Aquatic vegetation in ditches: biodiversity in intensive production agricultural systems

Integration of biodiversity concerns into landscape planning

The preservation of biodiversity requires action not only in protected areas but also across the whole territory, in urbanized areas as well as at the country side. The implementation of the concepts of sustainable development will be one of major challenges in the years ahead.
In co-operation with partners (e.g. the nature conservation trust Stiftung Naturschutz Schleswig-Holstein) and stakeholders we develop practicable biodiversity plans at the local scale. 

Endangered opposite-leaved Pondweed (Groenlandia densa) 

Our approach combines scientific knowledge and experience in designing management plans (e.g. grazing management) with the new agri-environmental measures of the cross compliance regulation . 
We propose pragmatic solutions for ensuring the existence of an ecological infrastructure in sustainable agricultural systems.

The yellow-rattle projekt: Sucking grass roots for biodiversity
The  greater Yellow-rattle (Rhinanthus angustifolius) is named after the typical rattling sound of ripe seeds in the inflated capsules.

Like several other species of the Figwort family (Scrophulariaceae) the Greater Yellow-rattle is an annual partial parasite which hosts on grasses. It send suckers which tap water and nutrients from the roots of the host plant.

When sawn in productive grassland, the Greater Yellow-rattle is able to weaken dominant grasses and facilitate the establishment of less competitive species. 





Long before the Greater Yellow-rattle became famous as "Flower of the year 2005",  the project was launched. Seeds of local provienence were collected from an aerea bound to housing development an sawn in a species-poor grasland plot dominated by thiving Red Fescue (Festuca rubra) and Cock`s foot (Dactylus glomerata).

In the following years grasses declined substantially while in the same time herbs increased. Different mowing regimes have been tested and planting experiments carried out with weak competitors such as rosette-species.
2005 6 years after the decrease of the grasses has induced a self regulation of the parasitic population. The mosaic of patches of Yellow-rattle stands in different stages has enhanced not only the botanical diversity but also significantly the number of typical insect species of herb rich grasslands.

We would be very glad to share the lessons learned with people who are involved in similar projects. We do not have any solutions to offer, but also a lot of questions to ask!
