摘要

Unused grassland areas, the majority of which are situated in the south-eastern and west-em parts of Lithuania, were formed during the land reform as a result of the changes in the ratio between perennial vegetation and arable land. Various factors were responsible for the appearance of unused grasslands: land reform peculiarities, inappropriate exploitation of land amelioration equipment, soil erosion and acidification, and inadequate use of grassland areas. A large part of the unused grasslands iscomposed of cultivated meadows and pastures that have not been fertilised and renovated for the last decade. Parts of such areas are fallows, and the other parts are being conserved. The areas of cultivated meadows and pastures are being conserved first,then former cereal fields, and last row crop fields. The main criterion for grassland conservation is the soil texture. Of the total amount of unused meadows and grasslands 54% is left for spontaneous overgrowth with various plants, trees, and shrubs, while 64% is afforested. Meadows and pastures most commonly overgrow spontaneously with white alder and birch, swamps and peatlands with birch, and quarries and sands with white alder, pine, and birch. Fir is commonly used for the afforestation of meadows, pastures, swamps, and peatlands, while pine is most commonly used for quarries and sands.
