List_of_Sites_of_Special_Scientific_Interest_in_West_Yorkshire
This is a list of the Sites of Special Scientific Interest (SSSIs) in West Yorkshire. English Nature, the designating body for SSSIs in England, uses the 1974–1996 county system, and the same approach is followed here, rather than, for example, merging all Yorkshire sites into a single list.
For other counties, see List of SSSIs by Area of Search.
