important wetlands in Europe. They lie at altitude of approximately 240 to 220 m above sea level, and form one of the largest areas of floodplain mire and fen vegetation in Scotland.
RSPB Dearne Valley Old Moor is an 89-hectare (220-acre) wetlands nature reserve in the Dearne Valley near Barnsley, South Yorkshire, run by the Royal Society for the Protection of Birds (RSPB). It lies on the junction of the A633 and A6195 roads and is bordered by the Trans Pennine Trail long-distance path. Following the end of coal mining locally, the Dearne Valley had become a derelict post-industrial area, and the removal of soil to cover an adjacent polluted site enabled the creation of the wetlands at Old Moor.
Crimond is a village in Aberdeenshire, in the northeast of Scotland, located 9 miles (14 km) northwest of the port of Peterhead and just over 2 miles (3.2 km) from the coast.
Abernethy Forest is a remnant of the Caledonian Forest in Strathspey, in the Highland council area of Scotland. It lies within the Cairngorms National Park, close to the villages of Nethy Bridge, Boat of Garten, and Aviemore. The forest is an RSPB reserve, close to Loch Garten Osprey Centre, which is also owned by the RSPB. It is popular with walkers, as there are various trails throughout the reserve. The forest forms part of the wider Abernethy National Nature Reserve.
The osprey is a medium large raptor which is a specialist fish-eater with a worldwide distribution. The subspecies Pandion haliaetus haliaetus is native to Eurasia and is found in the British Isles, where it is a scarce breeder primarily in Scotland with smaller numbers in England and Wales. It became extinct in the British Isles in 1916, but recolonised in 1954. Scandinavian birds migrate through Britain on the way to their breeding sites.
The fauna of Scotland is generally typical of the northwest European part of the Palearctic realm, although several of the country's larger mammals were hunted to extinction in historic times and human activity has also led to various species of wildlife being introduced. Scotland's diverse temperate environments support 62 species of wild mammals, including a population of wild cats, important numbers of grey and harbour seals and the most northerly colony of bottlenose dolphins in the world.
Rattray, (found at grid reference NK088578) had been settled as far back as 4000 BC and was named a Royal Burgh in 1564 by Mary, Queen of Scots, "to put an end to the disputes about superiority over it between William Keith, 4th Earl Marischal and George Hay, 7th Earl of Erroll". The ancient burgh was located near to Crimond, but the village was largely destroyed and never recovered after a storm in the 18th century that covered it in shifting sands from the nearby dunes at Rattray Head. However, there is still a small modern settlement in the area.
The Castle of Rattray was a medieval Scottish castle, with multiple variations on its structure over approximately six centuries. Originally built as a "late 12th- or early 13th century defensive motte" it provided protection for Starny Keppie Harbour and Rattray village. Sometime between 1214 and 1233 it was upgraded by William Comyn, jure uxoris Earl of Buchan before being destroyed in the 1308 Harrying of Buchan. After Comyn's timber castle was burned down, it was replaced by a stronger stone castle which was engulfed during a 1720 sand storm along with nearby Rattray village. After the storm, the castle was not dug out and remains covered to this day. The castle was described by W. Douglas Simpson as one of the nine castles of the Knuckle, referring to the rocky headland of north-east Aberdeenshire.
Roshven is a township located on the eastern shoreline of Loch Ailort, in Lochaber, in the council area of Highland, Scotland. Towering above it is Rois-bheinn, the highest hill in the area.
Ham Wall is an English wetland National Nature Reserve (NNR) 4 kilometres (2.5 mi) west of Glastonbury on the Somerset Levels. It is managed by the Royal Society for the Protection of Birds (RSPB). Since the last Ice Age, decomposing plants in the marshes of the Brue valley in Somerset have accumulated as deep layers of peat that were commercially exploited on a large scale in the twentieth century. Consumer demand eventually declined, and in 1994 the landowners, Fisons, gave their old workings to what is now Natural England, who passed the management of the 260 hectares Ham Wall section to the RSPB.
Knockewart Loch or Loch Jargon was situated in a hollow lying area beneath Knockewart Hill in the Parish of Ardrossan, North Ayrshire, Scotland. The old loch has become largely drained and overgrown since the late 19th century.
The North Norfolk Coast Site of Special Scientific Interest (SSSI) is an area of European importance for wildlife in Norfolk, England. It comprises 7,700 ha (19,027 acres) of the county's north coast from just west of Holme-next-the-Sea to Kelling, and is additionally protected through Natura 2000, Special Protection Area (SPA) listings; it is also part of the Norfolk Coast Area of Outstanding Natural Beauty (AONB). The North Norfolk Coast is also designated as a wetland of international importance on the Ramsar list and most of it is a Biosphere Reserve.

Loch Lomond National Nature Reserve (NNR) encompasses 430 hectares of land at the southeastern part of Loch Lomond in the council areas of Stirling and West Dunbartonshire, in Scotland. It covers the islands of Inchcailloch, Clairinsh, Torrinch, Creinch and Aber Isle, alongside areas of woodland and wetlands to either side of the mouth of the Endrick Water. NatureScot owns two parts of the reserve - the island of Inchcailloch and part of Gartfairn Wood - and the rest is privately owned. The reserve is managed by a partnership consisting of NatureScot, the RSPB Scotland and the Loch Lomond and The Trossachs National Park, along with the owners and tenants of the land under agreements. Within this framework NatureScot directly manage the islands of Clairinsh, Inchcailloch, Torrinch and Creinch, and land to the north of the Endrick Water. The RSPB manages the area to the south of the Endrick Water, and the national park manages visitor facilities on Inchcailloch.
Loch of Kinnordy is a small loch located just west of town of Kirriemuir in Angus, Scotland, which is an important wildlife habitat. The loch itself is approximately 22 hectares, though this has varied over time with drainage attempts and the silting up of the outflow stream. Including surrounding fen, swamp and mire, 85 hectares are protected as a Ramsar Site.
