Visitors have been spotted feeding the deer from their cars, something Mr Barrett said put the animals in great danger.
“They lose all the inhibitions, they lose all the fear and they associate cars with food,” he explained.
“They’ll happily approach a car in search of a few tidbits, and that’s where we start getting deer-vehicle collisions.”
Staffordshire County Council echoed Mr Barrett’s requests and advised that motorists be prepared to stop, avoid sudden swerving and be ready to dip their lights when meeting a deer in the road.
The authority said full beam lights could cause the deer to freeze and make them difficult to avoid.
