• Resumen

  • Penny van Oosterzee expresses her surprise upon knowing that southern Africa's great plains are emptied from migrating wildlife and how her and her team of ecologists from Australia were confronted by a profusion of fences that sliced across the landscape. Michelle Gadd of the US Fish and Wildlife Services also states how the different varieties of fences, from simple wire-strand cattle fences to 2-metre-high, double-layered ones set with a gap of 10 metres or more in between, free of large mammals makes it a substantial modifier of the landscape, extinguishing entire migrations and even pushing species to extinction. She also adds how the impact assessment of her study and the recommendations to relocate the fences where mostly ignored and the use fences for political purposes instead for the ecological ones.
