This new study from Haigh et al. reveals aspects of hedgehog ecology through the study of carcasses on Ireland's roads. In corroboration with previous studies, the research found higher sightings of males than females, particularly in the height of the breeding season. Unlike other studies of hedgehogs in the UK, the research found that hedgehogs used a greater proportion of arable land than what was available to them. This should make us take stock of the greater number of hedgerows in Ireland than in England and the habitat structure, in order to improve arable land in England for hedgehogs, where they are severely in decline. Equally as important, the study also finds that hedgehogs appear to cross in key spots each year which could be vital in creating safe crossings for hedgehogs.
