In 1998, 31 Przewalski’s horses entered Chernobyl and reached 137 by 2018
A study reveals that a small group of Przewalski’s horses introduced to the Chernobyl Exclusion Zone in 1998 successfully established a breeding population. Despite initial challenges like poaching and transport stress, the population grew significantly over two decades.
Why it matters
This case study provides unique insights into the resilience of endangered species in abandoned, radioactive environments and the long-term success of rewilding efforts.
When the Chernobyl Exclusion Zone was abandoned after the 1986 nuclear disaster, it was not expected to become part of the future of a horse that had already vanished from the wild. Yet, more than a decade later, Przewalski’s horses were brought into the largely empty landscape in an effort to establish a free-ranging population. According to the study published in Theriologia Ukrainica, titled ‘Przewalski`s horse (Equus ferus przewalskii) in the Chornobyl Exclusion Zone after 20 years of introduction’ claim that 31 horses were released in 1998 and multiplied. The records tell a more complicated story. The animals arrived over two years, some died before joining the wild population, and poaching caused serious losses during the first decade. Even so, the horses continued breeding.
