ALL-EMA is enshrined as an ‘agricultural environmental indicator’ in the concept of the agricultural environmental monitoring programme of the Swiss Federal Office for Agriculture, and was deliberately designed to complement the already existing and developing national monitoring programmes of the FOEN. In existence since the year 2000, Biodiversity Monitoring Switzerland (BDM) illustrates the most common species and habitats. With the impact monitoring of biotopes of national importance and InfoFlora’s Red List (RL) of Species, rare and endangered species and habitats are the primary concern.
The focus of ALL-EMA lies on the surveying of semi-frequent-to-semi-rare species and habitats which are of great importance for the Agricultural Environmental Targets, and which are only inadequately captured by the remaining programmes (see Figure)
For the calculation of the relevant indicators, in a first step, already existing data from Biodiversity Monitoring Switzerland was tested for suitability. The analyses made it clear, however, that these underlying data only permitted statements at a national level on few and very frequent habitats, and not, as required, on a regional level for moderately frequent habitats.
Synergies with existing monitoring programmes are also used in the ALL-EMA sampling design, however. For the vegetation surveys, the ‘Biodiversity Monitoring Switzerland’ method, which was also adopted by the ‘Impact Monitoring of Biotopes of National Importance’ programme, is being used. In this way, vegetation development can be compared from the point of view of the different monitoring programmes, and used for questions of interpretation.
