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...

Mires have been a refuge from wars, diseases, or other people Fens and bogs have been a part of the daily life of ancient Estonians, thus becoming an integral part of culture. The mire has been a refuge from wars, diseases, or other people – a role played by the mires during World War II, when the so-called forest brothers hid there. Mires have always been a source of berries, peat, and hay...

Peat is currently mined in Estonia on approximately 184 square kilometres The area of Estonian peatlands ranks third in Europe after Finland and Sweden. In Estonia, almost 22% of the country is covered with peatlands, and in most of these areas, the thickness of the peat layers is more than 30 cm. In the Earth’s Crust Act, mineral resources (including peat) are divided into economic and...

By closing the drainage ditches of the mires, we can restore their natural water regime and the mire community will gradually recover Where peat is deposited in natural mires, this process has been significantly slowed down or even stopped in drained mires. This leads to a change in the mire functioning as a carbon sink to functioning as a carbon emitter (atmospheric emitter) and negative effects...

The difficult journey of the control of alien species: the giant hogweed and Sosnowsky’s hogweed in Estonia? Systematic control of alien species in Estonia began with two species of hogweed: the giant hogweed and Sosnowsky’s hogweed. They were brought to us mainly as silage during the Soviet era, but have proved to be troublesome nuisances that have now been controlled for more than a decade. The...

Alien species: the picture of success? Alien species invading new habitats with human help is a global problem. These alien species can seriously upset the local natural balance, reduce biodiversity, affect the economy, and endanger human health. Alien species are species that have spread beyond their natural range with the intentional or unintentional assistance of humans. However, species that...

The control of the alien species of hogweed plants and the copper tops is currently organised nationwide The most effective measures of combating alien species are the early detection of alien species, the rapid dissemination of information, and the rapid eradication of the alien species at an early stage of their spreading. However, if the species is already so widespread that eradication is no...

A person who knows better does not bring alien species to Estonia. The Ministry of the Environment must be notified immediately of any alien species released into or discovered in the wild Species know no borders, so preventing the spread of alien species must be addressed at individual, national, and international levels. At the international level, a number of conventions and agreements deal...

Most of the alien terrestrial species have been brought to Estonia on purpose Each species has its own potential entry routes, depending on the characteristics of the species and the habitat, but some modes of spreading are suitable for many species. Alien water species spread mainly in the ballast water tanks of various watercraft (ships) or on the outer surface of the hull. About 80% of the...

The economic damage caused by alien species in the European Union is estimated at 12 billion euros a year An alien species is a species that humans have intentionally (for ornamental purposes, for fur) or accidentally (with the bilge water of ships) removed from its normal range. The species would not have reached the new range on its own (due to changes of the climate or by currents). While in...
