The reintroduction and rehabilitation of species is often the basis of rewilding or restoration of lands. What happens if the species you wish to reintroduce is no longer available? What happens if the animal you want to reintroduce is no longer only extinct locally, but has disappeared forever?
This may sound like Jurassic Park. This is happening in real life with the Aurochs (Bos primigenius). Since the death of the last cattle in 1627 in Poland, this wild ancestor has lost.
Aurochs have been a part of the human mind for as long time as humans have existed, as evidenced by their prominent status in cave art. The advent of agriculture and domestication led to the extinction of this magnificent animal.
Bring The Aurochs Back Lands
Why, and how can we bring the Aurochs back? What is the likelihood of this outcome?
Aurochs are represent in cave paintings. Some fossil remains have found. There are also some historical descriptions. Commentarii de bello Gallico, the Roman emperor Julius Caesar wrote, Their strength is extraordinary.
The historical record of this animal is very sparse, despite its former wide range of habitat (from the Fertile Crescent and the Iberian Peninsula to Scandinavia and the Indian subcontinent), but it has a lot of history. It is likely that its behaviour, size, and temperament have changed across environments. Despite these variations, the Auroch survived to modern times as the primordial, powerful, and immense ox.
Today’s theory is that Aurochs’ traits have survive and genetically distribute among its descendants. These traits can be re-create by breeding them together and choosing offspring with more Aurochs-like traits. This is call back-breeding, literally: breeding backwards.
Two brothers, Lutz Heck and Heinz Heck, were the first to try to revive the Aurochs. They had an undeniable Nazi party affiliation https://126.96.36.199/judi-bola/agen/bolapelangi2/.
The Heck cattle, also known as the Heck, was create in 12 years. It combines domestic cattle with Spanish fighting bulls. The brothers were more concerned with size and aggression than the Anatomical Description of the Aurochs. Heck cattle are not consider extinct today because of this.
Heck cattle survive World War II and now found in pastures and zoos across Europe. Although they are not Aurochs, many people find that they can do the Aurochs’ work just fine. They are use as grazers in Oostvaardersplassen, a Dutch nature reserve.
Recreate Wilderness Lands
It was believe that Europe’s landscape before the arrival of humans was mostly forest for most of the 20th Century. Frans Vera, a Dutch biologist proposed that Europe’s primeval landscape was compose of meadows, forests, and other habitats. He argued that this is because large animals, such as the Aurochs, would have created this landscape using their grazing behavior, now called natural grazing.
Vera founded the Oostvaardersplassen to prove that he is correct. To see what happens to the land when there are many grazers, the Heck cattle herds were created.
Many are interested in natural grazing and want to bring grazing animals onto new land to create a European wilderness. The drive to recreate the Aurochs is largely driven by this push for wild grazing animals.
