Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 15 7 18

Probable 25 12 29

Possible 26 20 33

Species Total 66 39 80

Total in Atlas 1132 1041 3854

Species Percentage 5.83 3.75 2.08

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.
