The weathering of the source material and the organisms that decompose organic material play an important role in soil formation Soil is the superficial loose layer of the earth’s crust, formed as a result of the weathering of the source material and the activity of plants and microorganisms. Soil is formed over a very long period of time by the interaction of many natural factors. Soil thickness...

More alien species are found in anthropogenic habitats than in natural habitats There are a wide variety of species in the anthropogenic habitats, from the first inhabitants of waste lands and landfills, many of whom are considered weeds (e.g. dandelion, plantains), to exotic plants planted in parks and arboretums. Anthropogenic terrestrial habitats can be broadly divided into two: purposefully...

The species richness of settlements is mainly concentrated to parks and gardens, where there are also more natural species Human activities affect most of today’s communities. In Estonia, humans have only refrained from significantly interfering with the development of bogs, other primitive communities are extremely rare. Even some forests that appear to be primeval forests grow on sites that were...

The North Estonian Klint has also been presented as a geological monument worthy of global attention for inclusion in the UNESCO World Heritage List The North Estonian Klint, often referred to simply as the cliffed coast, is one of Estonia’s greatest geological values and attractions. In Swedish and Danish, klint means a coastal terrace. By North Estonian Klint, we mean primarily the terraces of...

The Estonian coast, including the cliffed coast, is a flat coast in its entirety The coast is the zone between the shore region (the bottom and land of the sea or large lake, formed mainly by waves) and the bottom and mainland of the adjacent sea or large lake (Lake Võrtsjärv, Lake Peipsi). The coast is generally divided into steep coasts and flat coasts. The Estonian coast, including the cliffed...

The Estonian sea coast is diverse and the types of shores that occur here often vary after a short distance The coast is considered to be the coastal zone and the adjacent land and sea – coastal lands and coastal sea. The landward border of the coast is the imaginary line connecting the bottoms of the bays, while the seaward border is an imaginary line connecting the peaks of the peninsulas. If...

The night of ancient lights held in August is a common custom on all the beaches of the Baltic Sea The word ‘meri’ (‘sea’) has been used in Estonian for ten thousand years or more. The sea separates and the sea connects – regional differences in folk culture and lifestyle have developed along the water’s edge. Coastal people have been dependent on the changing sea, which has shaped their daily...

All the peoples of the Baltic Sea are concerned about the state of the Baltic Sea As the Baltic Sea’s ability to offset the negative pressures from human activities and other factors is rather limited, all peoples living along the Baltic Sea are concerned about the state of the ecological status of the Baltic Sea. That is why the Baltic Sea has long been one of the areas with most intensive...

The biggest problem in the Baltic Sea is anthropogenic eutrophication, or enrichment with nutrients The Baltic Sea is one of the seas most influenced by human activity in the world. The Baltic Sea basin (the area from where water flows into the sea), four times the size of the sea itself, is home to more than 85 million people. Therefore, the pollution load on the sea is quite high. Given the...

Due to the young geological age of the Baltic Sea, no endemic animal species have emerged here The Baltic Sea mixes typical freshwater and marine conditions, so there are organisms of both marine and freshwater origin. Due to these special conditions, the number of species in the Baltic Sea is lower than in a sea with typical salinity. Many of the species here live under constant stress caused by...
