As Global Tiger Day rolls around, there’s good news for the big cats in Thailand. The tiger population in the country’s Western Forest Complex (WEFCOM) — an 18,000-square-kilometer (6,950-square-mile) area of forest encompassing 11 national parks and six wildlife sanctuaries — is estimated to have more than tripled between 2007 and 2023, from 41 to 143. The remarkable comeback was observed in a new collaborative study led by Thailand’s Department of National Parks (DNP) and the Wildlife Conservation Society (WCS), newly published online in the scientific journal Global Ecology and Conservation.
