Hi Annie
I know these things aren’t easy. If there are a lot of people who have anecdotal evidence, and they wrote it down, maybe that would help. Or, if you’re really keen you could produce some sort of a survey. Of course, it would be relying on people’s memories, but maybe better than nothing. Probably of most importance in this case is whether local people have been seeing roadkilled hedgehogs.
But it does show the importance of people reporting hogs to the Big Hedgehog Map. Alive and dead.
Meanwhile, if you are talking about hogs to people, the most important thing everyone can do for them is to link their gardens with hog holes. That way there is less need for the hogs to cross the roads in the first place because they would be likely to have more suitable habitat without having to so much.
Good luck.
