Info

It should be recognised that the Biodiversity Audit is not able to examine whether the designatedsites are concurrent with the distribution of priority species, as monitoring and survey has beenbiased strongly towards designated sites. However, it is likely that important localities exist onfarmland and waysides.Table 16. Number of species with conservation designations or Breckland specialist status by the numberof 1km squares (within the wider Breckland region of 23 10 km squares) in which they occur. Note a smallnumber of species were only recorded on a 10 km basis and therefore are not included in this tableNumber of 1km squaresDesignation/Category 1-9 10-24 25-49 50-99 ≥100RDB 450 49 29 22 29BAP 134 23 35 33 28Notable/Status 1033 142 45 12 13Breckland Entirely Restricted 11 1 3 3 1Breckland Largely Restricted 2 1 1 0 2Breckland Primarily Stronghold 25 10 1 2 2Breckland Secondary Stronghold 45 23 10 6 590
