Reintroduce mammals to restore ecosystems!

The reintroduction of about twenty species of mammals in certain areas of the world would make it possible to restore ecosystems and mitigate global warming. An international group of researchers has accurately identified the species and ecoregions in question. The 30 Million Friends Foundation calls on public authorities to implement these recommendations.

European bison, wolves, reindeer, lynx … So many animals whose reintroduction would benefit ecosystems and the climate! This theory has been scientifically proven and supported by researchers in consultation with the Resolve Association and the World Conservation Monitoring Center (WCMW) under the United Nations Environment Program (“An ecoregion-based approach to restoring the world’s intact large mammal collections”). Ecography2022).

Positive impact on biodiversity and mitigation of global warming

Gene introductions are possible in a large number of natural areas on the planet.

To justify their work, the researchers cite the ecological benefits of the reintroduction of the gray wolf in Yellowstone National Park in 1995: ” The reintroduction of a single species lacking from this ecoregion has had and still has a huge positive effect In fact, predators force their prey – herbivores – to move, predators participate in the regeneration of rivers and meadows. their works represent a habitat, reproduction and feeding area for many animals, such as mice, wild birds, amphibians and aquatic insects!

At the same time, the development of plant biodiversity makes it possible to capture and store CO2 in the ground so that greenhouse gas emissions are reduced. The rebuilding of a group of mammals is thus actively participating in the fight against global warming!

Affected twenty species of mammals

In total, the researchers identified 20 mammalian species (7 carnivores and 13 herbivores) whose reintroduction (or increase) to a given ecoregion would result in significant ecosystem benefits. These reintroductions are possible ” in a wide variety of natural areas on the planet “says Joe Gosling, co-author of the study.

This reintroduction must be a national and international ambition.

In Europe, there are no less than 35 ecoregions whose ecological balance would benefit from the return of certain animals, such as the wolf, the lynx, the reindeer, the European bison and the Eurasian beaver. The same in North America with the black bear, the American bison or the wolverine. In Asia, the reintroduction of wild horses and wolves in the Himalayas would significantly increase biodiversity. The fauna and flora of Africa, for their part, would benefit from the reintroduction of cheetahs, lions or hippos.

Already successful reintroduction programs

A priority effort would be to consider this reintroduction as a national and international ambition. recommends J. Gosling. It is now up to the public decision-makers to put the results of this study into practice.

The 30 Million Friends Foundation has already reported on the effectiveness of endangered species reintroduction programs. This was the case for the European beaver in France and England, but also for the wild cat in Scotland, or even the sea eagle in the United Kingdom.
