Hedgehog Helpline

This is such a sweet charity, concentrating all their efforts on rescuing sick, injured and orphaned hedgehogs with the intention of reintroducing them to the wild once they are ready. And no hedgehog casualty is turned away.
They don’t receive any funding, so rely entirely on the generosity of the general public and their volunteers.
Usually, members of the public bring in hedgehog casualties, and the charity then tries to get the hedgehog back to health so that they will be able to survive in the wild. When they’re ready, they’re released somewhere suitable.
The charity also offers free advice on hedgehog matters, if you have any questions — including how to encourage them into your garden, and how to offer basic first aid and care.
Although they’re a small organisation with few volunteers, I think they do a wonderful job — in 2009 they received around 518 hedgehog casualties, and gave telephone advice in relation to a further 1007 hedgehogs.
