The world's longest terrestrial migration

Researchers published this year that there is a transnational migration of Zebra between the Caprivi region of Namibia and Botswana.  This migration which thousands of zebras take every year is more than 5 thousand kilometers long and starts by the Chobe River Flood plain and goes to the Nxai Pan National Park during the wet season.

Researchers tracked the migration over several years. In order to track specific zebra they tranquilized some by helicopter and attached GPS tags to them.  Then using the GPS trackers on dozens of individuals they tracked the path of the migration.

This research can help give data to both the Namibian and Botswanan governments to protect migration route and avoid building in this area.

It is interesting to see how this large migration relates to the large veterinary fences that both Namibia and Botswana have set up. This one population of zebra does not go within and of the areas of fence, but were there once larger migrations that the fences have diminished? Has the red line veterinary fence hurt the natural tendencies of large wild populations of megafauna?

What migrations no longer exist because of humans? In Namibia or California?
