There are 69 sites of biological importance in Wirral. 
 
These locally designated sites are protected through the Unitary Development Plan (UDP) process under UDP Policy NC5.
 
The schedule of sites of biological importance is a material consideration in the determination of individual planning applications.
 
Since the adoption of the UDP in 2000 the sites have continued to be surveyed, initially by Wirral Wildlife, with the assistance of other specialist wildlife groups, and more recently by the Wirral Local Wildlife Sites Partnership.
 
This has resulted in two formal revisions to the schedule of sites of biological importance in 2011 and 2017 to reflect current ecological value.
 
The latest schedule, a summary of the changes since 2000 and the reports of each review can be viewed below:
