My girlfriend and I are lucky to live right at the foot of the South Downs. The little lane we live on is well travelled by walkers and indeed there are local leaflets showing good walks that pass direcly by our front door.
Figuring that deer are going to be giving birth over the next few months, I grabbed a couple of the BDS posters about not touching "baby deer" if found and have put them up outside the house where walkers will see them as they go past.
Hopefully it will get the message out to a few more people to leave "abandoned" youngsters alone.
The poster is available here The British Deer Society - abandoned fawn
