Järflotta is an island in Stockholm archipelago, approximately 5 km (3.1 mi) south of Nynäshamn. Once separated from the mainland by a natural sound, this navigable route was rendered unusable in more modern times by post-glacial rebound and has been replaced by the artificial Draget Canal. The island is a nature reserve. [1]

Post-glacial rebound Rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period

Post-glacial rebound is the rise of land masses after the lifting of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy, the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ocean siphoning and continental levering, the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.

Nature reserve

Järflotta is a flat island which covers about 755 ha (1,870 acres). The entire island, as well as some outlying islands, constitute a nature reserve which in total covers around 3,538 ha (8,740 acres), including water. Most of the island consists of a sandy heath and Scots pine forest. Only the central part of the island contains arable land. Unusually for Stockholm County, the island has several sandy beaches which are a habitat for a number of red listed plants. The islands surrounding Järflotta, especially Gunnarshögarna, are also included in the nature reserve and support important habitats for birds such as Caspian tern, razorbill, black guillemot and common murre. The explicit purpose of the nature reserve is to preserve an important archipelago environment and make it accessible for recreation and, for the outlying islands, to protect the bird-life. [1] Parts of the nature reserve belongs to the EU-wide Natura 2000-network. [2]

Heath shrubland habitat

A heath is a shrubland habitat found mainly on free-draining infertile, acidic soils and is characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate.

Scots pine species of plant

Scots pine is a species of pine that is native to Eurasia, ranging from Western Europe to Eastern Siberia, south to the Caucasus Mountains and Anatolia, and north to well inside the Arctic Circle in Scandinavia. In the north of its range, it occurs from sea level to 1,000 m (3,300 ft), while in the south of its range it is a high altitude mountain tree, growing at 1,200–2,600 m (3,900–8,500 ft) altitude. It is readily identified by its combination of fairly short, blue-green leaves and orange-red bark.

Arable land Land capable of being ploughed and used to grow crops

Arable land is, according to one definition, land capable of being ploughed and used to grow crops. In Britain, it was traditionally contrasted with pasturable land such as heaths which could be used for sheep-rearing but not farmland.

Coastal artillery battery

Parts of a former coastal artillery battery, which now consists of a single 9.4in (24cm 43calibre) Bofors M06 naval gun, are still present on Järflotta. The site was decommissioned during the 1990s, and today is preserved as a protected historical building. [3] [4] The 9.4in gun is believed to be the largest caliber preserved in Sweden.

Bofors company

Bofors AB is a Swedish arms manufacturer. The name has been associated with the iron industry and artillery manufacturing for more than 350 years.

The coastal artillery battery, which dates from 1942, is part of a series of fortifications built during World War II to protect Södertälje and Nynäshamn from attack and minefields in the Baltic Sea. The battery originally consisted of three guns that were relocated to Järflotta from a fortification in Vaxholm. Barbed wire and a total of 291 concrete bunkers defended the site from direct assault. When the battery was deemed fit for action in 1943 it was manned by 605 personnel. After the war, the battery remained part of Swedish defensive planning during the Cold War. As late as 1954, it was used in exercises simulating seaborne attacks by the Soviet Navy. In 1948, nine people died in an explosion at the gun battery while handling ammunition. Whether the cause was the result of sabotage or mishandling of the ammunition has never been clarified. [4] Although the coastal battery ceased as an artillery platform in the 1950s, it remained in military use until it was decommissioned in the 1990s. [3]

World War II 1939–1945 global war

World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

Naval mine explosive weapon for use in seas and waterways, triggered by the targets approach

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. 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.

Fort Monroe fortress

Fort Monroe is a decommissioned military installation in Hampton, Virginia at Old Point Comfort, the southern tip of the Virginia Peninsula, United States. Along with Fort Wool, Fort Monroe originally guarded the navigation channel between the Chesapeake Bay and Hampton Roads—the natural roadstead at the confluence of the Elizabeth, the Nansemond and the James rivers. Until disarmament in 1946, the areas protected by the fort were the entire Chesapeake Bay and Potomac River regions, including the water approaches to the cities of Washington, D.C. and Baltimore, Maryland, along with important shipyards and naval bases in the Hampton Roads area. Surrounded by a moat, the six-sided bastion fort is the largest fort by area ever built in the United States.

Krepost Sveaborg

The Krepost Sveaborg was an Imperial Russian system of land and coastal fortifications constructed around Helsinki during the First World War. The purpose of the fortress was to provide a secure naval base for the Russian Baltic fleet and to protect Helsinki and block routes to Saint Petersburg from a possible German invasion. Krepost Sveaborg was part of Peter the Great's Naval Fortress, a coastal fortification system protecting access to Saint Petersburg by sea. The central part of Krepost Sveaborg was the old fortress of Suomenlinna where the fortress headquarters were located. Due to technological advances in artillery the old fortress was no longer capable of providing a sufficient protection, and a new main defensive line was built well beyond the old fortress boundaries. New coastal artillery guns built on outlying islands protected Krepost Sveaborg from the sea, while fortified lines constructed around Helsinki were intended to stop any attacks on land. The primary coastal guns were 10 in (254 mm) model 1891 guns and 6 in (152 mm) model 1892 Canet guns. Older 11 in (279 mm) model 1877 guns were also used. In summer 1917 the fortress had two hundred coastal or anti-landing guns, of which 24 were 10-inch guns in six batteries, 16 were 6-inch Canet guns in four batteries and twelve were 11-inch guns in three batteries. The artillery used in land fortifications included older coastal guns, old fixed carriage guns and newer light field guns. In March 1917, Krepost Sveaborg had a total of 463 guns, although many of them were obsolescent. Krepost Sveaborg was still partly incomplete in 1917 when the February Revolution halted most of the construction work. Some further construction work was carried out during the remaining year, but all work halted during the October Revolution. Following the Finnish Declaration of Independence, parts of the land fortifications were used in the Finnish Civil War. The coastal fortifications were later taken over by Finland to protect Helsinki, while the land fortifications were mostly abandoned and disarmed.

Battery Steele United States military fortification

Battery Steele is a United States military fortification on Peaks Island, Portland, Maine in Casco Bay. Completed in 1942 as part of World War II, it is located on 14 acres (5.7 ha) on the oceanside area of the island, formerly part of the Peaks Island Military Reservation. It is named for Harry Lee Steele, who was a Coast Artillery officer during World War I. It was armed with two 16-inch MkIIMI guns and, with a 12-inch gun battery at Fort Levett on Cushing Island, replaced all previous heavy guns in the Harbor Defenses of Portland. It was built to protect Casco Bay, particularly Portland harbor, from Kennebunk to Popham Beach in Phippsburg. According to Kim MacIsaac and historian Joel Eastman in An Island at War, “Battery Steele is not only the largest gun battery built on Peaks Island, but also an example of the largest battery ever built anywhere in the United States.” In 1995, after decades of non-use, the Peaks Island Land Preserve, a community land preservation group, formed to purchase the area and forever preserve it as a public space. On October 20, 2005, the property was listed on the National Register of Historic Places. Other coast defense structures on the island include fire control towers and the counterweight for a disappearing searchlight tower.
