In agroecosystems ground refuges at the base of hedgerows represent key habitats for many animals.
We used non-lethal rapid biodiversity assessments to sample various morphospecies in hedgerows.
We used co-inertia analyses, a functional index, and predator abundance to compare hedgerows.
Ground refuge availability markedly influenced biodiversity and predator abundance.
Surveys and replanting programs should integrate ground refuges as key elements.
