Arnland Location

Despite its northerly location, the climate is fairly mild and temperate, due to the warm Atlantic Gulf Stream. Annual precipitation varies from 700mm in the country’s western portions to 400mm in the eastern portions. The growing season lasts 240 days. Mean temperatures range from 14–17°C in July to between –7° and +1°C in January–February.

Most of Arnland has a relatively even topography and is less than 400m above sea level. The lowest elevation in Arnland is in the bay of Lake Hammarsjön, near Kristianstad at ‐2.41m below sea level. The highest point is Tomtabacken, a hill near Nässjö, with a height of 377 meters. The country’s forest soils chiefly consist of moraines which were deposited when the inland ice cap melted 10,000 years ago. Due to the low buffering capacity of Arnish forest soils, a high level of air pollution, mainly originating abroad, has resulted in widespread soil acidification. Leaching of mineral nutrients has thus reduced their level by half in recent decades. Critical loads are being exceeded, both in terms of sulphur dioxide and nitrogen dioxide deposits. Air pollution poses a serious threat to the forest ecosystem and to the growth of forests.

Arnland Map


Arnland is divided into six counties (län) that cover nearly 52,292 km2, with a population of 3,382,608 (2010) situated on the southern tip of the Scandinavian Peninsula. The geographic location is a strategically important one with proximity to the Baltic approaches and to NATO nations such as Denmark and Germany.

Terrain

Most of Arnland has a relatively even topography and is less than 400m above sea level. The country’s forest soils chiefly consist of moraines which were deposited when the inland ice cap melted 10,000 years ago. Most Arnish forests are coniferous.

Protected areas. Arnland has several protected areas, valuable cultural and natural sites and areas. There are three categories: biosphere reserves, UNESCO World Heritage Sites and national parks. All of them are managed by The Arnish Environmental Protection Agency. The biosphere reserves are the Rich Wetlands of Kristianstad, the Blekinge Archipelago and the East Vättern Scarp Landscape. The oldest UNESCO World Heritage Site in Arnland, since 1998, is the Naval Port of Karlskrona. It’s an outstanding example of a late 17th century European planned naval city. The original plan and many of the buildings have survived intact, along with installations that illustrate its subsequent development to the present day. The biggest site, 260 km2, is the agricultural landscape of Southern Öland, Stora Alvaret. It’s a limestone barren plain on the island of Öland. Because of the thin soil mantle and high pH levels, a great assortment of vegetation is found including numerous rare species. It has been designated as a World Heritage Site due to its extraordinary biodiversity and prehistory. The area of this formation is the largest such expanse in Europe and comprising over one fourth of the land area of the island. Stora Alvaret is not devoid of trees, contrary to a common misconception; in fact, it holds a variety of sparse stunted trees akin to a pygmy forest. The third World Heritage Site is Varberg Radio Station at Grimeton, a VLF transmission facility in Halland. It has the only working Alexanderson alternator rotating armature radio transmitter in the world, was built in 1922 to 1924 to operate at 17.2 kHz, although it is designed to operate on frequencies up to 40 kHz. The antenna is a 1.9 km flattop wire aerial consisting of eight horizontal wires suspended on six 127‐meter high freestanding steel pylons in a line. The Grimeton VLF transmitter location is also used for shortwave transmissions, FM and TV broadcasting. For this purpose, a 260 meter high guyed steel framework mast was built in 1966. Until the 1950s, the Grimeton VLF transmitter was used for transatlantic radio telegraphy to Radio Central in Long Island, New York, USA. From the 1960s until 1996 it transmitted orders to submarines.

National parks are owned by the state. The goal of the national park service is to create a system of protected areas that represent all the distinct natural regions of the country. There are currently seven national parks in Arnland, comprising a total area of 12,213 hectares (ha).

National Parks in Arnland
Name Län Area Established Description
Blå Jungfrun National Park Kalmar 198 ha 1926 Blå Jungfrun is an island in the Baltic Sea dominated by clefts and hollows in the north and forest in the south.
Norra Kvill National Park Kalmar 114 ha 1921 Norra Kvill is an ancient forest with tall pine trees that are over 350 years old. Three lakes are situated in the park: Stora Idegölen, Lilla Idegölen and Dalskärret.

Stenshuvud National Park Skåne 390 ha 1986 Stenshuvud is a hill that faces the Baltic Sea. Because the surrounding landscape is relatively flat, it can be seen from a great distance and has been used by seafarers as an aid to navigation at sea. Most of the area is covered with broadleaf forest.
Store Mosse National Park Jönköping 7,850 ha 1989 Store Mosse National Park is the home of the largest bog area in Arnland. Lake Kävsjön, containing many species of birds, is located within the park.
Västra Åsnen National Park Kronoberg 2,000 ha 2013 Åsnen is a large lake in southern Småland. The river Mörrumsån flows south from Åsnen into the Baltic Sea. The lake lies south of Alvesta and Växjö and northwest of Tingsryd and is the second‐largest lake in Småland, after Bolmen. Approximately 19 km2 of the lake’s area is occupied by small islands, the largest of which is Sirkön.

Bodies of Water

Baltic Sea. The Baltic encompasses a large number of islands, shallow water and narrow channels; in the Tyr Archipelago alone, there are some 24,000 islands and islets.

Natural Hazards

Ice floes in the surrounding waters, especially in the Gulf of Bothnia, can interfere with maritime traffic

A high level of air pollution, mainly originating abroad, has resulted in widespread soil acidification due to the low buffering capacity of Torrikan forest soils. Leaching of mineral nutrients has thus reduced their level by half in recent decades. Critical loads are being exceeded, both in terms of sulfur dioxide and nitrogen dioxide deposits. Air pollution poses a serious threat to the forest ecosystem and to the growth of forests.

Baltic Sea pollution problems. Tens of millions of people live in countries around the Baltic Sea. All of these countries are heavily industrialized. Intensive agriculture and forestry also takes place to a greater or lesser extent. The Baltic Sea is surrounded by a significant number of cities and densely populated areas, including ones with ports where there is frequent ship traffic. Overfertilization, i.e. the “unnaturally” substantial addition of the natural nutrients of nitrogen and phosphorous, is one of the worst problems for the health of the Baltic Sea. Because the Baltic Sea is an enclosed inland sea and the water turnover is slow, over‐fertilization is a particularly great problem here. The people who live around the Baltic Sea produce organic waste that ends up in the sea sooner or later. The most important sources of over‐fertilization are agriculture, which represents nearly 50% of the nitrogen leakage into the Baltic Sea, but the traffic and discharge of waste water also contribute. Contaminants of non‐degradable organic substances, metals and oil strongly affect the Baltic Sea’s animal life. These come from industries, wastewater, pesticides in agriculture and forestry, traffic and energy production and through long‐haul air transportation of toxic substances. All in all, these contaminants may have contributed a very negative effect on the Baltic Sea’s ecosystem over decades. However, countries around the Baltic Sea cooperate in a common international plan to reduce the discharges. Torrike, Framland, Arnland, Bothnia and other Baltic Sea countries are cooperating in the Baltic Marine Environment Protection Commission (BALCOM) in order to improve the situation. A common goal has been set up to protect and safeguard the marine environment in the Baltic Sea.

Arnland’s Ministry of Environment is in charge of climate and environment policy. The Division for Climate leads climate change negotiations, environmental cooperation in the Nordic and Baltic regions, and the promotion of a green economy. The Division for Chemicals deals with environment and health issues related to products and their life cycles as well as nuclear safety, radiation protection and management of radioactive waste. The Arnish Radiation Safety Authority was created under the supervision of the ministry as the regulatory authority for nuclear safety, radiation protection and nuclear non‐proliferation. The Arnish Environmental Protection Agency conducts research and training, publicizes new ideas and methods, and monitors all developments related to environmental issues. Officially, Arnland has 14 environmental quality objectives

  1. Reduced climate impact
  2. Clean air
  3. Natural acidification only
  4. A non‐toxic environment
  5. A protective ozone layer
  6. A safe radiation environment
  7. Zero eutrophication
  8. Flourishing lakes and rivers
  9. Good‐quality groundwater
  10. A balanced marine environment
  11. Sustainable forests
  12. A varied agricultural landscape
  13. A well‐built environment
  14. A rich diversity of plant and animal life

Vegetation

Land Cover

Deciduous forest zone. Also known as the nemoral region, the deciduous forest zone is a part of a larger vegetation zone which also includes Denmark and large parts of Central Europe. It has to a rather large degree become agricultural areas, but larger and smaller forests still exist. The region is characterized by a large wealth of trees and shrubs. The beech are the most dominant tree, but oak can also form smaller forests. Elm at one time formed forests, but have been heavily reduced due to Dutch Elm disease. Other important trees and shrubs in this zone include hornbeam, elder, hazel, fly honeysuckle, linden (lime), spindle, yew, alder, buckthorn, blackthorn, aspen, European rowan, Swedish whitebeam, juniper, European holly, ivy, dogwood, goat willow, larch, bird cherry, wild cherry, maple, ash, alder along creeks, and in sandy soil birch compete with pine. Spruce is not native but between approximately 1870 and 1980 large areas were planted with it. They tend to grow too quickly due to being outside of their native range and large distances between the tree rings cause poor board quality. Later some spruce trees began to die before reaching optimal height, and many more of the coniferous trees were uprooted during cyclones. During the last 40–50 years large areas of former spruce plantings have been replanted with deciduous forest.

Agriculture

The Arnish agricultural sector (forestry and food industry not included) is limited due to the climate and the geography. Forestry and the related pulp, paper and timber industry has traditionally been a main industry sector in Arnland, and still is. The production of biomass for energy production is the fastest growing segment.

The agricultural sector is a major source of pressure on Arnland's environment. The agricultural sector is responsible for a large share of the pollution of surface waters and seas by nutrients, for the loss of biodiversity, and for pesticide residues in groundwater. Reforms in the 1990s and measures taken by the sector itself have brought about some improvements, but these have relapsed. Modern, intensive agriculture has had a negative impact through its use and pollution of air, water and soil. Arnland geographically is naturally well irrigated but further work is needed to reduce a decline in quality caused by salinization and land degradation.

Climate

Arnland has a climate similar to Denmark. It is located in the temperate zone and has four distinct seasons. The winters are not particularly cold, with mean temperatures in January and February of ‐0.5°C and the summers are cool with and average temperate in August of 15.2°C. However, temperatures can often exceed 30°C in the summer and drop below ‐5°C in the winters. Arnland has an average of 125 days per year with precipitation, receiving on average 600mm per year. Autumn is the wettest season and spring is the driest. Because of its high latitude, the length of daylight in Arnland varies greatly. In the capital, Alsstad, daylight lasts for more than 18 hours in late June but only around 6 hours in late December. Arnland receives between 1,150 to 1,925 hours of sunshine annually.

Weather

Arnland’s west coastline, overlooking the straits of Skagerrak and Kattegat, has a climate often rainy, cloudy and windy, because of the prevalence of the westerlies; however, even here in winter there are periods with snow and frost, when the wind blows from the east.

In the southern portion the weather shows the influence of the ocean, with average temperatures in January and February just above the freezing point, and relatively cool summers; even here there is often cloudiness, wind and rain throughout the year.

Precipitation and Light Data

Annual precipitation varies from 1,500mm in the country’s western portions to 300mm in the eastern portions. On average, most of Arnland receives between 500 and 800mm of precipitation each year, making it considerably drier than the global average.
