Edible dormice (Glis glis) avoid areas with a high density of their preferred food plant - the European beech

Table 1 Environmental variables determined either from a GIS based forest inventory or small scale measurements in the forest

Source	Variable	Abbreviation	Unit
GIS based	Altitude	“alt”	m above sea level
100 m Radius	Forest age	“age”	years
	Fagus sylvatica density	“fag”	%
	Conifer density	“conifers”	%
	Slope	”slope”	degrees
Small scale	Canopy closure	“can”	25%, 50%, 75%, 100%
30 m Radius	Girth of nest-box tree at breast height	“girth”	cm

Canopy closure was measured by partitioning the space around the crown into four quadrants and considering the connection between this crown and neighboring trees. The variable is equal to 100%, if all four quadrants are connected
