NDSU Karasch butterfly patch burn study – early results
A study on butterflies in managed grazing systems in the Great Plains, conducted by researchers at the Range Science program at North Dakota State University, looks at two versions of patch-burn grazing: “PBG1” has one prescribed burn in the spring, and “PBG2” has one in the spring and one in late summer. “SLG” is season-long grazing. Each column shows the average numbers of butterfly species, butterfly detections, flower species, and flower density per transect within each treatment. (Image credit: Brooke Karasch)
