Local Nature Reserves are places for people and wildlife – and you will be able to see a variety of habitats and species, and hopefully have a really good time outdoors! For an overview of LNRs in Cambridgeshire/Peterborough, see www.sssi.naturalengland.org.uk/Special/lnr/lnr_results.asp?C=5

In the Peterborough area, there is the Natural Networks map, which is a brilliant web facility to find good places to visit, and it includes some details of what you might expect to see there. See http://map.naturalnet.org.uk/index.php/
