Suggestions for improvement:
a. High nature value farmland area
- The most promising approach for the future development of this indicator lies in a systematic addition of national (biodiversity) data.
- For a more frequent update of the 'High nature value farmland area' indicator, a stratified network of representative sample areas could be set up, to monitor changes in the surface of high nature value farmland every 2–3 years. This would involve some costs since these updates could not rely on automated procedures and existing data. Such an approach could utilize modern, more sophisticated satellite observation techniques, as well as standard field survey techniques. Recently a 'Sampling framework and strategy for monitoring of European habitats' has been developed by the BIOHAB and BIOPRESS research communities (www.biohab.alterra.nl; http://www.creaf.uab.es/biopress), estimating the total cost of different approaches (Jongman, R. H. G. ; Bunce, R. G. H.; Metzger, M. J.; Mücher, C. A.; Howard, D. C. and Mateus, V. L. . 2006. Objectives and Applications of a Statistical Environmenta Stratification of Europe. Landscape Ecology Volume 21, Number 3/April, 2006.).
- The methods mentioned earlier are not fully satisfactory and in many countries work to estimate the HNV area using national data, information and methods is underway.
c. Area under biodiversity supportive agri‑environment schemes
Biodiversity relevant measures have to be defined in a transparent manner (possibly considered at a certain percentage if only partly relevant).
