Implementation of the High Nature Value
Farmland Indicator
Approach
preliminary study
• surveying applicable data sets on national and regional level
• verifying feasibility
• determining general approach
implementation project
• designing the methodological concept
• preparing the field work
• coordination of the first field survey
• drafting the indicator
• calculating the initial indicator value for Germany
First meeting of the Expert Committee on Evauation of Rural Development Programmes; Brussels, 15 Dec 2008
Implementation of the High Nature Value
Farmland Indicator
Outcome of the preliminary study
preliminary assignment of the HNV farmland units to the national
classification of biotopes/habitats and to the habitats according
to Habitats Directive
preliminary selection of animal and plant species suitable for
determining type 3 HNV farmland (23 bird species, 31 other
species)
evaluation of suitable datasets (habitat mapping, grassland
monitoring etc.)
evaluation of available remote sensing data

Implementation of the High Nature Value
Farmland Indicator
Results
recently no suitable datasets in Germany available to
measure HNV farmland on national level
satellite imagery based monitoring not feasible
recently established area-wide approaches of the federal
states to expensive, to unsteady, to heterogeneous
using the random sample approach of the national
Monitoring of Common Breeding Birds is possible and
inexpensive; methodology in accordance with the
biodiversity monitoring in Northrhine-Westphalia

Implementation of the High Nature Value
Farmland Indicator
Methods
stratified random sample, each sample unit with a size of
1km²
sampling design already established (1.000 sampling units
for results on national level; supplementary plots for detailed
studies on federal states level; stratification using land cover
and landscape types)
about 900 of 1.000 sample units comprising at least 5% of
agricultural area

Farmland Indicator
Advantages
assessment of HNV Farmland with low operation expense
statistically sound and reliable method: measurable
representativity
mapping the real situation, low fuzziness, calculable error
low costs
many possible synergies with other biodiversity monitoring
programs due to coherent survey methods and combination
of results or parameters

Next steps
refining the assignment of HNV farmland types to the
national biotope classification
preparation of a field handbook, aerial photographs and
other tools for the field mapping
organisation of the first field survey in 2009
development of the calculation procedure
calculation of the initial value for the HNV farmland indicator
up to 2010 to fulfil the reporting obligations

Time table and costs
May 2009
Field mapping in a small time frame
(probably another time frame for selected
HNV farmland features later in the year)
March 2010
Initial HNV farmland indicator value
Internal report
May 2010
Recommendations for optimization of the
monitoring programme
Reporting to the EC
Estimated costs: 200.000 € per survey (results on
national level)
