combination of correct soil layering, suitable restoration technique and
nutritional supply, as well as site-specific seed mixtures (adapted to the site
conditions, slow growing, lacking in biomass with slight need for nutrition),
valuable field communities that require little cultivation and are valuable for
nature conservation, can be achieved in road- and landscape construction.
part of the “Natural Grassland Seed” research project, the necessary basis for
the use of such seed mixtures and the reproduction of suitable species of seed
(natural grassland seed) is currently being drawn up. It is the aim of the
project to put basic strategies into practice to achieve the following
Necessary specialised support guidelines for the selection of species, mixture
combination, quality demands, final examination criteria and necessary
ecological construction monitoring were drawn up and adapted as a part of the
project with the aid and inclusion of existing support guidelines,
- Sufficient, permanent erosion protection in road- and landscape construction
through the combination of high-quality restoration methods with site-specific
seed mixtures of ecological types.
- A high
nature conservation value of embankment restoration (e.g. enduring,
site-specific plant stands and higher numbers of species, clearly increased
biodiversity, and also where practical the possibility to maintain rare and
endangered species in situ).
economy in the medium term (no further application of topsoil on suitable
embankments, slighter costs for subsequent improvements, reduced cultivation
expenditure for fertilising and cutting).
production of site-specific species (support-free income alternative for
regional farmers, inland added value in place of seed import).
