New findings in the field of biodiversity monitoring are regularly published and technical innovations are also coming onto the market. It is therefore necessary to regularly adapt and update the Biodiversity Monitoring Database. An important step is to integrate "Level 2" monitoring into the database. This monitoring should take place every 3 – 5 years on representative farms and by monitoring of populations of key species. The aim is to monitor the real impact of the biodiversity measures on habitats and species on and in the surroundings of the farms. Here too, development is progressing and we hope to have a practicable, cost-effective and meaningful approach established in 2021.
