Burrow Geometry and Hazards: Case Histories of GPR for Mapping Animal Burrows

Ground Penetrating Radar has a vast range of applications: from geologic mapping to concrete inspection. A recently emerging application is that of biological investigations through this non-invasive technique. Geophysical mapping of features such as tree roots and turtle burrows have proved to be valuable techniques for the understanding of these subsurface systems. We present three case histories of GPR investigations pertaining to animal burrows: cutter ants in Brazil, groundhogs in Michigan, and groundhogs in Pennsylvania.
