The diversity of the shrub species that make up hedges, their height and their varying density attract a diverse range of insect, bird and reptile species, and even some mammals who favour this dense and protective environments. In the summer, you may be lucky enough to see a red-backed shrike perched on a high branch searching for prey, a mimetic praying mantis camouflaged by the leaves, or a green whip snake coiled up under bush formations. Hedges provide a variety of micro-habitats, which allow many species to travel and are therefore real biological reservoirs and corridors that should be preserved.
