Who leads our work

The Woods & Wetlands Group is guided by an all-volunteer Executive Committee of up to seven elected members. Members serve 2-year terms. Elections are held annually.

Our Executive Committee meets once a month to manage operations related to our conservation, advocacy, and political action priorities, and to plan outings and social activities for members.

All meetings of the Executive Committee and its committees are open to all Sierra Club members.
