Grasshoppers signal slow recovery of post-agricultural woodlands, study finds
New research by Philip Hahn and John Orrock at the University of Wisconsin–Madison on the recovery of South Carolina longleaf pine woodlands once used for cropland shows just how long lasting the legacy of agriculture can be in the recovery of natural places. By comparing grasshoppers found at woodland sites once used for agriculture to similar sites never disturbed by farming, Hahn and Orrock show that despite decades of recovery, the numbers and types of species found in each differ.
