RegioDiv

Background

Since 2.3.2020 the use of autochtonous material is mandatory for the putting plant materials in the free landscape according to §40 BNatSchG in Germany. BfN 2020 . Thus the existing market of regional seed, "Regiosaatgut", has a particular responsibility.

The production of regional seed is based on a system of 22 seed transfer zones (regions of origin), which were developed by DBU project (Prasse et al. 2010) . This system is based on the system of ecoregions after Meynen & Schmithüsen (1953-1962) and further grouping criteria. Although general population genetic aspects were included (in particular isolation-by-distance) no empirical data on spatial genetic structure of plant species were considered, because such data were not available. To close this knowledge gap, BfN has funded the project RegioDiv from 2020-2023.

Aims

1. Build up an empirical data base of patterns of genetic variation and differentiation in >25 representative species used in grassland restoration (i.e. grasses, herbs legumes).
2. Collection of leaf material in all 22 seed transfer zones from min 3 sites.
3. Genetic analysis with genome-representative SNP markers (single nucleotide polymorphism) and analysis of  population genetic structure.
4. Deduce recommendation for practical management of seed material in the context of §40 BNatSchG.
