Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 999 962 1330

Probable 65 66 188

Possible 10 8 62

Species Total 1074 1036 1580

Total in Atlas 1132 1041 3854

Species Percentage 94.88 99.52 41.00

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.
