Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 283 182 398

Probable 101 86 128

Possible 123 130 173

Species Total 507 398 699

Total in Atlas 1132 1041 3854

Species Percentage 44.79 38.23 18.14

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.
