Tajikistan’s Tigrovaya Balka Nature Reserve Under Threat
The International Union for Conservation of Nature (IUCN) has raised serious concerns about the condition of Tajikistan’s Tigrovaya Balka Nature Reserve, a UNESCO World Heritage site. The IUCN has classified the state of this rare ecosystem as “alarming,” citing deteriorating hydrological conditions and mounting risks to regional biodiversity. Located at the confluence of the Vakhsh and Panj rivers in southern Tajikistan, Tigrovaya Balka is home to Central Asia’s only remaining natural Tugai forest, a unique riparian ecosystem that depends on periodic flooding for its survival. The IUCN’s World Heritage Outlook uses four categories to assess sites: “good,” “good with some concerns,” “alarming,” and “critical.” In its latest report, the organization identifies water regulation on the Vakhsh River as the primary threat to the reserve. The construction of reservoirs and increased water extraction for agriculture have disrupted the seasonal floods that historically sustained the forest. Prior to the 1960s, before large-scale hydropower development began, spring floods replenished groundwater, restored ecosystems, and prevented soil erosion. Today, experts say, the Tugai forest relies almost entirely on surface runoff and drainage water, insufficient to maintain its ecological balance. The IUCN report notes that approximately one-third of the Vakhsh River’s flow is diverted for irrigation, while about 20% of the remaining water consists of chemically polluted wastewater. This contamination is degrading water quality across the reserve and contributing to the decline of rare aquatic species. “Pollution damages the aquatic ecosystem, and many species cannot withstand environmental changes,” the report states. The IUCN emphasizes that much of the available data is observational and requires further scientific validation. It recommends a comprehensive hydrological study that considers the effects of climate change to more accurately assess the threats facing the reserve and to develop effective conservation measures. Established on November 4, 1938, the Tigrovaya Balka Nature Reserve spans 49,700 hectares across the Dusti, Jaihun, and Kubodyon districts in the Khatlon region. Renowned for its natural beauty, it remains one of the Vakhsh Valley’s key ecological and tourist sites. The name “Tigrovaya Balka” (Russian for “Tiger Valley” or Beshaï Palangon in Tajik) commemorates the now-extinct Turanian tiger, which once roamed these lands. The last confirmed sighting of the species in the area dates back to the 1950s.
