Hedgehogs declined due to the application of insecticides in vast quantities. The remaining starving population is vulnerable to predation by badgers who are similarly finding food hard to find at certain times of the year for the same reason.
Providing lots of insect rich habitat will help but it’s probably a losing battle.
Hares of course need a very different environment. Are there any nearby?
