Hedgehogs in decline

I've noticed a significant decline in hedgehogs when I visit Britain. I used to see them in my father's garden but not for several years. Apparently there has been a 37% decline in the last decade. 'The biggest issue is the loss of habitat, such as hedgerows, and bigger intensively-farmed fields. In urban areas, the use of fences makes many gardens inaccessible, while paving and decking are not good hunting ground.'  http://www.dailymail.co.uk/news/article-2268579/Fears-future-hedgehog-number-declines-past-decade.html
