a seasonal basis. Tamástslikt also frequently hosts guest lectures that range from related museum work to sustainability and economics. Conservation and sustainability The Tamástslikt Cultural Institute participates in conservation efforts and strives for sustainability. Early in 2011, the Kinship Café “renounced Styrofoam” and committed to the use of biodegradable containers. Past improvements to the facility include the sealing of soffit vents, the installation of energy usage monitors, energy efficient lighting, and motion-activated fixtures, and the decentralization of large boilers. During the ten-year span from 2003 to 2013, the Tamástslikt Cultural Institute “successfully reduced electrical usage by 55% and natural gas usage by 75%.” Tamástslikt Cultural Institute subscribes to the triple bottom line, or “people, planet, and profit” approach put forth by John Elkington. Wind turbine A 50 kilowatt wind turbine is to be constructed in 2013. The turbine will be funded by “grant money from Pacific Power’s Blue Sky Fund and Oregon’s wind energy incentives,” and “will be congruent with Confederated Tribes of the Umatilla Indian Reservation wind policy – which is against wind farms but for wind power.” Museum governance The Tamástslikt Cultural Institute is "tribally owned and operated" by the Confederated Tribes of the Umatilla Indian Reservation, which totaled 2,860 enrolled members at the close of 2011.

The institute published 300,000 maps in 2011. Confederated Tribes of the Umatilla Indian Reservation In conjunction with the Confederated Tribes of the Umatilla Indian Reservation, the Tamástslikt Cultural Institute is contributing to efforts to rename Oregon places containing the word “squaw” with indigenous names. Reciprocal partnerships In 2005, the Tamástslikt Cultural Institute “entered into reciprocal membership agreements” with the Oregon Historical Society and Washington State Historical Society, which extends “free admission to their museums for members of any one of the respective institutions.” This agreement was made in honor of the Lewis and Clark bicentennial and Walla Walla Treaty Council sesquicentennial. The museums collaborated previously in 2001 to develop a Dale Chihuly exhibit, and
