Watercourse monitoring network

Field workers survey aquatic invertebrates over a section of 5 to 100 metres in length, depending on the width of the watercourse. The animals are collected for identification in specialised laboratories.

Landscapes monitoring network

Field workers record the plants, butterflies and breeding birds over an area of one square kilometre. They generally follow a precisely defined route along paths and roads.

Terrestrial habitats monitoring network

Field workers monitor the selected species groups over a circular area of 10 square metres. They collect the vascular plants directly on-site. They take samples of moss types and snails for analysis in specialised laboratories.
