Figure 27. Number of Breckland conservation priority species from the grazed, but no or infrequentdisturbance (GRAZ-NDIST) guild in each of the 1 km grid squares in the Breckland region. There are 81species in this guild. Species requiring scrub in addition to these conditions were excluded. White indicatesareas for which no records were obtained.140
