EU Member States must work to ensure that all bodies of surface water are at least in good condition The pollution of surface water bodies with hazardous substances in Estonia occurs primarily in connection with pollution from oil shale production in Ida-Viru County since the 1930s. However, a more significant pollution load from agriculture (manure, fertilisers, pesticide residues) arose during...

Inland waters form very diverse habitats Inland water bodies vary in size, depth, amount and nature of solutes, water flow rate, the characteristics of the bottom, water temperature, and many other aspects. Their combinations form very different habitats inhabited by very different species. The number of species usually increases with the increase in the area or catchment basin of a water body, as...

The Estonian water network is dense, because the amount of precipitation exceeds evaporation here Watercourses There are thousands of watercourses in Estonia – according to the literature, more than 7,300 – with a total length of more than 31,000 km [1]. There are almost 3000 watercourses registered in the Estonian Nature Information System [2]. Most Estonian watercourses are short (94.3%), up to...

According to the water flow, inland water bodies are divided into watercourses and stagnant water bodies Inland waters include waters separated from the oceans: rivers, lakes, artificial water bodies, groundwater, continental ice, and glacier water [1]. People usually associate inland waters with activities such as fishing, hiking, quenching their thirst, and watering plants. However, the water...

The main reason for the loss of heritage communities was the abandonment of handicraft, and intensive agriculture Heritage meadows or semi-natural communities are also called heritage communities. Both names refer to a close connection with man and to the fact that we have inherited these communities from our ancestors. Semi-natural communities have emerged with the help of humans, as a result of...

Preserving heritage communities is one of the most important responsibilities of our nature conservation As heritage meadows have been created with the help of man, they also have great cultural-historical and aesthetic value. When humans no longer care for these communities, they will overgrow. Junipers, reeds, trees, or shrubs will take over the grasslands and all the great biodiversity is lost...

Most of the species on the Estonian Red List are associated with semi-natural communities Heritage meadows have an exceptionally high species diversity. They are an important habitat for nearly 700 plant species. 76 plant species have been found growing on 1 m 2 of the Laelatu wooded meadow [1] – it is one of the densest plant communities in the world in terms of species richness. Alvars with dry...

Heritage meadows have been created as a result of nature-friendly management Coastal meadow is a grassland on the sea shore that is more or less affected by saline seawater. Coastal meadows are located in flat, turfed coastal areas. As animals have historically been grazed there, they are therefore also called coastal pastures or coastal grasslands. Coastal meadows are mainly located in Western...

The natural values of meadows, or heritage communities, can only be preserved by human intervention Heritage meadows, also called semi-natural communities or heritage communities, are grasslands that have traditionally been used as pastures or hayfields. The biota of the heritage meadows is natural – the heritage meadows have not been ploughed, fertilised, and no seeds of cultivated plants have...

Preservation of forest biodiversity, i.e. the ability to function and provide benefits even in the face of unexpected changes, requires historical continuity and ensuring spatial coherence Approximately 20,000 species of plants, animals, and fungi live in Estonian forests [1]. Our most abundant species group is insects (estimated at about 10,000), and we have 2,000 to 2,500 species of fungi and up...
