Table 1. Defined habitat classes aggregated from single habitats and separated by edges or areal characteristics.

Geometric habitat properties	habitat class	habitat class abbreviation	description of individual habitats
in edge habitats (non-agricultural)	ditches-grassy	DG	ditches (pipe culverts included) and grass strips (apart from adjacent farm tracks)
	fallow-storage	FS	barns, fallow land, ruderal sites surrounding winddriven power generators or fences or human-related storage yards, silage
	copses-hedges	CH	wooded habitat such as trees and shrubs that stand together in groups and whose geometry is linear (hedges) or planar (copses)
	residential associated	RA	allotments, gardens, areas surrounding buildings, recreational areas (sports, riding etc.)
	road side ditch	RD	strips up to 5 meters wide along each side of the road; area of road asphalt is excluded
	field tracks	TR	asphalted, gravelled or unmade farm tracks with grassy double wayside or with one-sided grassy strips and a ditch on the other side
outside edge habitats (agricultural)	pasture	PA	pastures, meadows
	crops (four buffer classes)	C20 C60 C100 C>100	arable land with crops and non-tilled fields (divided into buffer classes starting from the adjacent edges: 0–20 m (C20), 20–60 m (C60), 60–100 m (C100) and >100 m (C>100))
