Byrums Raukar
Byrums raukar are a geological formation of a group of rauks (Swedish term for stacks) on the western shore in the north of Öland, Sweden (the island forming the Kalmar Strait with the Swedish mainland) near the village of Byrum. The group consists of about 120 limestone stacks, rich in fossils, of up to high on a stretch of beach. The area is about 3 hectares, is a Natural Monument III and a nature reserve A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological o ... since 1935.

Rauk
A rauk is a column-like landform in Sweden and Norway, often equivalent to a stack. Rauks often occur in groups called "raukfält" or "rauk fields". The limestone rauks of Gotland in the Baltic Sea are among the best known examples. Sweden Rauks are common on the island of Gotland, Sweden and on the smaller islands belonging to Gotland County. Fårö island in Gotland, is particularly rich in rauks. While Fårö is on the northern end of Gotland Holmhällars raukfält at Vamlingbo in the southern end of Gotland is also rich in rauks. Rauks in Gotland often occur in groups or fields, so-called ''raukfält''. Rauks can be found both near Gotland's many cliffs or far away from these. Other localities with rauks include Byrum on northwestern Öland neighboring Blå Jungfrun island, Hovs Hallar and Kullaberg in northwestern Scania and Härnön in northern Sweden's High Coast. Rauks on Öland are made up of limestone. A few rauks are located in the Scandinavian Mountains in nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stack (geology)
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. britannica.com They are formed when part of a headland is eroded by , which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, forming free-standing stacks and eve ...

Öland
Öland (, ; ; sometimes written ''Øland'' in other Scandinavian languages, and often ''Oland'' internationally; la, Oelandia) is the second-largest Swedish island and the smallest of the traditional provinces of Sweden. Öland has an area of and is located in the Baltic Sea just off the coast of Småland. The island has 26,000 inhabitants. It is separated from the mainland by the Kalmar Strait and connected to it by the Öland Bridge, which opened on 30 September 1972. The county seat Kalmar is on the mainland at the other end of the bridge and is an important commercial centre related to the Öland economy. The island's two municipalities are Borgholm and Mörbylånga named after their municipal seats. Much of the island is farmland, with fertile plains aided by the mild and sunny weather during summer. Öland does not have separate political representation at the national level, and is fully integrated into Sweden as part of Kalmar County. Administration Th ...

Kalmar Strait
The Kalmar Strait ( sv, Kalmarsund) is a strait in the Baltic Sea, located between the Swedish island of Öland and the province of Småland of the Swedish mainland. The strait is about long and between and in width. There is a road bridge across the strait, the Öland Bridge, opened in September 1972. Prehistory The areas along the Kalmar Strait have a heritage of Neolithic and Bronze Age habitation; moreover, Mesolithic peoples crossed the strait on an ice bridge in the early Holocene period as glaciers began to recede from Öland Öland (, ; ; sometimes written ''Øland'' in other Scandinavian languages, and often ''Oland'' internationally; la, Oelandia) is the second-largest Swedish island and the smallest of the traditional provinces of Sweden.

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossiliferous Limestone
Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces. The fossils in these rocks may be of macroscopic or microscopic size. The sort of macroscopic fossils often include crinoid stems, brachiopods, gastropods, and other hard shelled mollusk remains. In some cases, microfossils such as siliceous diatom shells in deposition may convert over time to opal and chert, providing the only inferred evidence of bioactivity preserved in limestone. Fossiliferous limestone is termed biosparite limestone under the Folk classification of sedimentary rocks. Lagerstätte are a class of fossil bearing rocks that includes fossiliferous limestone. Use Fossils in general provide geologic clues to the environment of deposition, rock formation, and the types of biological activities present at the time. Index fossils are more helpful in providing geologic r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Protected Area Management Categories
IUCN protected area categories, or IUCN protected area management categories, are categories used to classify protected areas in a system developed by the International Union for Conservation of Nature (IUCN). The enlisting of such areas is part of a strategy being used toward the conservation of the world's natural environment and biodiversity. The IUCN has developed the protected area management categories system to define, record and classify the wide variety of specific aims and concerns when categorising protected areas and their objectives. This categorisation method is recognised on a global scale by national governments and international bodies such as the United Nations and the Convention on Biological Diversity. Categories Category Ia – strict nature reserve A strict nature reserve (IUCN Category Ia) is an area which is protected from all but light human use in order to protect its biodiversity and also possibly its geological/geomorphical features. These areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date bac ...

Nature Reserves In Sweden
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...
