Alvars can be best described as thin-soiled meadows rich in lime where there are almost no trees or bushes. Alvars can have up to 20 centimetres of soil but at times there is no soil at all and vegetation in these cases can be found only in cracks of the cliffs or smaller concavities. In different seasons the same alvar can look very different, depending on the amount of precipitation. On Sarve peninsula you can see alvars in gravel-pebble beach ridge by the sea. These alvars are different in comparison with those in North-Estonia or other alvars in West-Estonia.
