Wolves return to Netherlands after 140 years
Wolves were hunted out of many European countries over a century ago but have gradually been migrating back across the continental mainland.
Occasional wolf sightings have been made in the Netherlands since 2015.
But these animals were previously thought to be animals that had crossed over temporarily from Germany and would subsequently return there.
Ecologists from campaign groups FreeNature and Wolven in Nederland have been tracking two females in the Veluwe area, collecting wolf prints and scat (droppings) from which they can identify DNA.
