Just read the HPS/PTES report that is used in the OP and it has this to say on badgers:
Are badgers responsible for the hedgehog decline?
Badgers are most abundant in lowland pastoral landscapes (over half the population is in the south-west of England and south Wales), areas where hedgehogs are comparatively scarce. The two species compete for food, such as earthworms and beetle larvae, and badgers will also eat hedgehogs. When they are foraging, hedgehogs tend to avoid areas where badgers have recently been active.
But while competition, predation, and avoidance are likely to reduce hedgehog numbers in areas with lots of badgers, the two species can co-exist and, moreover, in a national survey, hedgehogs weren’t found in 71% of rural sites where there are no badger setts.
Researchers at Nottingham Trent University are trying to understand the interaction between badgers and hedgehogs more fully and the extent of competition between the two species
