Introduction
Overview on methods of the LISA-study
Results of the LISA-study
Key findings / outlook on greening
Conclusions
The LISA-study
“Landscape Infrastructure and Sustainable Agriculture”
has been supported by the Joint Research Centre (JRC)
of the European Commission and
the European Environmental Bureau (EEB)
and further institutions and surveyors

Aims and methods of the LISA study
LISA = “Landscape Infrastructure and Sustainable Agriculture”
To produce…
Rapid, repeatable and easily obtainable records of the extent, quality and state of
landscape infrastructure, land use and ecological value of farmed landscapes in
different EU countries
 Data on the relationship between biodiversity and land use
 Good and bad practice examples of land use
 Evidence to support a future common European approach
 Data to evaluate the effects of CAP pillar I greening
3 elements of the approach:



Mapping of sample plots
in different regions (500 x 500 m)
Detailed vegetation transects

Results - key findings of the European LISA study
 In over 95 % of all investigated arable plots very low levels of
biodiversity were found:
only 0.9 key species were found in arable plots (n = 1528);
a sufficient level would be at least 3 -4 key species in average.
 There was an extremely low pollination potential of arable fields:
only 1.1 flower density on a scale 1 to 5 of all arable transects (n=1528).
 Buffer strips comprised in average in all regions 0.3 % of the arable land
(values of 0 % - 1.4 %).
 Landscape elements comprised mostly 2 – 7 % of the landscapes.
 In grassland regions the number of key species was higher: 2.2. - 17.7 species in
average; however, in intensive grassland regions it was nearly as low as in arable land.
 Good and bad land-use practice examples could be photo-documented.
 The LISA – methodology proved to be successful: within short time
comparable results in many European regions could be gathered.

▪
EFAs physically in total 1.37 Mio ha = 11.5 % of all arable land
Thereof 68 % catch crops and 12 % Nitrogen fixing plants
About 0,27 Mio ha EFAs with high ecological effectivity
thus = 2.3 % of all arable land

Greening from 2015 - conclusions
▪ EFAs with a high ecological effectivity comprise only about 20 % of
the German EFAs and thus only about 2.3 % of the arable land
▪ from scientific evidence at least 10-15 % of highly effective EFAs are needed
to stop the loss of biodiversity
▪ main lack of current EFA types are highly diverse arable fields (cropped with a
medium landuse intensity), buffer strips, flower strips and fallow parcels
▪ important for the CAP midterm review: investigation of
- the performance of buffer strips
- pollination packages in arable farming
- monitoring of biodiversity in arable land and grassland related to
CAP-targets 2014-2020 and the biodiversity 2020 strategy of the EU
▪ LISA study is beneficial for comparison in 2016
 what will change with greening, e.g. number and width of buffer strips
 changes in biodiversity (most important EFAs types)
 comparable approach for whole EU
