Board of Supervisors


Jeanette Dorner, Chair (Elected Position, 2021-2024)
Jeanette first began working with the Pierce Conservation District in 1996 when she created a community group to restore the health of Muck Creek and the District became a major supporter of that effort. She worked for 11 years as the Salmon Recovery Program Manager with the Nisqually Tribe, coordinating the protection and restoration of the Nisqually watershed, then five years as the Director of Ecosystem Recovery at the Puget Sound Partnership. She now is the Executive Director of the Mid Sound Fisheries Enhancement Group, a non-profit group working with people in the Mid Puget Sound region to restore salmon habitat and recover salmon populations. Jeanette believes strongly in the mission of the conservation district to empower local landowners to be good stewards of their lands through voluntary and incentive programs and to ensure that our Pierce County community has access to healthy local foods that are sustainably produced.

Associate Supervisors

Associate Supervisors are a key component of the District’s interactions and communication with our community and the residents we serve. Associates can serve as advisers to the Board in an area of expertise, represent a sector of our community or an industry, assist with special committees, and support other District initiatives as directed by the Board of Supervisors. Associate Supervisors do not have the authority to vote on the board’s official actions but are a critical component to the success of our organization.  

We are currently accepting applications for Associate Supervisors.
