Abstract/Contents:Many thousands of hectares of equalizing and recultivation areas are seeded annually in Germany as a consequence of construction and development projects (highways, water supply and distribution, field rearrangement, surface mining, etc). With biodiversity preservation as a central concept of the European and national conservation legislation, and the possibility of damage to flora, it is necessary to use seed and plant material native to the region in question so as to assure that the material will be well adapted to the site conditions. This applies especially when the areas in question also fulfill an important ecological function of equalization. Demands to this effect appear ever more frequently in official guidelines and statements issued by approbation and nature conservation authorities. The public authorities as commissioners also are increasingly requiring these development efforts to use seed native to the region in question. This requirement can be met to only a limited extent in Germany by the traditional seed and plant supply. This is due to the current production and trade structures for seeds and plants - dominated through central distribution by many foreign sources and high-capacity breeding locations in the fields of agriculture and sports turf - as well as the ramifications of the currently existing seed act. Above all, as a general rule, the demands of engineering biology and erosion protection are definitely in the foreground in matters of landscape construction turf. For seeding on slopes, for example, it is therefore necessary to use alternative seeds or practicable establishment methods which engender the positive qualities of being native seeds and providing erosion control. Scientific studies have shown that native seed can be used in landscape construction and in biotope development measures in the form of regionally colleceted and propagated seed and plants, such as threshed hay seed, hay mulch seed, or seed containing grassland soils. In particular, the application of threshed hay and hay mulch as well as ecotype seed shows large advantages, simultaneously meeting the demands of engineering biology security functions and those of native seed. In light of the current discussion about German Seed Law reform, the biodiversity of domestic wild plants will be elaborated upon, and the discrepancy between seed legislation and nature protection legislation will be discussed. Reference is also made to the recently published brochure of the FLL entitled "Recommendations for special establishment procedures." In that publication, the aforementioned establishment methods are mentioned as alternatives to establishment with traditional seed; the methods' technical feasibility as well as questions about their guarantee are mentioned.
