Prof. Jens-Christian Svenning's inspiring talk held 2 weeks ago for Naturnahe Weidelandschaften e.V. is online now. No one else can argue as clearly & precisely for integrating grazers into modern conservaton. Great thanks to you, Jens!

The greatest beasts are gone, but maybe the land still remembers.
Another version of the idea of ghosts of lost beasts, this time the spirit of a mammoth walking with a bison somewhere in the fragments of the American prairie that still exist.

Es wundert mich, wie sich so viele Menschen, die sich mit der Natur beschäftigen, eine wilde Natur ohne Großherbivoren vorstellen können. Sie waren immer hier.

Sogenannter Prozessschutz oder Wildnis macht keinen Sinn, solange wir die natürlichen Prozesse nicht erst wiederherstellen: natürliche Hydrologie und Beweidungsregime.

Der größte Fehler ist, wenn dort die Dynamik verloren geht. Die militärische Nutzung hat tolle Lebensräume geschaffen- auch durch Störungen.
… einfach Wildnisgebiet sagen und nichts mehr tun ist dann absolut fatal.

Visited #RandersRegnskov today with my son. We noticed the Spotted hyenas sported a winter coat. A reminder that these predators are well adapted to colder climates. We may think of them as African today, but Spotted hyena #Crocutacrocuta roamed western Europe until 12000 years ago #reintroduction ?
