Faunapassage under E20 ved Estrup Skov.
For at vildt frit kan vandre mellem Estrup Skov og Vejen Mose, er der lavet en faunapassage under motorvej E 20. Beregn ved simpel opmåling, hvor store dyr der vil bruge tunnelen.
For at dyr vil benytte en tunnel skal den erfaringsmæssigt have en vis størrelse.
Brug den empiriske formel for beregning af tunnelfaktor:
Tunnelfaktor = H × B / L større eller lig 0,75 for rådyr, 1,5 for då- og krondyr (Ingen enheder)
Question to answer:
Tunnelfaktor =0,75 A = 8
Tunnelfaktor =1,5 A = 7

For free migration of wildlife in the landscape there is a fauna passage connecting Estrup Skov and Vejen Mose, under highway E20. Make a simple measurement and calculate what kind of wildlife will pass through the tunnel. From experience a tunnel should have a certain dimension.
Use the emperical formula when calculating the tunnel factor:
Tunnelfactor = H x B / L is bigger or equal to 0.75 for roe deer, 1.5 for fallow deer and red deer (no unit is used)
Question to answer:
Tunnelfactor = 0.75 A = 8
Tunnelfactor =1.5 A = 7
