Figure 6 - The German HNV monitoring methodology and results - HNV value decline In Germany, the HNV monitoring methodology has enabled an initial assessment of the trend in HNV value of farmland. Between 2009 and 2013, there was a significant decline of HNV value, in particular in the HNV class III, which represents the lowest value (in terms of species richness and structure).
