The list below shows the 69 Sites of Special Scientific Interest (SSSIs) in the Lancashire area of search. Note that English Nature, the designating body for SSSIs in England, uses the 1974-1996 county system, and this list follows the same approach. Some sites that might be expected to be here could therefore be in the Merseyside or Greater Manchester lists.
Of the 69 sites listed, 14 are listed purely for their geological interest, and 49 are listed for biological interest. A further 6 sites have both geological and biological significant features.
For other counties, see List of SSSIs by Area of Search.
