Lowland semi-natural grassland is grassland that has not had significant fertilizer or herbicide applied to it, and exists at an altitude of less than 350 metres.
[1] Such grasslands are sometimes managed as grazing or as winter food for livestock -cutting for hay or silage.
Because of their traditional management, they contain a high diversity of species native to the particular country.
[3] They have formed as a result of human activity.
Man has been managing land since mesolithic times.
