The Taimen Fund was originally established in 2009 as a program within the Tributary Fund, a Montana based 501c3 that was performing a variety of successful conservation projects throughout the Eg Watershed. The Tributary Fund, through the leadership of the Executive Director, Betsy Gaines Quamann, established a unique program combining conservation through culture that, most notably, rebuilt the Dayan Derkh monastery along the banks of the Uur River in 2004.

The Taimen Fund’s original program was specific to curbing poaching within the watershed. In 2013 The Taimen Fund inherited its now 501c3 status from its predecessor and continues to work with anti-poaching, and has broadened its efforts funding scientific research, community outreach and education.
