Establishment and use of High Nature Value Farmland.

The conservation and maintenance of bio-diversity on agriculturally used areas has become a special concern of agrarianand environmental policy. Therefore, restoration projects with the objective of creating semi-natural grassland, have obtained increased importance throughout Europe in recent years. Procedures that are as close to nature as possible have gained special significance. Species-rich semi-natural grassland is the only existing natural source to provide the restoration and re-introduction of High Nature Value Farmland (HNVF). In recent years, a large number of different harvesting methods and application techniques have been developed for exploitation and application of seed and plant material of regional semi-natural grasslands. To ensure and to guarantee its use according to nature protection targets throughout Europe, binding European guidelines and an approved certification procedure for such material have to be developed.
