Permafrost Herds
A German researcher says that sending large herds of horses and other grazing animals to roam across regions where global heating is thawing the permafrost could help preserve about 80% of those soils in a frozen state until 2100.
Christian Beer points to Siberian studies where scientists resettled herds of bison, reindeer and horses more than 20 years ago.
They found that when the snow cover is scattered and compressed by the grazing animals’ stomping hooves, its insulating effect is dramatically reduced, intensifying the freezing of of the permafrost in winter.
