Hi Ekay, whereabouts are you (rough location)? We moved to this garden 18 months ago and were thrilled to find hedgehog droppings, and then when my daughter was visiting and sitting out on the bench late one evening (smoking
) she was startled by a rustling in the undergrowth and watched a very large hedgehog snuffling about the garden. 'When we had the new fencing installed our builder cut 'hedgehog gates' in the panels to ensure that hedgehogs could roam from garden to garden, and we started putting a dish of dry hedgehog food out in the evenings and were woken in the early ours of summer mornings by the sounds of the dish being pushed around on the terrace. We also make sure there's a dish of rainwater available every evening, as the dried food is quite 'dry'. The dish is usually half empty in the morning. Although we've had to cut back some of the undergrowth and have some trees removed ('orrible conifers that had been topped and lopped badly) we are replanting shrubs etc to provide cover and in the meantime we're leaving messy corners (piles of old runner bean haulms etc) and put three hedgehog houses in quiet corners (one purchased and two home made). We're 99.9% certain that two are currently occupied by hibernating hedgehogs. We are situated near the edge of a 'suburban village' with marshes, woodland and a golf course nearby and I have been surprised at the amount of wildlife we see in the garden.
Perhaps it might be that there's so much 'hedgehog friendly' habitat where you live that they're spoilt for choice - or maybe they're out there and you've just not seen them - yet
There have been several threads about hedgehogs on this board over the past year or so, including threads about rescuing them when they've been too small to hibernate. I suppose that if you're sure you've not got any hedgehogs nearby and the habitat is suitable you could contact one of the rescue centres and offer a home to one or two?
