Basis for sampling strategyBasis for sampling strategy

Grid of 10X10 km = 326 cells

Three samples per grid cell = 978 samples

Take into consideration:→ Major biotopes→ Seasonal variation→ Import risk

Proposed procedureProposed procedure

Identify key habitats based on Corine LC classes by aggregating urban, agriculture, natural and import risk classes.

Calculate total surface per aggregated class

Assign proportional number of sample points to aggregated class.

Generate appropriate number of random sampling points within each class.

Randomly assign sampling points within each class to two sampling seasons.

Geocode and assign sample sites per team.

CORINE includes 50 classes divided in five groups:→ Artificial surfaces including

urban and industrial→ Agriculture areas→ Forest and semi natural

areas→ Wetlands→ Water bodies
