Local seeds

from Wikipedia, the free encyclopedia

As area Private seed is called the seed of wild herbs , which as area intrinsically apply. In some cases, the terms "autochthonous seeds" and "regional seeds" are used synonymously. The word autochthonous (ancient Greek Αὐτόχθων) can be translated as "originated on the spot". Native plants in a certain natural area that have reproduced in multiple generations over a long period of time are defined as native to the area . Genetic differentiation and local adaptation are the result of this development process.

The use of local seeds serves to maintain and protect the biological diversity and the natural range of species in a region. Local wild plant seeds are applied, for example, when creating new biotopes , in renaturation measures , in greening measures for road construction projects and in the context of land restructuring processes , but also in natural gardens and parks as well as roof greening .

In Germany, since March 2, 2020, only local seeds may be planted in the "open nature", although cultivation in agriculture and forestry is excluded from this regulation.

Local seeds

Appropriate donor areas are harvested using suitable methods (e.g. hay thrush sowing , hay mulch sowing , hay flower sowing and ecotype sowing ) to obtain local seeds . The material obtained is then applied to the target area. The subdivision of Germany into 502 “main natural units” (according to Meynen & Schmithüsen 1953–1962) can be used as a basis for deciding whether seeds are still to be considered “local”. Local seeds should primarily be used for areas of higher value from a nature conservation point of view.

Regional seeds

For the production of regional seeds, the starting seeds of the species to be propagated are collected individually in suitable areas. It is then grown and propagated in the field over a maximum of five generations. As an area backdrop for the commercial production and sale of seeds, a division of Germany into 22 areas of origin (= occurrence areas) was determined, which was determined as part of a research project.

Representation of the 22 areas of origin for local seeds in Germany

Germany is divided into the following 22 occurrence areas:

  1. Northwest German lowlands
  2. West German lowlands with Lower Weser Uplands
  3. Northeast German lowlands
  4. East German lowlands
  5. Central German low and hill country
  6. Upper Weser and Leinebergland with resin
  7. Rhenish mountains
  8. Ore and Elbe Sandstone Mountains
  9. Upper Rhine Graben with Saarpfälzer Bergland
  10. Black Forest
  11. Southwest German mountainous region
  12. Franconian hill country
  13. Swabian Alb
  14. Franconian Alb
  15. Thuringian Forest, Fichtel Mountains and Vogtland
  16. Lower Bavarian hill and plateau region
  17. Southern foothills of the Alps
  18. Alps
  19. Bavarian and Upper Palatinate Forest
  20. Saxon loess and hill country
  21. Hessian mountain country
  22. Uckermark with Odertal

This subdivision was developed as part of a research project and was also included in the Preservation Mixture Ordinance.

Certification

There are currently two different private certification systems for local seeds, the VWW-REGIOSAATEN system of the Association of German Wild Seed and Wild Plant Producers and the REGIOZERT system of the Federal German Plant Breeders - AG Regiosaatgut.
