Pressures
Relative magnitude: medium
| Abandonment of meadows | Populations of many species (mainly plant and bird) inhabiting natural meadows and seminatural grasslands decreased due to changes in land use. Such threats exist because of overgrowing of grasslands due to cessation of traditional management: cattle grazing and mowing. In some areas also an adoption of intensive methods of farming (ploughing) has reduced biodiversity. The most remarkable reduction of species diversity has been observed in the meadow bird community, which includes threatened species: Ruff (Philomachus pugnax), Baltic Dunlin (Calidris alpina schinzii), Black-tailed Godwit (Limosa limosa). |
| Increase of edge use in private lands | Loss of ecological corridors which are important for species migration. |
| Possible intensification in future | In spite of the remarkable decrease of agricultural activities during the past years, an intensification in the near future is expected. |
