That's the problem it takes time and effort to reverse the damage done and we humans are inherently lazy, always looking for the easy option even when we know it isn't the best. I feel for the Hedgehogs who are one of the best animals to have in your garden better and cheaper than any bug/slug killer but are being assaulted from every angle imaginable including robot lawnmowers. One way to look at it is they won't be assaulted much longer as they are close to becoming wiped out anyway.
