Hedges and the edge effect

Combes and fields surrounded by hedges and spinneys, trees scattered in the middle of pastures: these are all elements that make-up what is referred to as the “edge effect”. This term is used to describe the remarkable diversity in which open-environment species, forest-environment species and species that thrive in the areas in between open landscapes and forests meet. This diverse vegetation has many surprises in store along the sides of pathways and is highly useful for farming: it provides protection against prevailing winds, limits surface runoffs and provides shelter for the crop-pest predators (such as foxes who feed on voles).
