These maps give a general idea of the suitability of locations for Barn Owls. This can be used to plan future Barn Owl conservation action. For example, you can find out if installing a nestbox in your area is worthwhile.

How can I find my location on these maps?
The 10km Ordnance Survey grid-squares and names are shown on the maps. Each coloured cell within them represents a 1 km square.
- The 100km square SE.
- The 10km square SE49.
- The 1km square SE4292.
Finding your location if you don't know your OS grid-reference
Go to the Postcode to 10 km square converter and enter your postcode to find out which 10 km square you are in.
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 1 km 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
The development of the habitat suitability map was greatly assisted by Dr. Barb Anderson as part of a UK Population Biology Network (UKPopNet) project 'Modelling distribution changes in British animals and plants' which was funded by the Natural Environment Research Council (Agreement R8-H12-01), English Nature and latterly by Natural England.
