Ruffed Grouse Map and Data

Max Breeding Status # Quads # Priority Blocks # Total Blocks

Confirmed 459 404 545

Probable 150 148 206

Possible 90 97 167

Species Total 699 649 918

Total in Atlas 1132 1041 3854

Species Percentage 61.75 62.34 23.82

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.
