For decades, conservationists in Tajikistan assumed that the striped hyena – a shy, less vocal cousin of the spotted hyena – was extinct there. But in 2017 a motion-sensitive camera trap in the country’s south-western corner, near the borders with Afghanistan and Uzbekistan, detected the presence of a female with cubs. The discovery stunned local observers, and ever since, one man and his colleagues have struggled to find out more about the few remaining Tajik striped hyenas with a view to saving them from oblivion. The challenges are immense, including the international animal parts trade, competition between animals and humans for habitat, and often-negative public perceptions of the hyena itself. Eight years on, Antonia Bolingbroke-Kent travels to the grassy lowlands of Tajikistan to join the small team in their fight to save these elusive, persecuted mammals, and in doing so learns how vital hyenas are to both the ecosystem and human health.
