Horned Lark Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 153 123 167

Probable 230 212 292

Possible 113 112 145

Species Total 496 447 604

Total in Atlas 1132 1041 3854

Species Percentage 43.82 42.94 15.67

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.
