Abstract
The soils around the lake are mostly of aeolian origin, well drained, with a low content of clay and a mineral fraction consisting mainly of volcanic ash. These soils are very susceptible to water and wind erosion. Only a small part of potential arable land has been cultivated, mostly for hay production and pastures for livestock. Soil erosion is still a serious problem in the Thingvallavatn area. Improved grazing policies during the last decades have, so far, not resulted in a noticeable improvement of the rangelands. An immediate, extensive land reclamation programme is needed in order to halt the erosion and restore the deteriorated vegetation. -from Authors
