A River, A Mission, A Legacy
Ilenkh was born from a simple but urgent conviction: the Ilenkh River and its native fish species were disappearing, and someone had to act. What began as a small group of Mongolian scientists and conservationists in the early 1980s has grown into one of the country's most respected freshwater conservation organizations.
Today, our work spans population monitoring, community education, habitat restoration, and policy advocacy — all anchored by the belief that healthy rivers are the foundation of healthy communities.

Key Milestones
First Survey of the Ilenkh River Basin
A team of Mongolian ichthyologists conducts the first systematic survey of fish populations in the Ilenkh river basin, documenting taimen, lenok, and grayling populations across 14 monitoring stations. The findings reveal alarming declines linked to overfishing and habitat degradation.
Founding of Ilenkh
Following years of independent research, a coalition of scientists, local community leaders, and international supporters formally establishes Ilenkh as a conservation organization. The founding mission: protect the ecological integrity of the Ilenkh River and its native fish species for future generations.
First Taimen Protection Program
Ilenkh launches its inaugural Hucho taimen monitoring and protection program — the first of its kind in Mongolia. In partnership with herder communities along the river, the program establishes seasonal fishing restrictions and no-take zones in critical spawning areas.
International Recognition & First Partnerships
Ilenkh receives recognition from the International Union for Conservation of Nature (IUCN) and establishes its first formal partnerships with international conservation bodies. Funding expands to support water quality monitoring, expanded population surveys, and the first community ranger training program.
Community Guardian Program
The Community Guardian Program trains and certifies local herders as conservation stewards, giving communities a formal role in river monitoring and protection. Over 60 guardians are certified in the first year, covering 280 kilometers of the Ilenkh watershed.
Habitat Restoration Initiative
A three-year habitat restoration initiative begins, targeting riparian vegetation loss and erosion along key tributaries. Working with local governments and herder associations, Ilenkh oversees the restoration of over 40 hectares of riverbank habitat.
30th Anniversary & Research Center Opening
Ilenkh marks its 30th anniversary with the opening of the Ilenkh River Research and Education Center. The facility houses field equipment, a specimen library, and classrooms used for training researchers and educating local school children about freshwater ecology.
Annual Survey Shows Signs of Recovery
The 2024 annual taimen population survey — conducted across 22 monitoring stations — documents the first statistically significant signs of population recovery in monitored stretches. Lenok and Arctic grayling populations also show stable or improving trends, a testament to over three decades of sustained conservation work.
