Understanding the maps
Blue – Landscape generally unsuitable for Barn Owls.
The altitude/habitat/winter climate determine the area to be largely unsuitable for Barn Owls. However, if Barn Owls are already present, encourage as much as possible with the creation of foraging habitat and nestboxes.
Yellow Hatched Areas – Motorways and dual carriageways. No nestboxes should be erected within 1km of major roads unless the road is screened by hedges or continuous tree lines immediately adjacent to the road surface.
Also displayed on the maps are landscape features to help you identify your location/study area. These are:
Blue lines – Rivers and canals
Black lines – Minor roads
