The reintroduction of about twenty species of mammals in certain areas of the world will restore ecosystems and mitigate global warming. An international team of researchers has pinpointed the relevant species and ecoregions. The 30 Million Friends Foundation calls on the government to implement these recommendations.
The European bison, the wolf, the reindeer, the lynx… There are so many animals whose reintroduction will 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) of the United Nations Environment Program (“Ecoregional Approach to Restoring the World’s Intact Large Mammal Communities”, Ecography2022).
Positive impact on biodiversity and global warming mitigation
Reintroduction is possible in a wide variety of natural areas of the planet.
J. Gosling – researcher
To justify their work, the scientists cite the environmental benefits associated with the reintroduction of the gray wolf into Yellowstone National Park in 1995: ” The reintroduction of one missing species from this ecoregion had and still has a huge positive impact. “. Indeed, by making their prey – herbivores – move, predators participate in the regeneration of rivers and grasslands. However, the diversity of vegetation itself contributes to the development of many endangered species, such as beavers, which, in turn, contribute to biodiversity. Their work is an environment habitat, breeding and feeding of many animals such as voles, wild birds, amphibians and aquatic insects!
At the same time, the development of plant biodiversity makes it possible to capture and store CO2.2 in the ground, up to reducing greenhouse gas emissions. Thus, the recreation of a group of mammals is actively involved in the fight against global warming!
Twenty species of mammals
In total, the researchers identified 20 mammal species (7 carnivores and 13 herbivores) whose reintroduction (or augmentation) into this ecoregion would result in significant ecosystem benefits. These reintroductions are possible” in the most diverse natural areas of the planet says Joe Gosling, co-author of the study.
This re-introduction should be a national and international goal.
There are at least 35 ecoregions in Europe whose ecological balance would benefit from the return of certain animals such as the wolf, lynx, reindeer, aurochs and the Eurasian beaver. It’s the same in North America with the black bear, the American bison, or the wolverine. In Asia, the reintroduction of wild horses and wolves into the Himalayas would greatly increase biodiversity. For its part, the fauna and flora of Africa would benefit from the reintroduction of cheetahs, lions or hippos.
Already successful reintroduction programs
” A priority action would be to consider this reintroduction as a national and international goal. recommends J. Gosling. Now it is up to decision makers to put the results of this research into practice.
The 30 Million Friends Foundation has already reported on the effectiveness of endangered species reintroduction programs. This was the case with the European beaver in France and England, and the wildcat in Scotland, or even the white-tailed eagle in the United Kingdom.
