Assessments reported on

 
 
 
In total, 12,937 feature assessments carried out between April 1998 and March 2005 were reported.  It is estimated that this number represents 57% of the total of features in the United Kingdom under the various designations (Table 1).  While this falls short of the 100% intended, it nonetheless represents the most comprehensive assessment of the United Kingdom's designated features ever undertaken, and one of the most comprehensive assessments by any country in the European Union.
