Arable weeds

Arable weed monitoring

Arable weed monitoring focuses on the vegetation of arable land. Arable land forms the largest part of agricultural land, but has a low floristic diversity, especially under intensive management.

A change in the management of large area crops, e.g. winter wheat, can have a major impact on floristic diversity and thus on the overall biodiversity of the agricultural landscape. The promotion of low-input crops, e.g. legumes, can create special conditions for specific organisms.

Various programmes currently promote measures to increase biodiversity in the agricultural landscape. Most of them do not primarily promote weed diversity, but aim to promote insects or mammals, for example.
Within the module "Arable Weed Monitoring", different monitoring methods for determining weed diversity are applied and compared. Within the citizen science-based approach, for example, interested farmers record their field weeds. By using an app-based identification tool for plants (e.g. Flora Incognita or Pl@ntNet), it should be made easy for farmers to determine the weediness of their land and make their data available for a national monitoring programme of floristic diversity. Ultimately, the methodology that fits best the framework conditions and objectives of a nationwide monitoring programme should be identified.
