Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 203 141 230

Probable 40 36 47

Possible 48 44 63

Species Total 291 221 340

Total in Atlas 1132 1041 3854

Species Percentage 25.71 21.23 8.82

Species Total is the sum of all quads/priority blocks/total blocks the species was recorded in with at least a Possible breeding status. Total in Atlas is the number of quads/priority blocks/total blocks in the atlas with data (regardless of species). Species Percentage is the Species Total quads/priority blocks/total blocks divided by the Total in Atlas quads/priority blocks/total blocks.

Max Abundance # Total Blocks

Not Indicated 110

1 breeding pair 78

2-10 breeding pairs 139

11-100 breeding pairs 13

Number of Total Blocks is the number of blocks for which the indicated abundance is the maximum recorded for the species in the block. Abundance represents the estimated number of breeding pairs in a block.
