The protection of an endangered species alone will not increase its abundance. Conservation action is also needed The effectiveness of species protection is demonstrated by the Red List, which lets us know which species are doing poorly and which have improved. Examples of success stories According to 1988 data, the common crane was rare in Estonia. Today, however, it is in the ‘least concern’...

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 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...

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 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...

Indigenous horticultural plants. How to keep them? Horticulture has become a science, and few have retained the knowledge and skills for growing food for themselves. Fortunately, there are a number of grandmothers who have been collecting vegetable seeds year after year, and so, many of the native plants grown in the farm gardens have survived. Horticulture in Estonia dates back to the beginning...

People started to create GMOs to make production cheaper quickly and more precisely, and to improve the quality of products GMOs and their uses In a genetically modified organism (GMO), a characteristic of that organism has been altered by modern biotechnological methods. The first bacterium obtained in this way was created in 1971 in the United States. The first genetically modified (GM) plants...
